Summary
When interfaces.utility.Function is used in combination with JoinNode, report.rst shows that function_str is <undefined>. With normal nodes, everything is OK. I'm not sure, but I have a suspicion that it also affects caching. Here's an example Node and a part of its report:
combine_plots = nipype.JoinNode(interface = util.Function(input_names = ['data_list','subject_id'],
output_names = ['out_plot', 'out_data'],
function=combine_plots_fun),
name = 'combine_plots', joinfield = ['data_list'],
joinsource='samples_pars',
run_without_submitting = True)
Node: combine_plots (utility)
