¥ 3dDeconvolve now
checks for duplicate -stim_file names and for duplicate
matrix columns, and prints warnings
H These
are not fatal errors
o If the same
regressor is given twice, each copy will only get half the
amplitude (the Òbeta weightÓ) in the solution
¥ All-zero regressors are now allowed
H Will get zero weight in the
solution
o A warning
message will be printed to the terminal
H Example: task where subject makes a
choice for each stimulus
o You want to
analyze correct and incorrect trials a separate cases
o What if a
subject makes no mistakes? HmmmÉ
