What is the difference between GRCh and hg? I have small RNA interaction data with genome like below and they have used hg19 for mapping the reads. I want to use GTF file in Ensemble which is based on GRCh. but I was wondering the hg and GRCh are the same? If not, where can I find the GTF file for the hg19?
