Hi Simon,
In 7.3.2, as you mentioned if you split recon-all into multi stages, '-careg' 
needs to be specified on the command line for autorecon2.
This has been fixed in dev version.
Best,
Yujing

Subject: [Freesurfer] Freesurfer v. 7.3.2 careg error


        External Email - Use Caution
Dear Freesurfer Support,
Under older versions of Freesurfer such as 7.2.0 I can split recon-all into two 
stages:
recon-all -autorecon1 -noskullstrip  -s sub -i sub.nii.gz
Manually create brainmask.mgz
recon-all -autorecon2 -autorecon3 -s sub
Using freesurfer v. 7.3.2 this fails. I looked at the log file and in the 
-autorecon2 stage the steps go straight from mri_ca_normalize to mri_ca_label  
missing out mri_ca_register so no transforms/talairach.m3z file is created.
I modified the second part to
recon-all -autorecon2 -autorecon3  -careg -s sub
and then it completed without error. Maybe this is intentional and there is 
another recommended way to do this multistage pipeline.
Thanks,
Simon
