I have 4 Gb, but I tried with a more poweful machine in the hospital and I got a similar error. I actually think there is a problem of alignment because the 3 T1s are quiet different from each other: they come from a patient affected by MS with a big lesion in the left frontal lobe. This lesion withdraws drastically in the last T1 as you can see from the two attachments. Moreover, I got a problem in the recon-all, given that freesurfer was not able to reconstruct properly the pial and white surfaces (the gray matter is spared in the patient, however it is not included in the lh.pial surf). Do you think there is a way to edit the brainmask for such a big lesion? Would this solve the problems with the recon-all base?
Thank you!

Hi - how much memory do you have on your machine?

I tried to run recon-all base for a longitudinal analysis on my data. But I get the following error:
