I want to draw only one gene model in one genomic range ( some genes have overlapping ranges).
How can I do it using GeneRegionTrack in the Gviz package?
I read the tutorial,
" Alternatively, one can provide the Ensembl trancript or gene id via the transcript or gene arguments, or an Entrez id via the entrez argument. In all of these cases the constructor will also fetch models for other genes that overlap the same region. If that is not desired one needs to provide an explicit Biomart filter.
biomTrack <- BiomartGeneRegionTrack(genome = "hg19", name = "ENSEMBL", symbol = "ABCB5") plotTracks(biomTrack)
How can I specify the filter here?
