Thank you very much for the reply!
I tried to follow the example but met some errors. From my understanding, when using 3dmaskave, the mask (ROI dataset) and input (resting fMRI dataset in my study) should have the same size. So, I checked the size of resting data and used it for -pad_to_node.

After running the command "ROI2dataset -label_dset surfROI_lv1.niml.dset -pad_to_node 135170 -overwrite -input surfROI_lv1.niml.roi" , I got

ROI2dataset: Adopting Parent_idcode_str (AFN_U28lct8gSjxH-44gCdqHGA) in ROI l_v1
++ Notice SUMA_ROIv2Grpdataset (SUMA_Surface_IO.c:6524 @20:09:54):

ROI contains node index > padding limit
No padding done.
-- Error ROI2dataset (SUMA_ROI2dataset.c:463):
Failed in SUMA_ROIv2Grpdataset

And when I tried the command on ROI of the other hemisphere, I got:
ROI2dataset -label_dset surfROI_rv1 -pad_to_node 135446 -overwrite -input surfROI_rv1.niml.roi
ROI2dataset: Adopting Parent_idcode_str (AFN_LOuSRAUTEdI-NTdTZv-G0g) in ROI r_v1

Is there something wrong with the node size I used?
I used SurfDsetInfo to check the information of resting dataset, the output is as follows:
