Currently working on a "proper" way to correct the chi-squared values (and hence the sd's) of intensities from Scala - first pass seems that it is much more effective and much quicker than the current run-scala-lots-remerging solution...

New Support Email

So, there are issues with emailing me direct at work - mostly to do with attachments. Thus I have set up a google mail account for providing xia2 support, which gives me around 2GB of storage.

Email xia2.support at googlemail.com - of course the xia2bb is still there as well.
