Dear SPM users:
1) I would like to compare volumes pre-processed in SPM5 and volumed
pre-processed in AFNI for a sanity check. Can this be done, and if so,
what would be the best method for accomplishing it.
2) I have an AFNI data set that I have converted into NIFTI format and
used these files to duplicate (in SPM5) the first and part of the second
level analysis as was done previously in AFNI, but these analyses do not
match up. I used the following to convert the AFNI pre-processed images
into NIFTI format:
3dafnitonifti -float snkrtfSub01_run1+tlrc.BRIK.gz
and then extracted the gzipped image before continuing on to the first
level analysis. Any suggestions on what may have gone wrong with the
conversion from BIRK to NIFTI or any pointers / tricks on how to handle
NIFTI images in SPM5.
Many thanks,
