Hello Delong,
Duplicated GFF IDs are not permitted in reference annotation inputs for this tool suite. There are a few options.
1 - edit the file to remove/reduce the duplicates. There could be scientific consequences when doing this, so consider carefully.
2 - use another source. iGenomes is a recommended option. An added benefit is that these files contain additional attributes in the 9th field utilized by the tools, enabling full functionality. You can read about this in the "inputs" section for each tool in
the manual, I'll link it below.
The human iGenomes gtf file is already in the public Main Galaxy instance in Shared Data -> Data Libraries -> iGenomes. Or, you can download the original data at the Cufflinks web site, extract the gtf, and load where ever you are using Galaxy (local, cloud,
other public instance).

Hello,
I was doing a RNA analyse and I wished to compare the transcription and expression of two samples using a reference annotation, however this is the error message I got:

You are using Cufflinks v2.1.1, which is the most recent release.

The job goes well without the annotation reference.
The annotation file I used can be downloaded here:
ftp://ftp.sanger.ac.uk/pub/gencode/release_17/gencode.v17.annotation.gtf.gz
Can anyone help me please?
Thanks,
Delong
