Hello Pablo,
SVC in principle is applicable to any type of SPM/contrast, so, also fc
analyses. To define a ROI posthoc (i. e. after seeing a peaking effect),
however,
might me conceptually questionable. If the ROI is defined a priori, the
procedure seems less critical as you increase the weight
of "expected/hypothesized" findings compared to findings outside that area.
