Re: [Freesurfer] Whole Surface SNR Calculation for Individual Functional Runs

There should be an fsnr.dat file in the fsfast analysis directory with the value that you want.

Hello Freesurfers,

  We are beginning to perform QC on our subjects and want to look at

signal to noise ratio. I've taken a look at the fsnr.nii overlay files, but we would like to be able to calculate a whole surface value for SNR for each functional run of each subject, so that we can exclude runs if that SNR values falls below our designated threshold. Is there a way to accomplish this?

Thanks,
