External Email - Use Caution

Hello,

I am a student using freesurfer 7.1.0 having some trouble with recon-all on some subjects. I am trying to calculate pial surfaces by adding FLAIR images to my T1 (already processed on recon-all beforehand), but encounter the following error:

Starting loop over 121584 vertices    vno = 0, t = 1.21632    vno = 20000, t = 3.38757    vno = 40000, t = 8.77043    vno = 60000, t = 11.8685    vno = 80000, t = 14.6273 error: Numerical result out of range error: MRIhistogramLabelRegion: constant image

Log is attached. Other subjects get stuck on the vno = 80000 step and run for days without progress. No artifacts in any of the images, but some have obvious structural variation such as enlarged and misshapen ventricles.

Thank you, any help would be greatly appreciated!

Sincerely, Pankush Kumar
