: Best for most users. You can download the full genome as a single file ( mm10.fa.gz ) or as individual chromosomes. UCSC also provides a compressed .2bit version, which is faster for certain command-line tools like twoBitToFa .
For large files, using the command line is more reliable than a web browser. Use wget or rsync to pull the files directly to your server: mm10 fasta file download
The mm10 assembly (released in 2011) is the 10th version of the mouse genome from UCSC and corresponds to from the Genome Reference Consortium. Although mm39 (GRCm39) is the latest version and features fewer gaps and improved contiguity, many labs stick with mm10 to maintain compatibility with older datasets or specific software pipelines that have not yet updated their native indices. : Best for most users
Different providers offer the mm10 sequence in various formats to suit specific computational needs: For large files, using the command line is
You can download the mouse genome FASTA files from major bioinformatics repositories like the UCSC Genome Browser , NCBI , and GENCODE . While the newer mm39 (GRCm39) assembly exists, mm10 remains widely used for consistency in longitudinal studies and historical data comparisons. Where to Download mm10 FASTA Files
: This is the "naked" sequence with no masking. It is the standard choice for building indices for tools like BWA , Bowtie2 , or STAR .
