Problems with gray matter segmentation

Dear SCT Team:
When I was doing gray matter segmentation, the results I got were not ideal.The command I used is as follows:“sct_deepseg_gm -i t2s.nii.gz -qc ~/qc_singleSubj”.
And this is the Sample data: (9.4 MB)

Hi @jie_Liu,

The problem is caused by the image, which does not show the gray matter:

It is not possible for an algorithm to automatically segment something that is not visible in the image. The same goes for segmentation done by a human. I suggest updating the imaging parameters to improve the WM/GM contrast.


Okay, I understand, thank you very much for your reply.
