Hi, In "cuffdiff_wrapper.xml", there are three outputs associated with CDS: <data format="tabular" name="cds_exp_fpkm_tracking" label="${tool.name} on ${on_string}: CDS Expression FPKM Tracking"/> <data format="tabular" name="cds_fpkm_tracking" label="${tool.name} on ${on_string}: CDS FPKM tracking"/> <data format="tabular" name="cds_diff" label="${tool.name} on ${on_string}: CDS diff"/> Based on the naming convention of the other outputs (and the output files from cuffdiff), I think the label of the first one should be renamed to "CDS Expression" only (assuming the relevant input file "cds_exp.diff"). -gordon
