Greetings I am trying to create a custom chromLocation object from RNA-seq data aligned against the UCSC knownGene table for plotting with cPlot. The quickest way I see to do that is to assemble it from the expression results. If I look at chromLocs(buildChromLocation("org.Mm.eg")) I see (for example) $`9` 100009600 100036537 100039707 100040259 100041096 100041605 100041618 100042265 100042314 -20866836 49326392 -88583442 -14649687 106528912 -35656129 -35941871 -121758657 78137734 100042464 100042485 100216535 100217453 100312948 100312949 100312956 100312986 100312987 from which I deduce that the first 8 values could be four pairs. But that leaves 100042314 -20866836. What is the format for this list? Also, is there an easier way to go about this?
