Many thanks for a quick response!

I installed the version 1.1.3 and tried rebuilding the database but got the following error:

cuff <- readCufflinks(rebuild=T)

> Hi Asta,
> I believe that I had already fixed this bug in the newer releases of cummeRbund.  Can you try to upgrade to the development cummeRbund version (1.1.3)?  You will have to rebuild your cuffData.db database with this new version.  Please let me know if this does not resolve your issue and I will try to work with you to get it resolved.
