Hello all,

I am unable to extract MAF files from a set of genomic intervals. I was previously able to do this (last week) but after the release of the new version I couldn't do this again. I have seen posts on biostars reporting similar problems, but none yet related to MAF tools.

The error I am getting is:

Traceback (most recent call last):

Thanks in advance!

We are testing, thanks for reporting the problem. This is at http://usegalaxy.org, correct?
