[BioC] readVcf bgzip error

Fri Oct 12 22:33:21 CEST 2012

Valerie,

Thanks for looking into this.  I'm new to Biocondoctor, but not R.  I hadn't realized update.package didn't update Bioconductor.  Anyways, this did indeed fix my problem.

Again, thanks.

Brian

Brian,

Thanks for sending the sample data. I've tested the file on Windows and am not able to reproduce the error. It looks like you've got some old packages in your installation. A new version of Bioconductor (2.11) was just released last week. To update your packages you can follow the instructions here,

http://bioconductor.org/install/

Let me know if you still get the error after updating.

Valerie
