SNR Calculation Looks Inverted #238

Open milham01 opened 11 years ago

milham01 commented 11 years ago

The SNR is in decimal form; this does not seem to be temporal mean/temporal std.

Please check this calculation and correct.

check the math for TSNR calculation

sgiavasis commented 8 years ago

CPAC calculates SNR using 3dcalc- it divides the mean of the functional by the standard deviation of the functional. These are done using a mean functional image and a standard deviation map both in each participant's anatomical space.

@ccraddock , is there a specific TSNR calculation we should refer to?
