The data file specified by '-out' mimicks an fMRT raw data file.
It can be further processed using a standard sequence of statistical
analysis using 'vcolorglm' or 'vwhiteglm' to produce a statistical
map containing z-values for each ROI.
The parameter '-type' specifies the way in which the analysis is done. If
set to 'mean' the time courses within each ROI are averaged.
If set to 'pca', the first principal component within each ROI is computed.
Instead of specifying ROIs in a mask, it is also possible to supply a voxel
address. In this case, no averaging or PCA analysis is done. The program then
simply outputs the values of this single time course - optionally normalized to
N(0,1).
If a report file is specified (parameter '-report'), the output is printed
to this file in ASCII.
