I'm trying to create an ideogram track in Gviz, but I receive the following error message that seems to have an issue with my chosen genome:


ideogram <- IdeogramTrack("chrIX", "sacCer3")

Warning message: In value[3L] : There doesn't seem to be any cytoband data available for genome 'sacCer3' at UCSC or the service is temporarily down. Trying to fetch the chromosome length data. '''

Is anybody familiar with this error, or a possible workaround?

Thank you,

This was just a warning not error, telling you that there is no cytoband data available for yeast genome ''sacCer3". However in that case, Gviz draws a simple chromosome highlighting the position of your interest:

plotTracks(ideogram, from=1e5, to=1.5e5)

Best Robert

Thanks for your response, Robert. You're right, I'm able to continue to plot a track, but I was hoping to include an ideogram that represented sacCer3. Perhaps there is simply no data available for sacCer3.

There is no cytoband data for sacCer3 at UCSC.

Ok. Thanks Robert. Ben
