Hi there, I wanted to extract the TSS up-stream region of each gene up to the end position (TTS) of the nearby gene. I only known the promoter function, but it seems can not deal with this problem. I could only get the GenomicRange object of all genes from the gtf file by the following codes:
txDB <- makeTxDbFromGFF("test.gtf") genes <-genes(txDB)
How to obtain my desired region for each gene?
