Hi Linda,
I think your parameter definition will need to send the file_name of the HistoryDatasetAssociation, something like this...
<param name="samples" type="select" refresh_on_change="true" display="checkboxes" multiple="true" label="Mark quality control samples" dynamic_options='get_column_names(amplitudes.file_name)’/>
...and then your get_column_names() method should open the file to read the headers.
Let us know if this doesn’t work.

Hi All,
I am a bit lost here.
In my xml I have the following sections:
<inputs> <param type="data" format="tabular" name="amplitudes" label="amplitude file"/> <param name="samples" type="select" refresh_on_change="true" display="checkboxes" multiple="true" label="Mark quality control samples" dynamic_options='get_column_names(amplitudes)'/> </inputs>
<code file="dynamic_options.py" />
In my dynamic_options.py script, I want to parse the headers from 'amplitudes' file and show them in the checkboxes section.
My problem seems to be the following.
In python, amplitudes is a galaxy object: <galaxy.model.HistoryDatasetAssociation object at 0x7f4fc020a210>
How do I parse/access this file to get the headers?
It seems to be partly the same problem as asked last week in this conversation: http://dev.list.galaxyproject.org/Question-about-using-dynamic-options-and-r...
Thanks! Linda
