Hello,

I am having difficulty with the makeGeneRegionTrack command in cummeRbund. Below is what happens, after rebuilding the cuffData.db with the gtf file downloaded from the cufflinks website. I've had no problems operating any other cummeRbund commands, so might data is presumably is sufficient and uploaded correctly.

I have previously posted on this problem (Cummerbund Gene Tracking), but the following is after incorporating the recommended genes.gtf file from the tuxedo website.

I'd appreciate any advice on what the problem might be.

Thanks, SH

The database appears to be successfully built. I then make and call my gene of interest:

4    NA   Insm2  NM_020287     Insm2  P1443     TSS20567

When I then try to make the gene region track, I get the following:

>     genetrack <- makeGeneRegionTrack(myGene)
Error in `[.data.frame`(features(object), , featCols) :

Hi Eric,

Did you ever manage to solve this issue?
