[Simnibs-discuss] SimNIBS 4.0 beta1 charm command error: svg did not converge

[Mo Chen]

Hi there,

When we tried to use the *charm* command with SimNIBS 4, it gave an error
and suggested to use the *--forceqform* option. We then used the following
charm command:


*charm subj T1.nii.gz T2.nii.gz --forceqform*
It kept giving an error of "*numpy.linalg.LinAlgError: SVD did not converge*
"

Below are the details:

Version: SimNIBS 4.0 beta 1 for linxu
OS: Ubuntu 20.04.4 LTS
Command: charm subj T1.nii.gz T2.nii.gz --forceqform

Error message:
...

Any clue?
