Hello, I have a workflow that I've tried to share both with users and via link. Trying to use either of these methods to access the shared workflow results in a Server Error. paster.log reports: File '/home/galaxy/galaxy_dist/lib/galaxy/tools/__init__.py', line 795 in visit_inputs callback( "", input, value[input.name] ) KeyError: 'referenceGenome' referenceGenome is a param from one of my tool's xml configuration file. Here is the relevant section: <param name="referenceGenome" type="select" label="Reference Genome"> <options from_file="soap_indices.loc"> <column name="name" index="1"/> <column name="value" index="2"/> </options> </param> soap_indices.loc only contains one line currently ecoliU00096 E. Coli U00096 /home/galaxy/galaxy_dist/soap_indices/ecoli_U00096.fasta.index I'm confused as to why I am getting this KeyError, but I suspect that perhaps I have set up my .loc file incorrectly? Any help would be greatly appreciated. Cheers -- Branden Timm Great Lakes Bioenergy Research Center btimm@glbrc.wisc.edu
