Hi,

I am trying to plot some data in R using the Gviz package, but I can't seem to get the gene names to appear on the track nor can I get the ideogram function to work.

For the ideogram, I am aware that the yeast genome does not have cytobands, but I would like to plot the chromosome diagram and red bar mark indicating the region in my plots.

The error I receive when I try running IdeogramTrack is:

itrack <- IdeogramTrack(genome = gen, chromosome = chr)
Error in .local(.Object, ...) : Failed to obtain 'hguid' cookie

For gene names, I would like to have them on top of the yellow bars indicating UCSC gene locations, but I'm not sure how to do so.
