Dear John, dear All,
it was mentioned several times on the list that when doing the optimized
VBM-procedure, no brainmask should be used. While I understand that it
may not be advantagous since we are only dealing with brain-tissue
anyhow, I wondered if there are instances where it may actually be
harmful. Background is, if I want to compare data processed both ways, I
would like to keep as much of the steps identical. Also, I may want to
put at least some spatial restrictions on low-regularization
normalization.
Thanks in advance for yor input!
Marko
