Hi,

I'm having some troubles with the IdeogramTrack.

When I made the IdeogramTrack it works, but when I tray to plot it using
plotTracks it says that I cannot plot it.

 But I made this plot this week -worked-, and suddenly in the day after it
doenst worked anymore. And still doens't.

Can someone help me? Did anyone here had this problem before?


Thanks in advance,
Deisy
