What I am trying to do is, instead of having to select the genome from a drop down that points to the loc file, to take the metadata.dbkey attribute of an input file and use it to select the genome. I want to avoid having a user of my workflow select a genome n times in each step of a workflow. Attached is a sample cufflinks_wrapper.xml and gtf_indices.loc file.

With regards to GATK, I want to edit the tools that are in the broad best practices workflow.

Subject: Re: Modifying the GATK wrappers to pick genome infomration from bam/sam dbkey attribute

Hi Ilya,

You can validate dbkeys using validators including metadata, dataset_metadata_in_file/data_table, unspecified_build and others. 

Could you clarify what GATK tools you are trying to modify and exactly what you are trying accomplish? A complete example xml file, and any additional files (e.g. *.loc) would need to be provided to give you direction.

Thanks for using Galaxy,

Dan

Hi Dan,

I want to modify the wrappers to get genome information from the bam/sam attribute. I did this for the tophat/cufflinks wrappers. I add another option to select genome called attribute and then I pass $bam.metadata.dkey in the command line (see example below). Is this something you might be interested in? Can you suggest an alternative way to do this? My only concern is my inability to validate that the $input.metadata.dbkey exists.

Thanks,

Ilya

See example below.

                #if $reference_annotation.annotationSource.reference_annotation_file == "indexed":

                   -G "${ filter( lambda x: str( x[0] ) == str( $reference_annotation.annotationSource.indices ), $__app__.tool_data_tables[ 'gtf_index' ].get_fields() )[0][-1] }"

                #else:

                     #if $reference_annotation.annotationSource.reference_annotation_file == "attribute":

                         -G "${ filter( lambda x: str( x[0] ) == str( $input.metadata.dbkey ), $__app__.tool_data_tables[ 'gtf_index' ].get_fields() )[0][-1] }"

                     #else:

                         -G "${reference_annotation.annotationSource.ownFile}"

                     #end if
