Hi Adriana,

I don't seem to see your previous message posted. Can you share the images again, and recon-all.log too?

Best,

Yujing

Hello,

I'm just checking to see if you have received the images and if you are still working on my issue? I don't think I got any more replies from you and just want to make sure if you're still working on it.

Best,

Adriana

Hello,

Yes, of course. I trust you won't share the images, please.

Best,

Adriana

Hi Adriana,

Is it possible for you to share the T1 and T2 images so we can debug it?

Best,

Yujing

External Email - Use Caution Hi FreeSurfer Developers,

I'm trying to obtain brain parcellations/segmentations of a subject's brain, using T1 and T2 images, but when I execute the recon-all command, I get the following error message:

error: Numerical argument out of domain error: MRIhistogramLabelRegion: constant image error: Numerical argument out of domain error: MRIhistogramLabelRegion: constant image Segmentation fault Linux sharky 5.10.0-20-amd64 #1 SMP Debian 5.10.158-2 (2022-12-13) x86_64 GNU/Linux

recon-all -s Test_withT2 exited with ERRORS at Tue Jan 10 13:17:00 CET 2023

The FreeSurfer version I'm currently using is the freesurfer-linux-ubuntu18_x86_64-7.3.2-20220804-6354275, but I have also tried the exact same process (same command and same data) in the freesurfer-linux-ubuntu18_x86_64-7.3.0-20220718-7725d89 version and got the exact same error message. When I tried running the recon-all again with the freesurfer-linux-ubuntu18_x86_64-7.2.0-20210721-aa8f76b version, no error was reported and the recon-all outputs were correct. Recon-all works for versions reesurfer-linux-ubuntu18_x86_64-7.3.2-20220804-6354275 and freesurfer-linux-ubuntu18_x86_64-7.3.0-20220718-7725d89 if I use only the T1 image. The recon-all logs for the 2 failed and the 1 successful attempts are attached here. Can you help me figure out what the issue is? Why can't I run the recon-all using both T1 and T2 in the latest versions?

Best, Adriana Jorge
