Hi,

I was running selxavg-sess, and met this error:

It all goes back to the undefined "xyzscale".

Does that mean the nifti fiel I am trying to load is wrong? This problem is quite annoying because it appearance is unpredicatable. Sometimes our analysis go through fine, sometimes it pops out, and I have no idea what is the difference from those successful runs.

Thanks,
