I mapped my fastq files using HISAT2 on a gtf.gz file in my history, and that worked out well. When converting this gtf.gz to a BED12 format and using this bed12 file for ‘RSeQC infer experiment’, it returned ‘unknown data type’. Anyone has any idea or suggestion where things are going wrong and how to solve this?
