It is noticed that Galaxy/GATK indexes reference fasta & dbSNP file everytime 
when it runs. Re-indexing takes time (~10min), hence it affects overall run 
time when it use for multiple times. However, this could be avoided by reusing 
the available index. Here is the snapshot of the log:

Do we have any option/alternate in Galaxy to avoid this re-indexing at /tmp, as 
I have already built the index for reference and dbSNP.

Look forward to any suggestions.
