Brian,

You decide on the name. It is a new subject composed of data from tp1id and tp2id. Once that 'base' subject is created, then you run your longitudinal analysis against that base:

recon-all -long tp1id baseid -all recon-all -long tp2id baseid -all

then compare tp1id.long.baseid to tp2id.long.baseid.

I am trying to run a longitudinal stream and I have already run all the scans through recon all already. I am on the second step

2. "-base" create the base template and process it cross sectionally:

recon-all -base <baseid> -tp <tp1id> -tp <tp2id> ... -all

Where do I find the baseid to put in the <baseid> spot?

Thanks in advance for any help with this.
