Hi there,

I tested out my preprocessing and first-level analysis using one machine (Mac iMac, El Capitan, conn 16a, spm12, and art-2015-10) and it ran smoothly, albeit it took a long time.

So I'm trying to navigate my analysis to a faster windows machine (Dell Precision T1700, Windows 7, conn 16a, spm12, and art-2015-10).  However, for some reason the same preprocessing pipeline shuts down during the first stage (realignment and normalization) on this CPU.

Any recommendations on how to resolve this issue would be very much appreciated!
