I guess this one is for Peter: Would it be possible to add a -weights option to 3dNetCorr so that one could compute a weighted average for each TR rather than a straight up arithmetic mean?
-weights would cause a 1D file to be read. It would have to be as long as there are TRs in -inset
Having looked over the code briefly, I think it would yield something like RAT[n] = (ts[n]*w[n])/Nv[0] at line 41 in rsfc.c where w[n] is the weight for TR n.
