Hi,

I’m analyzing data on our institution’s cluster and the fastest/easiest way to do this is w/o displays.  Unfortunately, while I am able to process data using SPM w/o displays, I am unable to preprocess.  Specifically, I receive an error during coregistration when I believe SPM is setting parameters related to a window it tried to open.  Error:

...nested function errors”

Is there any way to preprocess with SPM w/o displays?  Is there a version of SPM with all graphics-related calls disabled? I would try commenting that line out, but I’m almost sure there are numerous graphics-related calls throughout SPM  Any other recommendations?
