Unhelpful error messages

So, this is an old bug which I still need to fix, but since I have had a user report (again) that it is a problem, I thought a description of what the problem is would be helpful.

If you see:

"no Integrater implementations assigned for scaling"

This means you have not given xia2 any data for processing. The classic case is that you run xia2 in completely automatic mode and include the image name, viz:

xia2 -3d /data/graeme/s15a/xtal8/xtal8_1_001.img

Since the last argument should be a directory xia2 gets confused. This is simple to fix, I know, and will be for the next release.

Another perhaps more interesting cause of this is when the images are not readable - either they belong to someone else or someone has messed with the permissions. Again I need to check this, but it is harder...

So there you go, if you see this message check that you are giving a directory and that the images are readable.
