Date Posted: May 7, 2012


Title: CPT Spanish Atoms Not Released

Problem: Approximately 4,000 CPT Spanish Preferred Term (PT) atoms were erroneously not released in MRCONSO.RRF (MRCON and MRSO for ORF). 

Solution: This error will be corrected in the 2012AB Release.

Date Posted: May 7, 2012


Title: ICD10CM_2012 to ICD9CM_2012 Reimbursement Mapping Errors


  • MAPSETCUI C3264360 in MRMAP and MRSMAP (ICD10CM_2012 to ICD9CM_2012 Reimbursement Mapping) has 669 rows with false positive mappings. The value of the TOEXPR field for these rows is ‘NODX’, which is intended to mean the absence of a map. These rows were erroneously assigned a rel/rela combination of RQ/mapped_to in MRMAP, whereas they should have the rel ‘XR’, which means ‘map to nothing’.
  • MAPSETCUI C3264360 has 85 TOEXPR values that have an erroneous trailing decimal period. Example: C3264360|ICD10CM|||AT146354901||M21.41||M21.41|SDUI|||RQ|mapped_to|15206||734.|SDUI|||||||||

Solution: These errors will be corrected in the 2012AB Release.

Date Posted: May 7, 2012


Title: 2011AB Database Load Script Error

Problem: Term type list (TTYL) field length is not sufficient.

Solution: Edit the corresponding table creation script (e.g. oracle_tables.sql or mysql_tables.sql) and change the length of the TTYL field to 400 instead of 300. For Oracle users, also edit the MRSAB.ctl file and set TTYL field to char(400) instead of char(300).

Date Posted: December 1, 2011


Title: MeSH Data Error

Problem: An invalid MeSH tree number, D12.776.157.057.000, for MeSH ID D058927 appears in the MRSAT file (both ORF and RRF formats). Its CUI is C2936832.

Solution: The correct tree number is D12.776.157.057.001. This error will be corrected in the 2012AA Release.

Date Posted: November 16, 2011


Title: Encoding error causes display problems for MedlinePlus definitions

Problem: Characters in MedlinePlus definitions are not displayed correctly in MRDEF.RRF.

Solution: This error will be corrected in the 2011AB Release.

Date Posted: June 16, 2011


Title: SPECIALIST Lexicon & Lexical Tools installation progress bar reads beyond 100%

Problem: When installing the SPECIALIST Lexicon & Lexical Tools on various platforms, the progress bar reads beyond 100%. This is a display bug that does not affect output or subset completion.

Solution: This error will be corrected in the 2011AB Release.

Date Posted: May 5, 2011


Title: Precedence Filter Bug and Missing Rows in MRRANK.RRF

Problem: When copying an old configuration (.properties) file from a previous MetamorphoSys release to re-use in the current release, the Precedence Filter may not pick up new term types added between the current release and the last release.  This leads to missing rows in MRRANK.RRF.

Solution: This error will be corrected in the 2011AB Release. The workaround is to point ‘default_subset_config_uri’ in your configuration file to ‘%MMSYS_HOME%\config\2011AA\user.a.prop’.

Date Posted: May 5, 2011


Title: Subset creation progress bar reads beyond 100%

Problem: When creating a subset on various platforms, the progress bar reads beyond 100% (into the millions). This is a display bug that does not affect output or subset completion.

Solution: This error will be corrected in the 2011AA Release.

Date Posted: November 22, 2010


There are no known problems for the 2010AA release. Please send any issues or concerns to NLM Customer Service.


Title: OMIM Data Errors


  • Two HT terms were misspelled in the file received from the source. The terms GENITOURINIARY and NEPLASIA were placed under the RHT, adding two false axes to the hierarchy. Both of these terms are also present in their correctly spelled forms, GENITOURINARY and NEOPLASIA.
  • The OMIM term “Behavioral/psychiatric manifestations” (UMLS CUI C1854373) has two erroneous variant terms, “Psychiatric/behavioral manifestations” and “Behavioral/psychiatric Manifestations”.

