¥ 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
