Hi Sravanthi,

Can you check that "template_coreg.mgz" produced by samseg is aligned with your FLAIR image? There might be an issue with the initial template registration. If that is not the case, can you provide the full SAMSEG log? A warning might have been issued before it hung there.

Hi,

I am encountering an issue with Samseg while extracting lesion information from a CUBE FLAIR image. The process hangs for a long time and I have to forcekill the process after almost 2 hours. I did not have this issue with same subject T1w and T2 FLAIR images. Freesurfer - 7.2.0 Ubuntu 20.04

Read mesh collection: /usr/local/freesurfer/7.2.0/average/samseg/20Subjects_smoothing2_down2_smoothingForAffine2_lesion/atlas_level2.txt.gz Transforming points Transforming points Read mesh collection: /usr/local/freesurfer/7.2.0/average/samseg/20Subjects_smoothing2_down2_smoothingForAffine2_lesion/atlas_level2.txt.gz Read mesh collection: /usr/local/freesurfer/7.2.0/average/samseg/20Subjects_smoothing2_down2_smoothingForAffine2_lesion/atlas_level2.txt.gz

Could you help me troubleshoot this?

Thanks, Sravanthi.
