A number of tools such as Stringtie don’t accept files from “local data” .loc files so I’m trying to create a generic Input tool that presents the user with the dropdown of a specified .loc file and pass it to the downstream tool. For instance, we have a list of Reference Annotation files that we can pass to Stringtie. The problem is that if the file is compressed, the downstream tool doesn’t recognize that it is compressed because all it can see is filename.dat.
Does there already exist a way to do this? I’m taking this approach of creating a generic Input tool rather than modifying currently existing tools because there are many that do not accept Local Data and I thought it’d be faster to create a tool just for our group.
I’d prefer to use the Local Files route instead of Shared Files because the user might not always have access to the Galaxy interface (a Tripal site using Galaxy API, for instance).
The code is below. If the AA_reference_annotation.loc file lists files that are uncompressed, the downstream tools work (Stringtie), but not if they are compressed. Ordinarily, the downstream tool such as Stringtie would be able to detect if a file is compressed or not, but something with my tool and the way it gets passed makes Stringtie detect it as uncompressed.
