Hello,
I'm using SPM 99 for comparing populations
(1scan/subject)of ill subjects versus a normal
population in SPECT models and I have some problems
with normalisation because I want to calculate for
ill subjects the mean excluding very pathologic voxels
so
1) how can I change the value of 1/8 in global
calculation (proportionnal scaling) option mean voxel
value (fullmean/8) ?
2) what are the value required in global calculation
option user specified ?
Thanks,
Xavier Hatchondo.
