Bug identified in make_distance_histograms.py affecting all versions of QIIME

3 12 2011

Hi all,

We discovered a serious bug last night in the make_distance_histograms.py script. This bug results in incorrect t statistics and p values being generated under some circumstances. We’re still investigating this now, and we’re working on a fix.

This bug only affects the output from the make_distance_histograms.py script. If you’re using this script through the beta_diversity_through_plots.py workflow, these will be the files in the “<metric>_histograms” directory where <metric> refers to the beta diversity metric that you’re using. It does look like this bug affects all versions of QIIME.

We’re very sorry for any inconvenience this has caused. We take these issues very seriously, and we’d like to thank the QIIME Forum user “Poom” for bring this to our attention. We’re going to follow up in the QIIME Forum with additional details on this bug. Our plan for getting a fix to users is that we’re going to bump up the priority on the QIIME 1.4.0 release, which will incorporate this fix (as well as a lot of new features). Since we are already close to a release, we decided that this will be a more efficient solution than patching the 1.3.0 release. We’ll keep you posted with details on QIIME 1.4.0, but we expect that this will come out within the next two weeks.
