I am very keen to use the grid.chromosome function in the bioc package quantsmooth. I'd like the karyograms to be rendered *without* cytobands -- so that the interior of each idiogram is available for me to plot other data into. I notice that there is a 'bands' argument to grid.chromosome, with expected value of either 'major' or 'minor'. Would it be possible to support a third option, 'none'? Thanks! - Paul --- sample code library (quantsmooth) grid.newpage () grid.chromosome (22, units="bases", height=0.15, width = 0.5, cex.leg=1.5, bands='major')
