Hi there,

I'm looking to calculate tSNR values and have used the following syntax, as per this post:

3dTstat -mean -prefix rm.signal.all all_runs.$subj+tlrc"[$ktrs]"
3dTstat -stdev -prefix rm.noise.all errts.${subj}_REML+tlrc"[$ktrs]"
3dcalc -a rm.signal.all+tlrc
-b rm.noise.all+tlrc
-c full_mask.$subj+tlrc
-expr 'c*a/b' -prefix TSNR.$subj

Now that I have TSNR.$subj files, I can visually inspect them for signal loss, but how can I extract the tSNR values of interest from these newly generated files?
