I tried to run tracula using cvs registration options (registration to MNI works for me well), but the -prep script  crushed, when using cvs_avg35 option. I double checked the configuration file and it seems ok to me. After trying several times, I am still not able to figure out what the problem exactly is. 

The trac-all.log file is attached.

I will be very thankful for any advice or help.

Best
