Steve, thanks a lot!
I never thought the problem is in avwmerge. The Analyze data were converted
from another format through a idl program i wrote. I had the output
filenames zero padded when i did the human subject data, but ignored when i
did the simulated data.

yes, the EV file we provided is an unweighted one to see the mean effect. In
experiment we applied 5 forces of different level on the subject in one run,
and each force applied only once. We are more interested in seeing the
linear effect from using 5 EVs in the setup.
Thanks again for spending time working on it!
