I'm trying to overlay alignment tracks in the Gvis package. I have data for 3 technical replicates from 2 different cell types, so 6 alignment datasets in total.
I have managed to overlay the alignment tracks for the technical replicates in each cell type, so I have 2 composite alignment tracks in total, each with 3 overlaid alignment tracks; one from each technical replicate. However all tracks are currently in the default grey and I can't work out how to change the colour and transparency of the individual tracks so that when they are overlaid it is possible to discern the outline/colours of the individual tracks within the composite image.
Can anyone suggest how to do this. Is it possible in the Gvis package?
