what was your original input volume? What dimensions/voxel sizes and how did you convert it to .mgz in the first place? On Fri, 22 Aug 2008, vin wrote:

hi,

i am new to freesurfer. I tried reconstruction three times, autorecon1 works fine, but autorecon2 gives same error.

*recon-all -autorecon1 -subjid your_subject_name % worked fine. :)

**recon-all -autorecon2 -subjid your_subject_name* % this gives following error came in 11/ 12 hours.

and that is how the directory looks like. [xx@xx mri]$ ls aseg.auto.mgz aseg.mgz brainmask.mgz norm.mgz nu_noneck.mgz orig.mgz T1.mgz talairach_with_skull.log aseg.auto_noCCseg.mgz brainmask.auto.mgz mri_nu_correct.mni.log nu.mgz orig rawavg.mgz talairach.log transforms

any one has any idea, where i am making mistake

Thank you very much / dhanyabad ji
