Hi, I am using Gviz package for plotting DMRs. So far I have successfully created attrack, itrack and Genome axis tracks. I want to create a gtrack with gene annotation information. I have used the following code grtrack <- GeneRegionTrack(DMRs, genome = "hg19", chromosome = chr, name = "Genes", transcriptAnnotation = "symbol", background.title = "brown") plotTracks(list(itrack, gtrack, atrack, grtrack))
The working DMRs file is a Grange object which I have created from a CSV. My original CSV has following information id Chromosome Start End symbol mean.mean.diff ENSG00000272438 chr1 840214 851356 TNFRSF4 -0.036783899
Executing the above I am getting the plot but instead of gene symbol every gene is named as unknown. Can anyone help with that?
