Hi Lukas,
The new options -pad_to_node and -pad_label, now added to the program ROI2dataset, should do the trick.
To obtain full node listings, use -pad_node MAX_INDEX where MAX_INDEX is the index of the last node in your surface model ( = Number of nodes in the mesh - 1 ).
To find out the number of nodes forming the surface's mesh, open it in SUMA, then open the surface controller with 'ctrl+s'. There you'll find the number of nodes in the top left block. MAX_INDEX is that number - 1 .
linux_gcc32 binaries are ready by now, other binaries will be updated sometime soon.
cheers,