Solution: The corrected terms will be present in the next version of OMIM in the Metathesaurus.

Date posted: November 3, 2009


Title: LNC215 to CPT2005 Mappings Bug

This bug affects the following Metathesaurus files: MRCONSO.RRF, MRSAT.RRF, MRMAP.RRF, MRRANK.RRF

Problem: MRCONSO.RRF contains Mapset metadata CUIs that describe mappings in the UMLS. These CUIs are all assigned the term type (TTY) 'XM'. The CUI 'C1704201' contains the term 'LNC215 to CPT2005 Mappings' which is the only term in this CUI. In 2009AA, this term was erroneously assigned an NLM 'MTHU' code that was shared by an term with a higher ranking term type (MRRANK.RRF). Due to the error, all of the rows in MRMAP.RRF that contain the data for the 'LNC215 to CPT2005 Mappings' are attached to the wrong CUI ('C2599619' rather than 'C1704201'). All of the attributes associated with this map in MRSAT.RRF are also attached to AUI 'A16416485', which belongs to CUI 'C2599619'

Solution: If you are a user who is interested in using the LNC215 to CPT2005 mapping from MRMAP.RRF, please use the 2008AB release, because the actual content for the map does not change from release to release. NLM will correct the error for the 2009AB UMLS release.

Date posted: May 22, 2009


Title: SQL Load Script produces errors related to ' \|' character sequence

The following applies to users attempting to load the 2008AB RRF data into a MySQL database using the MetamorphoSys-generated MySQL load scripts.

Problem: Due a '\|' character sequence in the 2008AB data, the following MySQL error message is displayed while loading RRF data into a database: Warning (Code 1264): Out of range value adjusted for column 'SRL.'


  1. Open up the mysql_tables.sql file in your MetamorphoSys output directory.
  2. Change the following line from:
    • load data local infile 'MRCONSO.RRF' into table MRCONSO fields terminated by '|' lines terminated by '\n'  to the following:
    • load data local infile 'MRCONSO.RRF' into table MRCONSO fields terminated by '|' ESCAPED BY '' lines terminated by '\n'
  3. Save and close the file, then re-run the script.

Title: MetaMap NLP View label missing from Content View Restrictor Window

Problems: On the Restrict Searches and Views Option, Content View Restrictor screen, the name of the third content view (MetaMap NLP View) is missing.

Solution:This error will be corrected in the 2009AA release.

Date posted: November 17, 2008


Title: Advanced Suppressibility Options Error

Problems: When using Advanced Suppressibility Options to remove suppressible term types from a customized Metathesaurus subset, MetamorphoSys may not have removed all of the appropriate rows/data from the customized Metathesaurus MRHIER.RRF file.

Solution:Log in to the UMLSKS and download the updated 2008AB UMLS Release files. Note: The Build Date of the correct version of MetamorphoSys is 2008_11_20_06_34_04 (located in Help --> About MetamorphoSys, in the Welcome to MetamorphoSys window).

Date posted: November 24, 2008

Title: Non-ASCII UTF-8 dash characters in 5 RxNorm, MTHSPL CODES not removed by MetamorphoSys Output Option


Who is affected? Users who
 (1) include RxNorm or MTHSPL data in their customized Metathesaurus subsets, and who also
 (2) use the Output Option in MetamorphoSys to exclude non-UTF-8 characters from their subset

MetamorphoSys fails to remove the following non-ASCII UTF-8 dash characters in the CODE field in the following 5 rows in MRSAT (2007AB):
C0716197|L6401119|S7339522|A11769224|AUI|0025–1961|AT69829041||SPL_SET_ID|MTHSPL|0B0BA593-FE54-456C-A3D7-651C 50036E3E|N||

It fails to remove the non-ASCII UTF-8 dash in in the CODE field of one MRCONSO row:

C0716197|ENG|S|L6401119|PF|S7339522|Y|A11769224||||MTHSPL|DP|0025–1961|Metronidazole 750 MILLIGRAM In 1 TABLET ORAL TABLET, FILM COATED, EXTENDED RELEASE [Flagyl ER]|0|N||

The dash character in these rows is not an ASCII dash, but rather the UTF-8 dash: 
0x2013|U+2013|EN DASH|General Punctuation|1


The Unicode character U+2013 is represented in UTF-8 as a sequence of the following 3 bytes (in octal):
\342, \200 and \223.

