I can't find anything on this format - my ultimate goal is to display this in gbrowse.

Answer 1

[Istvan Albert]

I believe that the first column is the genomic coordinate, the second is the strand while the remaining 11 columns correspond to the tissues: Root, Seedling etc as shown on the browser in the track's legend.

If you transform each column into a GFF file you should be able to display it in GBrowse.
