Hi Ziad,

I ran this command line:

ROI2dataset -prefix lh.V1dorsalDM.1D.dset -of 1D -input lh.V1dorsalDM.1D.roi

I was just trying to follow the procedure in the suma_demo I downloaded, in particular run_ROI2dataset and run_ROI2dump but I probably did not correctly understand some steps.
As you suggested, I tried to add the -padd_to_node option to ROI2dataset and it worked!

Now, I would like to extract the time series from a functional run that I mapped to the surface, masked by these surface-based regions. Which function do you suggest me to use for having a time series associated with each vertex (and coordinates)?

Thank you so much!

Best
Francesca