Use the following perl script to make the change in the appropriate file:
perl -ne '{s/\342\200\223/-/g;print}' MRCONSO.RRF
perl -ne '{s/\342\200\223/-/g;print}' MRSAT.RRF

These errors will be corrected in the 2007AC release.

Title: Bad LOINC Relationship data in early release

Relationship data was incorrect in an early edition of the 2007AA release. Users who downloaded the release prior to the official announcement will find incorrect LOINC mapped-to relationships in the file MRREL.

The information has been corrected in the official 2007AA release. Users should download these files which were made available on 1/29/07.

Date posted: January 30, 2007


Title: Oracle Load Script produces errors related to Japanese language sources

Oracle users receive errors when trying to load the file RXW_JPN.RRF.

The log file will report a series of errors like the one below:

Record 6171: Rejected - Error on table MRXW_JPN, column WD.
Field in data file exceeds maximum length

The error occurs because Oracle interprets the length of the WD column of the MRXW_JPN table in terms of BYTE semantics, instead of CHAR semantics.  To force SQL*Loader to handle this properly, the MRXW_JPN.ctl SQL*Loader control file can be edited to include this line:

characterset UTF8 length semantics char

Thus, the complete MRXW_JPN.ctl file would be as follows:

options (direct=true)
load data
characterset UTF8 length semantics char
infile 'MRXW_JPN.RRF' "str X'7c0a'"
badfile 'MRXW_JPN.bad'
discardfile 'MRXW_JPN.dsc'
into table MRXW_JPN
fields terminated by '|'
trailing nullcols
(LAT    char(3),
WD      char(100),
CUI     char(8),
LUI     char(8),
SUI     char(8)

With this change, the populate_oracle_db.csh script should run to completion without any errors.

Title: Oracle Load Script produces errors related to character fields

Oracle users receive errors when trying to load the file MRSAT.

Set "Truncate long fields to 3990 characters" to avoid errors in loading MRSAT rows into Oracle. "Truncate long fields..." appears on the "Output Options" tab, under "Maximum Field Length". This problem will be fixed by changing the default field length in the 2007AB Release.

Date posted: January 15, 2007


Title: MRHIER and MRSAB don't load properly in Oracle databases

Oracle users receive errors when trying to load the files MRSAB & MRHIER.


If you have already created a subset, edit the file "oracle_tables.sql" or "mysql_tables.sql" so that the TTYL field has a length of 200 (instead of 100) and the PAUI field has a VARCHAR (or in Oracle VARCHAR2) data type with length 9 (instead of CHAR(8)). If loading Oracle scripts, also edit the SQL*Loader control files "MRSAB.ctl" and "MRHIER.ctl" to accordingly set the lengths of the TTYL and PAUI fields.

Prior to creating a subset:

Edit the MMSYS/config/mrpluscolsfiles.dat file. Change the lines

TTYL|MRCOLS|varchar(100)|Term type list for a source||||06-DEC-06|
PAUI|MRCOLS|char(8)|Unique identifier for parent atom||||06-DEC-06|

To this:

TTYL|MRCOLS|varchar(200)|Term type list for a source||||06-DEC-06|
PAUI|MRCOLS|varchar(9)|Unique identifier for parent atom||||06-DEC-06|

This problem will be fixed in the 2007AB Release.

Title: Macintosh directory names with spaces

On Macintosh OS X, the name of the install directory and its parents can not include spaces; shell scripts will fail to find the current directory name, and cause this error message to appear:

cd: MMSYS: No such file or directory

Install the UMLS release files in an install directory with no spaces in its name or the names of its parents.

