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

2011-01-03 Thread Adam Nitenson
Is that the only (relatively convenient) way to get this data? I'm not sure if we're ready to start reprocessing all of our subjects. I noticed that the selxavg-sess command had a "-svsnr" argument for "save estimate of SNR to analysis/estsnr". Would this give me the relevant data? My mai

Hi Doug, Is the fsnr.dat a Stable 5 feature? I'm working on Stable 4, and cannot find this file in my analysis directory, e.g. /cluster/roffman/users/folate_subjects/FB0011099AA/bold/fmcsm5_functionals ...or anywhere else in the subject directory. All I see are the fsnr.nii overlay files. -

There should be an fsnr.dat file in the fsfast analysis directory with the value that you want. doug On 12/20/10 1:30 PM, Adam Nitenson wrote: > 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

[Freesurfer] Whole Surface SNR Calculation for Individual Functional Runs

2010-12-20 Thread Adam Nitenson
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
