7.1.494. stimband

Link to classic view

Usage: stimband [options] matrixfile ...

The purpose of this program is to give a frequency band that covers at least 90% of the ‘power’ (|FFT|^2) of the stimulus columns taken from one or more X.nocensor.xmat.1D files output by 3dDeconvolve. The band (2 frequencies in Hertz) are printed to stdout. This program is meant to be used in a script to decide on the passband for various pre- and post-processing steps in AFNI.

If the output band is ‘0 0’, this indicates that the input matrices did not have any valid columns marked as stimuli; this would be the case, for example, if the matrices had been generated solely for use in resting-state FMRI denoising.

Options:

-verb = print (to stderr) the power band for each
individual stimulus column from each matrix.
-matrix mmm = another way to read 1 or more matrix files.
-min_freq aa = set the minimum frequency output for the
band to ‘aa’ [default value = 0.01].
-min_bwidth bb = set the minimum bandwidth output (top frequency
minus bottom frequency) to ‘bb’ [default = 0.03].
-min_pow ff = set the minimum power fraction to ‘ff’% instead
of the default 90%; ff must be in the range 50..99 (inclusive).
