I need human gff3 file of non coding smallRNA annotation (e.g. miRNA, piRNA, lncRNA, siRNA...).
I have found this gtf file: ftp://ftp.ensembl.org/pub/current_gtf/homo_sapiens/ (Homo_sapiens.GRCh38.89.chr.gtf), in which I am sure that there are both miRNA and lncRNa. I looked into gene_name but I didn't find piRNA, siRNA...
Are there these smallRNA in that gtf file? Where can I find the list of gene_name of smallRNA reported in the gtf file?
Moreover, how can I extract only smallRNA from that list in order to use it to annotate my alignment?
Thank you in advance
