LIPSIA     Concatenate design matrices
vcatdesign
The program 'vcatdesign' concatenates design matrices so that a fixed effects analysis between several sessions becomes possible. The inputs into 'vcatdesign' must have been generated by 'vgendesign' or 'vaddcovariates'. The concatenated design matrix can be used by 'vcolorglm' or 'vwhiteglm'.

Example:

vgendesign -in design1.txt -out design1.v -tr 2 -ntimesteps 648 -deriv 1

vgendesign -in design2.txt -out design2.v -tr 2 -ntimesteps 648 -deriv 1

vcatdesign -in design1.v design2.v -out design.v

This sequence of program calls first generates two design matrices from two text files containing design specifications of two sessions. These two design matrices are then concatenated by 'vcatdesign' to allow for a fixed effects analysis across sessions.

Parameters of 'vcatdesign ':
-help
Prints usage information.
-in
One or more input design files. Default: (none)
-out
Output design file. Default: (none)
