Hi Michael

Many thanks. Not really but maybe space and not knowing how to combining
them all easily and using a script to do this. Probably because most of the
data I used before was just AP so I was wondering whether really. I need to
do this. Also because of space and finding an automated way to combine all
data for all subjects.

Thanks

Aser
