Dear FS experts,

When I run recon-all, one of my subjects get this error in mri_watershed process:

*************************WATERSHED************************** Sorting... first estimation of the COG coord: x=121 y=125 z=133 r=78 first estimation of the main basin volume: 2032411 voxels mri_watershed Error: Problem with WM_HALF_MIN too small

Can you tell me what's wrong? The input image seems to be good enough.

Thank you very much for your answers and for this excellent software
