Hi Maxime, 

please keep previous conversation in the email (so that it is easier to check the original question). Also let’s keep this on the list. 

I do not understand what you mean with “there is not strict alignment”. If you open the norm.mgz from base, tp1.long.base and tp2.long.base they should all be perfectly aligned. If that is not the case something went wrong with your processing - maybe the way you called recon-all or maybe the editing/re-reunning process. 

I would recommend to 
- rename base and the 2 long directories
- re-run the base and inspect surface
- re-run both the long (with recon-all -long …) and inspect if everything is aligned. 

Best, Martin

Hi Martin,

Thank you for your answer, but (un)fortunatelly, I double checked, I didn't made these mistakes. 
The overlay of the surfaces (opened from each tp.long.base directories) is still wrong.
I noticed that there is not a strict alignment between the norm volume from base and the one from the tp1, whereas the alignment is correct between base and tp2..

Have you ever faced this situation ? And if so, is there anything else to try ?

Hope a made myself clear, if you need more captures/informations just ask me.

Best,

Maxime
