Trying to plot the Gallus gallus karyotype using data from the library(BSgenome.Ggallus.UCSC.galGal6) I get an error message:

> kp <- plotKaryotype(genome="galGal6")
[1] "galGal6"
Loading ideogram...
Error in normArgTrack(track, trackids) : Unknown track: cytoBand
cytoBand informatin is not available, only get ranges.
Loading ranges...
Done
**Error in `[[<-`(`*tmp*`, name, value = character(0)) : 
  0 elements in value to replace 464 elements**

It´s probably my mistake. I do not have experience working with R. Thanks in advance.
