I have a history that contains datasets of various different types. I would expect when I run this workflow, however, that only the datasets in my history of type fastqillumina to appear in the drop downs for input datasets (step 1 & step 2) ... instead I see all my files from my history regardless of type (including output files of jobs that are queued... not even completed/ran) and it defaults to the output files of a job in my history that is queued but not even running/completed yet and of a type that is not supported by the bwa alignment.

Ann,

Unless I misunderstand what you're asking for, this should already be the case. For instance, if a workflow step takes in a file of 'tabular' type, only tabular files (and subtypes, including interval, etc.) should be presented as dropdowns in the list. Types such as plain text, binary files, etc., should be excluded. Are you seeing other behavior?

Thanks for using Galaxy!

I am developing a custom workflow in galaxy. I have 4 input files that need to be fed into various steps of the workflow. I would like to be able to specify a data type for the inputs such that the pre-populated drop downs are filtered to datasets of the appropriate type as well as being able to do some simple validation before the workflow begins. Is there someway to do this?

Thanks much,

Ann
