Dear All,
I met a error when using fnirt with a lesion mask (setting in "--inmask"), but fnirt works fine without this lesion mask. This lesion mask is a binarised mask, has the same dimensions and qform & sform as correspondent T1, and works fine with flirt.
The error message is:
Error occured during estimation at first level of subsampling
Exception thrown with message: SpMat::DiagPrecond: Cannot condition singular matrix.
Any suggestions would be appreciated!
Best wishes,
Ling
