Let's see how that goes. gff. General Feature Format (GFF) is a tab-delimited text file that holds information any and every feature that can be. This caused featureCounts to not being able to create appropriate counts, as the gene_id was for example missing in that GTF/GFF. Note that the "Name" in output corresponds to "ID" in the original GFF3 file (based on GFF3 specification, ID for every record must be unique within a file, so this is the only identifier that can uniquely identify a specific region). library (rtracklayer) ## import the bed file bed. GFF3 was proposed by the Sequence Ontology Project in 2013 and has become the de-facto format for genome. gtf_to_gff3 Converts a GTF file into a GFF3 file Description This function converts a GTF file into a GFF3 file mantaining the feature hierarchy defined by the gene_id and transcript_id attributes.
