Positional Arguments

datafile

The name of the 3 or 4 dimensional nifti file to fit

outputroot

The root name for the output nifti files

Named Arguments

--dmask

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

--ncomp

The number of PCA/ICA components to return (default is to estimate the number).

Default: -1.0

--smooth

Spatially smooth the input data with a SIGMA mm kernel.

Default: 0.0

--type

Possible choices: pca, sparse, ica

Type of decomposition to perform. Default is pca.

Default: “pca”

--nodemean

Do not demean data prior to decomposition.

Default: True

--novarnorm

Do not variance normalize data prior to decomposition.

Default: True
