Hello,
for VBM-like processed DTI-data, could the SnPM toolbox be used for
non-parametric analysis?
(as non-Gaussian distribution of residuals tends to be present in the data
even after smoothing)?
If yes, what would be the settiings for
(a) a two-group comparison and
(b) for a simple correlation over the scans of one group using one , ideally
two covariates (one cov. of interest, one nuisance variable)?
Many thanks in advance,
Philipp
