[Fmrlab_user] problem with running sample datasets

[Frank Haist]

Lin,
   I think this was the same problem I encountered in the sample datasets.
If you followed the instructions in the startup guide, you indicated that
there were 600 scans plus 10 dummies. This is in error. There are 500 scans
and 10 dummies. When JR pointed out this correction to me, everything ran
fine. Hope this helps.

---Frank
