Re: [Freesurfer] LGI ERROR

The FWHM used in the MC simulation is computed from the data itself. The final FWHM is a mixture of the applied FWHM and smoothness inherent in the data. LGI has a lot of inherent smoothness, so the final FWHM is very large. The MC sim table only goes up to 30mm, after that it generates an error

Hi professors,     I am using Freesurfer 6.0 for calculating LGI. I have done 'recon-all' for it. When I ran Monte Carlo in qdec (FWHM=10), it has errors: However, when FWHM=5, It was ok. What led to this result? I don't know why.

Thanks in advance ! Zheng
