Dear Freesurfers,
After running the first tests of freesurfer 5.2, I found a file named $hemi.w-g.pct.stats on the stats folder. The last column of the file is a SNR calculation, i found on the help manual, that is required to add --snr to perform this calculation.
I'm interested to know how this SNR is calculated. Is there any method or paper related?
Thank you in advance,
/Jordi
Hi Jordi, the SNR in this case is just the mean gray/white contrast over an ROI divided by its standard deviation. No papers on it. doug
