Determine chromosome names in reference genome already in Galaxy?

I would like to find out the names of chromosomes contained in one of the Galaxy-provided reference genomes.

Is there a quick and easy way to do that?

If it’s brought into Galaxy via cvmfs you can check the actual reference files at http://datacache.galaxyproject.org/.

If you’re looking for a (limited) tool-based solution, you could try
https://usegalaxy.org/root?tool_id=toolshed.g2.bx.psu.edu/repos/wolma/mimodd_main/mimodd_info/0.1.9. It works only on the actual fasta reference genomes and does not let you inspect indices for tools though.

You can also run some simple test mapping against the genome and review the BAM output header. Try a Samtools or Picard stats tool to parse much header information into a tabular report.

Or, if a UCSC-sourced genome, review directly here: https://genome.ucsc.edu. All genomes from this source are exact replicas of the soft-masked genome version. Chromosomes name are in the file chrominfo available from the Table Browser.
