The NIH Comparative Genomics Resource (CGR)
The National Institutes of Health (NIH) Comparative Genomics Resource (CGR) is a multi-year National Library of Medicine (NLM) project to maximize the impact of eukaryotic research organisms and their genomic data resources to biomedical research.
BLAST
BLAST® finds regions of similarity between biological sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance.
Comparative Genome Viewer (CGV)
The Comparative Genome Viewer (CGV) tool allows you to compare two genomes based on assembly-assembly alignments provided by NCBI.
Foreign Contamination Screen (FCS)
The NCBI Foreign Contamination Screen (FCS) is a tool suite for identifying and removing contaminant sequences in genome assemblies. Contaminants are defined as sequences in a dataset that do not originate from the biological source organism and can arise from a variety of environmental and laboratory sources. FCS will help you remove contaminants from genomes before submission to GenBank.
Genome Data Viewer (GDV)
The Genome Data Viewer (GDV) supports the exploration and analysis of NCBI-annotated and selected non-NCBI annotated eukaryotic genome assemblies. Currently, assemblies from over 1600 organisms are available.
NCBI Datasets
NCBI Datasets is a new resource that lets you easily gather data from across NCBI databases. Find and download gene, transcript, protein and genome sequences, annotation and metadata.
GenBank
GenBank® is the NIH genetic sequence database, an annotated collection of all publicly available DNA sequences. GenBank is part of the International Nucleotide Sequence Database Collaboration, which comprises the DNA DataBank of Japan (DDBJ), the European Nucleotide Archive (ENA), and GenBank at NCBI. These three organizations exchange data on a daily basis.
The NCBI Submission Portal
NCBI's Submission Portal allows you to submit your data to the world's largest public repository of biological and scientific information.
RefSeq
The NCBI Reference Sequence Database (RefSeq) is a comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein.
Sequence Read Archive (SRA)
Sequence Read Archive data, available through multiple cloud providers and NCBI servers, is the largest publicly available repository of high throughput sequencing data. The archive accepts data from all branches of life as well as metagenomic and environmental surveys. SRA stores raw sequencing data and alignment information (if submitted) to enhance reproducibility and facilitate new discoveries through data analysis.
PubMed
PubMed® comprises more than 34 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full text content from PubMed Central and publisher web sites.
PubMed Central (PMC)
PubMed Central® (PMC) is a free full-text archive of biomedical and life sciences journal literature.
