Hi,

I'm trying to map the functional data to surface using 3dVol2Surf and then extract the data within surface ROI. Then I met ** FATAL ERROR: Input and mask datasets are not same dimensions!

I checked their number of nodes and found there's a lack of nodes for the functional data. It's weird because this doesn't happen to another run of this subject (scanned just 2 min before the problematic run). Any suggestions to solve this problem?

I also found the number of nodes of functional data varied if I made some changes to the options of @SUMA_AlignToExperiment which may affect the input for -sv of 3dVol2Surf. So something wrong with the alignment?

Thanks in advance!
