Hi Bruce,

many thanks! Actually, I wanted to try the examples first,  play around with it and than start to do the actual analysis.
By the way I discovered today that I use a rather old freesufer version (20030724) and I have to admit that I did not update to the latest version. So far I have prepared about 50 data sets. I wonder if I would have to do eveything once again after applying the update???   Do I have to update?

Best wishes and many thanks!

Lukas
