Hi @Vu_Ngo,

The error message points on issue with the annotation file and the job setup. featureCount is usually used for gene expression projects, while your annotation file is for peaks. Check this topic:

> Hi Igor, Thanks for the follow up, I repeated the steps, and this time, I did not use any trimming tools. Please use this link to access the workflow; [url: https://usegalaxy.org/u/seraph2/h/rna-seq](https://usegalaxy.org/u/seraph2/h/rna-seq) Seraph

(ignore my typos, like axon instead of exon)

If this does not help, maybe share the history using the following procedure: click at History Options (three horizontal bars icons) in the top right corner of the History panel; select Share or Publish; in the middle window make the history accessible, copy and paste the link here.

Kind regards,  
Igor
