Hi all!

Sorry if this is a very simple question but I was wondering what is the easiest way to create a BED file of genes of interest from a GSEA gene set? For context, I would like to use computeMatrix (followed by plotHeatmap) of the deeptools toolkit to plot ChIP-seq signal within the region of genes within a specific GSEA gene set. Thank you in advance everyone!

What exactly is the question? Do you need code to make a BED file, and if so based on what? Gene symbols, coordinates of peaks? Please add details.

I would like to use deeptoolsMatrix to plot ChIP signal within the TSS of my genes of interest; my genes of interest being PRC2 targets. So if I have a set of genes from GSEA (e.g. https://www.gsea-msigdb.org/gsea/msigdb/cards/BENPORATH_PRC2_TARGETS) which provides a list of all the genes and their gene symbols and Entrez ID's, is there anyway I can quickly use this information to create a BED file containing all the genes and their coordinates?

Download an annotation file (.gff3 file type, for example) and merge the two data frames by column in R, for example performing an inner_join.
