Re: [Freesurfer] T1map processing error

2024-01-18 Thread Douglas N. Greve
The way I have done this was do compute T1w images (MPRAGE) through 
simulations, then run recon-all on that.

Dear FS community,


Recently our lab started collecting 3D-QALAS (Cho et al., 2023). Using 
this method, a quantitative T1map was constructed.



Trying to process this map, FS (v7.1.0) recon-all would output the 
following error:


mri_cc: no WM voxels found with norm > 40 -- check skull stripping


I would like to ask if anyone here has experience in processing 
quantitative T1maps with FS? Did you also run into that error? Were 
you able to solve it?



I am looking forward to hearing from you.