2006AC, 2006AD

Title: MetamorphoSys Content View Filter Tab 

1) Enabling the Content View Filter creates a blank tab. The Natural Language Processing Content View Filter is not displayed and cannot be selected.
(2) Users are unable to navigate away from the blank tab.  (Temporary and immediate solution:  Disable the Content View Filter.)

The error exists in the files MMSYS/config/mmsys.a.prop and MMSYS/config/mmsys.b.prop.

Add the lines below to the both of both files:  

gov.nih.nlm.mms.filters.ContentViewFilter.name_2=MetaMap NLP View
gov.nih.nlm.mms.filters.ContentViewFilter.description_2=It represents the strict model of data used by MetaMap.


Adding these lines will correct the error and allow users to enable a Content View Filter that correctly displays the Natural Language Processing filter. 

Date posted: November 3, 2006


Title: Advanced Suppressibility Options -->Remove Suppressible Term Types Option does not remove Term Types

Users who create an ORF subset and select one or all of the following options: Remove Source Term Type Suppressible Data, Remove Editor Assigned Suppressible Data, or Remove Obsolete Data, will find the line "Suppressible terms were included in the subset." at the bottom of their MMSYS.log file.

Solution: The error exists in the production of the log file, not in the data files. Examination of the data files will show that suppressible terms were not included in the subset, in relation to the options the user checked. (For example, if Remove Obsolete Data was checked only obsolete terms will be removed.) The error in the log file will be corrected for the 2006AD release.

Date posted: July 14, 2006


Title: In the RRF Browser, Find command does not highlight terms

On Mac, Solaris, and Linux platforms: when using the find command, found terms are not highlighted until the user moves (scrolls up or down) within the window.

Solution: The error will be corrected for the 2006AD release.

Title: Java Issues After Installing J2SE 5.0 Release 4 Update

Problem: The software update for Java 2 Platform Standard Edition (J2SE) 5.0 Release 4 for Mac OS X v10.4.5 will change the default version of Java virtual machine from Java 1.4.2 to Java 5.0. This may cause problems with MetamorphoSys.

Solution: Reset the default Java virtual machine. Instructions are available from Apple at The 2006AC release of the UMLS will call the correct JRE, regardless of the default settings.

Date posted: 5/08/06


Title: Incorrect MeSH® Relationships

Problem: In the UMLS 2006AA release available for download from 2/13/06 to 2/24/06, erroneous relationships were present in the MRREL file and duplicated in the files MRHIER, MRFILES, and MRCOLS.

Solution: A corrected release was made available for download from the UMLSKS on 3/2/06.

Date posted: 2/24/2006


Title: Problem with MRHIER.RRF References

Problem: The removal of MRCXT.RRF from the default data set for 2006AA had the unintended consequence of affecting hierarchy information in MRHIER.RRF, such that the information cannot be properly resolved by MetamorphoSys in all cases.

In particular, in cases where a source with hierarchies is selectively subsetted, a situation may result where the PTR field of MRHIER.RRF contains references to AUI values that do not exist in MRCONSO.RRF.

Scope: This will likely not be an issue for the majority of users. In the event that a user's configuration causes MetamorphoSys to either keep or remove sources in their entirety, this problematic data condition does not arise.

There are four known ways in which this condition might occur. Each involves removing parts of sources that contain hierarchies without removing the entire source and operating with an input set that does not contain MRCXT data:

  1. Using the "remove UTF8" option in the output handler configuration panel in conjunction with a source list that included sources with UTF-8 characters and a hierarchy
  2. Selecting "remove suppressible data" from the suppressible termgroups advanced options and choosing suppressible termgroups from among the atoms of a source that contains hierarchies
  3. Using the SampleMetaFilter (very rare)
  4. Using a user-created filter that selectively removes atoms from sources with hierarchies (very rare)

The first two situations will by far be the most common.

When using the "remove UTF8" condition in conjunction with a Source List configuration that includes sources with UTF-8 characters, the resulting MRHIER.RRF will contain this data condition. The set of sources containing UTF-8 characters (and contexts) includes:


When selecting term types to be suppressible that participate in contexts and using the advanced options "remove suppressible data" option, the resulting MRHIER.RRF will contain this data condition.

