Hi Rick,
Thanks for the quick response!
I tried warping the anat to match the EPI which worked but, although much easier and quicker, it reduces the image resolution which is not desirable for the ROI approach that I am taking. So I added the -master option using the EPI dataset as a grid and this works if I use it after motion correction. However I noticed that a previous post stated that 3dAllineate with the -EPI option (which I am doing) should be run before motion correction. Yet, when I try to run 2dImReg and 3dvolreg on the aligned EPI data I receive the following error:
++ 2dImReg: AFNI version=AFNI_2007_05_29_1644 (Sep 28 2007) [64-bit]
Choleski factorization failure in startup_lsqfit

Is it ok to for me to run 3dAllienate with -EPI option after the data has been motion corrected? Or is there a way to solve the problem that I am having trying to run 2dImReg and 3dvolreg on the aligned EPI data?
Thanks,
Kristen
