gmscalc

Description:

Inputs:

Outputs:

Usage:

Calculate the global mean signal, and filtered versions

usage: gmscalc [-h] [--dmask DATAMASK]
               [--normmethod {None,percent,variance,stddev,z,p2p,mad}]
               [--normfirst] [--smooth SIGMA] [--debug]
               datafile outputroot

Positional Arguments

datafile: The name of a 4 dimensional nifti files (3 spatial dimensions and a subject dimension).
outputroot: The root name for the output nifti files.

Named Arguments

--dmask

Use DATAMASK to specify which voxels in the data to use.

--normfirst

Normalize before filtering, rather than after.

Default: False

--smooth

Spatially smooth the input data with a SIGMA mm kernel prior to calculation.

Default: 0.0

--debug

Print out additional debugging information.

Default: False

Normalization options

--normmethod

Possible choices: None, percent, variance, stddev, z, p2p, mad

Demean and normalize timecourses using one of the following methods: “None” - demean only; “percent” - divide by mean; “variance” - divide by variance; “stddev” or “z” - divide by standard deviation; “p2p” - divide by range; “mad” - divide by median absolute deviation. Default is “None”.

Default: “None”