Following is a sample problematic MRHIER.RRF entry that occurs when the user configures MetamorphoSys to "remove UTF-8" and to keep all sources.


In this example, AUIs A7452688, A7452689, and A7455821 are not found in MRCONSO.RRF.

Here is another example:


In this case, AUI A7525302 is not found in MRCONSO.RRF.

Solution: There is a work-around for this problem, albeit a time-consuming one. As indicated above, this problem results when the input set does not contain MRCXT.RRF data. The presence of MRCXT.RRF on the input side would guarantee output data free of this data condition.

The user should take the following steps:

  1. Generate an output set using the desired configuration, making sure not to select options matching any of the four conditions described above. The output subset should then contain all of the hierarchy data for the set of sources selected for inclusion.
  2. Use the MRCXT builder to create a MRCXT.RRF file matching the MRHIER.RRF file.
  3. Use the first output set (including MRCXT.RRF) as the input and create a second output, this time using the options that created the initial problem. This second output set should be what the user is looking for.

So, consider the case where the user wanted the "keep everything" subset with the "remove UTF-8" option selected. In order to achieve this via the work-around, the user could take the following actions:

  1. Configure the Source List to include all sources.
  2. Ensure that "remove UTF-8" was NOT checked in the output handler configuration.
  3. Generate the output set.
  4. Run the MRCXT Builder to generate a full MRCXT.RRF file.
  5. Re-configure MetamorphoSys to point to the set of data generated in #1-4. Again include all sources but this time make sure that "remove UTF-8" IS checked.
  6. Generate a second output set. This one will contain correctly resolved MRHIER.RRF data.
  7. Remove the first set of output files (unless additional subsets are to be made from it).

A more technically sophisticated user could also use a perl script like the one below to manually remove the unwanted MRHIER.RRF entries from their subset.


open (MRCONSO,"MRCONSO.RRF") || die "Could not open MRCONSO.RRF : $! $?\n"; while (‹MRCONSO›) {
  split /\|/;
  $auis{$_[7]} = 1;
close (MRCONSO);
open (MRHIER,"MRHIER.RRF") || die "Could not open MRHIER.RRF : $! $?\n"; while (‹MRHIER›) {
  split /\|/;
  $ptr = $_[6];
  @ptr_auis = split /./, $ptr;
  $missing = 0;
  foreach $aui (@ptr_auis) {
     unless ($auis{$aui}) {
       $missing = 1;
  print "$_\n" unless $missing;
close (MRHIER);

The output of this script would be a corrected MRHIER.RRF file.

Title: LSN Attribute Incorrectly Defined

Problem: The LSN attribute is incorrectly defined as "LOINC short name".

Solution: The correct definition for this attribute is "LOINC Spanish name". The offical documentation is correct and can be accessed at This issue will be resolved in the 2006AB release.

Date posted: 2/13/2006


Title: ATN Field Too Short in the ORF File MRCOLS

Problem: When generating an ORF subset with the database load script option, the ATN field is set to 20 chars instead of 50.  Any sources that have ATN values greater than 20 that are loaded into a database using one of our scripts produces an error (data is longer than the field length).

Solution: After generating subset and the load script, edit the load script to make ATN field 50 chars. This issue will be resolved in the 2006AA release.

Date posted: 11/30/2005


Title: TS Fields in MRCON Not Properly Computed for Editor Suppressed Atoms

Problem: When generating an ORF subset from ORF input, the TS fields in MRCON are not properly computed for editor suppressed atoms.

Solution: This issue will be resolved in the 2006AA release.

Date posted: 11/30/2005


Title: MeSH Attribute Information Incorrectly Represented

Problem: The data problem reported on 7/19/2005 has been fixed. In the original 2005AB release (release date 20050615), some data in the following MeSH attributes were incorrectly represented in the Metathesaurus files MRSAT and MRREL: 

MeSH Attributes

Attributes from other sources, and MeSH data in other Metathesaurus files, including MRCONSO, MRDEF, MRSTY, and MRHIER, were unaffected.

