Kindly help how to solve this issue?

Hi @sajjadasaf, I am not a maintainer, but happy to help troubleshoot. I reviewed a copy of the log file you attached and found the following error message:

[error] In FixFasta, two references with the same name but different sequences: unassigned_transcript_938. We require that all input records have a unique name up to the first whitespace (or user-provided separator) character.

Based on the error message, it looks like you might have duplicate header sequences in your FASTA file, which isn't allowed. I would recommend addressing this issue and then rerunning the pipeline.

Please let us know if this resolves your issue.

[sajjadasaf]

Thank you very much for your reply. Actually I am using genome downloaded from Ensemble and i am unable to find any duplicated sequences here. Should we make changes in GTF file before running this pipeline?

If there are no duplicated sequences, I don't think changing the GTF file should be necessary. Happy to try reproducing the error using the same reference and gtf file. Would you mind sharing which reference genome and version was used from Ensembl?
