In preparation for running statistical analysis with the Randomise program, design matrix and design contrast files were created.  The participant directory was organized so that the first ten participants were the TBI patients, followed by the ten OI controls.  The design matrix was used to indicate the group assignment of participants for the Randomise software.  Each of the twenty rows in the matrix represented a participant, with left and right columns representing TBI and OI conditions respectively.  A "1" was placed in the column to which the participant corresponded, with a "0" in the non-applicable column.