Solution: Licensees who use MeSH attribute data in their research or applications should use the corrected 2005AB UMLS release. The corrected 2005AB UMLS release carries the release date of 20050718. Release date is included in the release.dat and mmsys.log files.

Date posted: 7/26/05


Title: MetamorphoSys Errors Associated with Mac OS Tiger

Problem: We have found issues in the most recent Tiger update (10.4.2) that may cause new problems for users, including application crashes. We are investigating and expect Apple to remedy these issues. One specific problem: Mac OS Tiger users receive an error message stating "Resources temporarily unavailable" when running MetamorphoSys.

Solution: This error has been corrected in the 2005AC release of the UMLS. If you must use an older version, close all unnecessary applications. Macintosh Tiger users (OS X 10.4) are reminded to quit all other applications (including dashboard widgets) to avoid the Mac "resource temporarily unavailable" error.

Problem: MD5 files created using Windows are not the same as MD5 files created on other operating systems.

Solution: There is no solution at this time. This problem will be corrected in the 2005AC release.

Date posted: 6/15/05


Title: Disk Full Errors Are Not Detected and Reported in MetamorphoSys

Problem: In some circumstances disk full errors are not properly detected. MetamorphoSys may appear to complete correctly but files are corrupted. Files may include truncated lines or null characters inserted into the data.

Solution: Users must be certain that they have adequate disk space before using MetamorphoSys.

Title: Invalid Data in NDDF Update; Also Affects RxNorm Subsets

Problem: There are serious errors in the NDDF update in 2005AA that affect not only NDDF in the Metathesaurus, but also RxNorm. Drug data that was added to the Metathesaurus from the November NDDF update are correct, but over 100,000 NDDF drug names already in the Metathesaurus were incorrectly marked as obsolete. NDDF data, as a separate source, and within the RxNorm subset, should not be used, or should be used with extreme caution.

Solution: A new RxNorm Cumulative Release File, including corrected NDDF data, will be available in late February or early March.
NDDF will be corrected in the UMLS 2005AB release, scheduled to be available in April 2005.
See also: RxNorm Cumulative Update.

Date posted: 2/8/2005


Title: RxNorm Cumulative Update: Non-Matching Codes for RxNorm Atoms

Problem: The RxNorm Cumulative Update of 11/17/2004 contains non-matching codes for RxNorm atoms. This update is based on the 2004AC release of the UMLS, but contains all new codes for RxNorm atoms. These codes do not correspond to previously assigned codes and the update cannot be applied to existing RxNorm data.

Solution: RxNorm data will be resynchronized with the 2005AA release, updated with SNOMED CT drug data, and the full and corrected Cumulative RxNorm will be released in late February or early March.

Date posted: 2/8/2005


Title: Missing Codes in Spanish and Portuguese Translations of MeSH 2005 (MSHSPA and MSHPOR)

Problem: For 2005AA, the Spanish and Portuguese translations of MeSH 2005 (MSHSPA and MSHPOR) do not include the MeSH Descriptor Number in the CODE field in MRCONSO.RRF (MRCON in ORF).

Solution: Problem will be corrected in 2005AB.

Date posted: 1/18/2005

There were no known issues for 2004AC.


Title: ORF Database Load Scripts for Those Who Downloaded 2004AB Before Friday, July 23rd

Problem: The Original Release Format (ORF) MySql and Oracle load scripts for indexes are missing column names.


  1. Manually insert column names into script for indexes
  2. Download and unzip the file (64364251 bytes or 61 MB), then re-run MetamorphoSys to recreate your data

Date posted:7/27/2004


Condition: User selects RxNorm subset from the initial Default Subsets list, then disables the filter by unchecking the box on the RxNorm Output Options tab.

Bug: Unchecking the box does not disable the filter. The RxNorm filter is applied regardless of the state of the checkbox.

Temporary Fix for 2004AB: Do not pick RxNorm filter on the Install menu and then attempt to deselect this option on the RxNorm Output Option tab.

Date identified: 7/20/2004

Date fixed: To be corrected in the 2004AC release.
