3dcalc

AFNI Message Board

Hello AFNI experts,

I planned to use 3dcalc to calculate the standard deviation of a bunch of correlation maps. However, I have more maps than the alphabet, and I know in 3dcalc, you specify each data set you want incorporated in your 3dcalc expression with a, b, c. Are you restricted by the letter of the alphabet? Can you go beyond 26 variables?

Thanks,

Emily

Hi, Emily-

I think you will be happier using:


3dMean -stdev -prefix OUTPUT  [all dset names, e.g., with a wildcard expression]

Probably for most 3dcalc things that would require a large number of letters, there is a more specific program within AFNI.
