Hi friends-of-SPM!
We are trying to coregister EPIs to a T1 anatomy in a patient with a
tumorous brain lesion. To avoid distortion by the lesion we decided to mask
most of it out. We then coregistered the altered EPIs to the T1 anatomy.
The next step hasn't worked so far: using the generated .mat-file to
reslice the original, unaltered EPIs to the T1, and do the statistics with
the resliced EPIs. I have renamed the .mat-file so it matches the EPI file
name, but I still get error messages. Does anybody know an answer? Does
anybody think this procedure makes no sense at all?
Another thought: to improve (?) coregistration we would like to tell SPM
that all zeros (after masking) are NaNs. I played around with matlab, but
couldn't convince it to save the altered data set...
I appreciate your comments!
