Hi Michael,
How many lines long are the files, and how many TRs are
you supposed to have per run? I guess this is one way of
asking whether you used the "-numout" option to waver...
If they are of the same length, then just concatenate them:
cat run1.1D run2.1D > run_both.1D
If they are not of the proper length, then either re-run waver
with -numout, or grab the correct number of lines:
head -120 run1.1D > run_both.1D
head -120 run2.1D >> run_both.1D
Note that the second command uses appending.
