Hi Francesca,
Sorry for the delay, you happen to post while I am traveling! This error message cannot be ignored. What -pad_to_node ld120 does, is create a dataset that has an entry for each of the nodes making up an icosahedron created with the -ld 120 option. Such an icosahedron defines a standard mesh for surfaces having 144'002 vertices. The surfaces onto which you are loading the dataset have less than 144'002 vertices for sure. I suspect you are using the original mesh surfaces or surfaces created with a lower mesh density. -- which spec file did you use when launching SUMA ?
You could replace ld120 with 0 and that should work fine (see help output for option -pad_to_node)

You'll need to repeat that step.

And that step
