This directory contains GTF files for the main gene transcript sets where available. They are
sourced from the following gene model tables: ncbiRefSeq, refGene, ensGene, knownGene

Not all files are available for every assembly. For more information on the source tables 
see the respective data track description page in the assembly. For example:

Information on the different gene models can also be found in our genes FAQ:


The files are created using the genePredToGtf utility with the additional -utr flag. Utilities
can be found in the following directory:

An example command is as follows:
    genePredToGtf -utr hg38 ncbiRefSeq hg38.ncbiRefSeq.gtf
