Hi Rick and Priya-
I seem to be experiencing the same thing. I have nothing in my AP script about reml stuff, and even have "-regress_run_clustsim no" added to speed things up. My resulting proc.* script also has nothing in it about REML at all, and yet in the output it looks like 3dREMLfit is being run after 3dD because the "voxel loop" part takes upwards of 10 minutes to cycle through its counting. This is annoying when i'm trying to do rapid turn-around of mutiple AP runs and, like Priya, just want a simple linear regression for the time being. Am I missing something? let me know if i should send any code or outputs, thanks!
