[BioC] Please Help with Starr Package

Hello To All,

The early processing and normalization functions within Starr all seem to be working quite nicely so I quite grateful  for this package, but I have stumbled in the graphing of the Affymetrix tiling array data.  

The vignette for the package has a nice example of plotting data in relation to all gene TSS's which I am trying to replicate.  To do this I need a GFF file that has genomic features such as "gene" or "TSS" , etc. (I am also interested in other features such as telomeres, centromeres so the transcriptAnno.gff in the example will be quite limited in utility.)



How do I create such a file? What files do I need?  Where can I obtain them? (goldenpath, SGD, etc.??)




I found the writeGFF function that uses a CEL and bpmap file to make a GFF but as far as I can tell that does not have genomic feature annotation information.

Thank you in advance for any help!!
