Kind of a naive question, but is the mm10 genome on galaxy the same as GRCm38.ERCC mouse genome?

Hello,

The mouse mm10 genome indexed at Galaxy Main http://usegalaxy.org is sourced from UCSC based off of NCBI's GRCm38. These are the credits: http://genome.ucsc.edu/goldenPath/credits.html#mouse_credits

While GRCm38 from NCBI is technically the same build (in terms of sequence content), the sequence identifiers will differ between the original at NCBI and what UCSC produces. Then ERCC RNA data is an extra layer of annotation added to base genomes available at certain sources (GEO and Ensembl host these, I believe, and perhaps others). The source mm10 from UCSC used at Galaxy Main does not include this content.

If you wish to use a different genome version for mouse than what is available at Galaxy Main, a local/cloud Galaxy can be used with a genome added with a Data Manager (from any source) or you can try using the Custom Genome feature at Galaxy Main - just be aware that using such a large genome as a custom genome may create jobs that run out of memory.

It is important to use the same exact reference genome version for all steps in an analysis or unexpected results are to be expected.

Thanks, Jen, Galaxy team

I didnot find mm10 Fasta format in data library. Could you specify, How can I add ref.genomes to the history panel (similar to adding .gtf files from galaxy library)?
