When I run tophat ("Tophat for Illumina Find splice junctions using RNA-seq data ), the job failed with truncated files. However, index files are available and I get exactly the same error message using built-in index or one of my history.

Tool execution generated the following error message:

Error in tophat:

Error: Could not find Bowtie 2 index files (/work/galaxy/Danio_rerio.Zv9.62.dna.chromosome.22.fa.*.bt2)

The tool produced the following additional output:

TopHat v2.0.5

In this post (http://dev.list.galaxyproject.org/tophat-for-illumina-looking-in-wrong-directory-for-bowtie2-indexes-tt4658609.html#none), the solution isn't found.

Do you have any idea,
