Hello, I've been using rtracklayer to make bedGraph files from RLElist objects (which works wonderfully). e.g. a little pseudo code:
ip <- RLElist(myBigFatChipSEQpipelineResults) export(ip, "ip.bedGraph") I then convert the bedGraph files to bigWigs using the bedGraphToBigWig command line utility from UCSC. The bigWigs are binary versions of wig or bedGraph files that are created from wig or bedGraph data that does not have an initial track line. However, rtracklayer puts an initial "track line" in each file by default, that has to be removed for bigWig creation. My question is: how do I suppress having a track line in exported bedGraph data? -Chris sessionInfo() R version 2.11.1 rtracklayer_1.8.1 _______________________________________________ Bioc-sig-sequencing mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/bioc-sig-sequencing
