No, I am not subclassing from Tabular. But when I do, it suddenly works. Thanks loads Dan! cheers, — Jorrit Boekel Proteomics systems developer BILS / Lehtiö lab Scilifelab Stockholm, Sweden On 07 Nov 2014, at 19:07, Daniel Blankenberg <dan@bx.psu.edu> wrote:

Hi Jorrit,

Are you subclassing your tsv datatypes from tabular?

If you can post your tool xml and datatype_conf.xml additions then we should be to provide more assistance.

Thanks for using Galaxy,

Dan

Dear list,

I tried to make a tool that takes tsv input and have some data_columns selection parameters in the xml definition. It seems to work, but I get ‘invalid option was selected’ in the browser interface for each of the data_columns. No logging errors or stacktraces.

Digging a bit, I found out that the legal_values of the ColumnParameter (in lib/galaxy/tools/parameters/basic.py ) is empty. It is returned empty by get_column_list when this does if not dataset.metadata.columns: on line 1184 of the above mentioned file.

Now I’m a bit at a loss, how do I set these columns, or where are those columns set on the metadata? Is it stored, generated from the input file? My files are not official formats, just tsv subclasses.

I’m on changeset 14567:007f6a80629a in galaxy-dist.
