Hi Marco, No problem - I originally copied the metadata access trick from one of the Galaxy dev-team's tool anyway. Maybe we need to add this to the wiki... Peter On Tuesday, January 13, 2015, Marco Albuquerque < marcoalbuquerque.sfu@gmail.com> wrote:

Hi Peter,

I was unaware of how to access metadata, that seemed to be my issue. The tool works now though!

Thanks so much,

Marco

I think the symlink approach is best, see for example the Python wrapper script I used here for "samtools idxstats",

However, you can make the link in the XML directly, see Dave's reworking of this wrapper:
