If this is the last message before crashing, it sounds like it’s probably a memory issue – how much do you have available? CC’ing Stefano who might have an idea of the total memory requirement for lesions.

I tried to improve the system memory of my virtual machine but the same error appeared.

Any suggestions?

If the output directory is missing seg.mgz, then samseg failed. You’ll have to send us the log or some sort of information about the error for us to debug this.

Hello, I am trying to use SAMSEG to segment white matter lesions, I ran the following command:

run_samseg --input '/home/neuroimage/fsl/vascular/1002/U1002_3DT1.nii' '/home/neuroimage/fsl/vascular/1002/flair_reg.nii' --pallidum-separate --lesion --lesion-mask-pattern 0 1 --output '/home/neuroimage/fsl/vascular/1002/'

The output files were:

cost.txt
priors-testing.mgz
samseg.talairach.lta
template.lta
template_coregistered.mgz
template_transforms.mat

However I don't find any file with the white matter lesions segmented or a stat file. I would send you the terminal outputs but is too extensive. Would you help me?
