Hi Greve,

Thanks for your help. It is that I only use FWMH = 5 to do my study, it is decided by my data. Can I think it so?

Sincerely,

Zheng

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
