Display column headers in data_column parameter
Dear Galaxy-Dev Team, is it possible to display the headers of the columns which can be selected in a data_column parameter? Currently, only the column index (e.g., c1, c2, etc.) is displayed in Galaxy. If it would be possible to additionally display the column headers, the selection of the desired columns would be easier for the user. Is there a way to do this using the current version of Galaxy?

I completely agree that in general the UI for column parameter isn't as user friendly as it could be. The filter data UI is even worse for non-programmers, but due to its complexity and flexibility, that is harder to improve too. This was one of the things I wanted to bring up with the Galaxy team at the conference (starting tonight). Unfortunately due to the Grimsvotn Volcano's cloud of ash I won't be there. In some cases yes, Galaxy knows the column meaning. In many of my data files there is a # header line with tab separated column names, which could be detected and shown. Given there may or not be suitable column meta data, what I was picturing was an expanded column picking dialogue that could show the first few rows of data in each column (not using a simple HTML widget anymore), or simply the first value (less drastic change). So, rather than having as now something like: Pick column(s): [ ] c1 [ ] c2 [ ] c3 [ ] c4 [ ] c5 If Galaxy has names in the column meta data you might have Pick columns(s): [ ] c1 - Identifier [ ] c2 - Start [ ] c3 - End [ ] c4 - Strand [ ] c5 - Sequence Or, showing the first data entry: Pick columns(s): [ ] c1, e.g. "gi|12345678" [ ] c2, e.g. "123" [ ] c3, e.g. "456" [ ] c4, e.g. "+" [ ] c4, e.g. "ACGTACTGT..." In the final example I envision truncating very long values with an ellipsis. Both the above proposals don't require drastic changes to the HTML widget and layout. I guess we should file an enhancement issue on bitbucket: https://bitbucket.org/galaxy/galaxy-central/issues/new Peter
