Dear FreeSurfer developers, 

I am trying to run longitudinal recon-all -long command. For some subject the recon-all -long command does not work and the error message indicate that 'transformed geometry does not match". I checked and the initial recon-all finished without error as well as the recon-all -base. I also tried to re-run de base but it does not help. 

Knowing that recon-all -long command worked for the majority of my subjects, what can explain that it does not work for some of them ? And how can we solve that problem ?

Thanks in advance for your help, 

Best, 

Yasmine
