getfMRInuisanceVariables: Extract generic fMRI nuisance variables for ASL or BOLD

In neuroconductor-devel/ANTsR: ANTs in R: Quantification Tools for Biomedical Images

Description

Will motion correct, run compcorr and estimate global signal. Outputs a list with the time series data matrix (time by voxels), motion and other nuisance variables, global signal (for BOLD or ASL), the mask and the average time series image. Meant to be used before filterfMRIforNetworkAnalysis or any other results-oriented processing.

Usage

getfMRInuisanceVariables(fmri, maskThresh = 500, moreaccurate = 1, mask = NULL)

Arguments

fmri	input antsImage or filename
maskThresh	will use this intensity threshold to estimate a mask otherwise will use the mask passed in
moreaccurate	zero, one or two with increasing accuracy/computation
mask	binary image masking the intput image, precedent over mask thresh

Value

outputs list described above.
