Hello! 1 month ago i completed a transcriptome study. While making the normalization step, i used featurecounts. My featurecounts code was;
featureCounts -a Beta_vulgaris_ncbi.gtf -g transcript_id -o results.txt
The gtf file downloaded from NCBI database. I wanted the transcript_id but my result table column says gene_id. I did not realize that until yesterday. Now i am trying to make annotation with biomaRt and i am stuck. I dont know which filter i will use in biomaRt because i dont know if i have gene_id or transcript_id. Tried both filters and non of them worked. So how can i figure it out that what kind of ID numbers they are..
