Hello all,

I'm new to this and I'm having problems running probtrackx2 with more than one target.

Everything works fine when I have just one seed and one target, but when I try it with two target regions (for classification), I get the following error and the files seed_to_target are not created.

Do you know what might be the reason for this?
