Hello,

I am having problems preprocessing one subject. I acquire 6 functional runs and then collect the structural image at the end. This participant needed to come out of the scanner between runs 4 and 5. After putting him back in, it seems that we placed him in the coil slightly differently, because runs 1-4 do not quite line up with runs 5 and 6. Furthermore, the angle of the bounding box was different for runs 5 and 6 (which is why I'm guessing the dimensions don't match below). Consequently, when I run the Proc.py script, I receive the following error during 3dvolreg:

** Input ./pb01.s925.r05.tshift+orig.HEAD and base ./pb01.s925.r01.tshift+orig.HEAD don't have same dimensions!
Input: nx=126 ny=126 nz=83
Base: nx=126 ny=121 nz=75
** FATAL ERROR: perhaps you could make your datasets match?

I tried using the rotparent and gridparent options, but I think part of the problem is that I have only one structural scan. Currently I have aligned the data to the first run, which is why I am having problems with runs 5-6. How can I resolve this issue? Thanks for the help!
