The function extracts data stored as raw within an object of class 'fmridata'.
extractData(z, what = "data", maskOnly = FALSE)
expandfMRI(z)
condensefMRI(z, mask)In case of function extractData an array of dimension data$dim containing either the
fmri-data or residuals. The other two functions return an object of class 'fmridata'.

The function extractData extracts data stored as raw within an object of class
'fmridata'. Functions expandfMRI and condensefMRI change the way
data and residuals are stored between full 3D data and data within a brain mask.
condensefMRI can also be used to set a more restrictive brain mask.
