Dear Bioconductor mailing list, If I have some CSV data in a file like this : Probe Set ID,Alignment Start,Alignment End,Strand,Gene Symbol 1380054_at,167415761,167416381,+,Phactr3 1368499_at,167437521,167502083,-,Sycp2 1378270_at,167504376,167504858,+,Ppp1r3d 1373656_at,167505691,167506150,-,Ppp1r3d 1395392_at,167508167,167508749,-,Ppp1r3d ... 1392332_at,170985205,170985581,+,Myt1 1375916_at,171012460,171013368,+,Pcmtd2 1374454_at,171013932,171014583,+,Pcmtd2 1398875_at,171021421,171022475,+,Polr3k ... and I want to make a nice graph showing where each probe set aligns along the region between 167400000 bp and 171000000 bp, where would be a good place to start? I guess I would have to use a lot of low level plotting functions, but I would need to create a blank graph to begin with. what would be cool would be a thick vertical line on the left representing the chromosome and vertical lines to the right showing each probeset's alignment to the chromosome, with each line labeled by the ProbeSetID, gene Symbol and strand. Any help would be greatly appreciated. Richard [[alternative HTML version deleted]]

I'd thumb through the GenomeGraphs package (particularly its vignette): http://www.bioconductor.org/packages/release/bioc/html/GenomeGraphs.ht ml Those plots are the transpose of what you are looking for (they're "horizontal" where it sounds like you want yours to be "vertical"), but maybe it'd do. -steve -- Steve Lianoglou Graduate Student: Computational Systems Biology ?| Memorial Sloan-Kettering Cancer Center ?| Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact
