I'm looking at some total RNA-Seq data and I'd like to get a quick look at the read distribution across "gene_type", according to Gencode annotations. Briefly, Gencode GTF files (at least for hg38) include annotations for the "gene_type", which identifies whether the region is protein coding, lincRNA, miRNA, etc. I'd like to know what percentage of reads originate from each type. RSeQC and RNA-SeQC seem to offer similar features (e.g., by exon, intron, UTR, etc.), but I don't think either provides by "gene_type".
Anyone know of existing software that will do this? I was planning to modify RSeQC read_distribution.py, but that works from BED file annotations (i.e., doesn't have "gene_type" annotations). RNA-SeQC doesn't provide source code. I could de-compile it and modify, but I don't see a specific license.
I appreciate your help.
