Yes, except -1Dright was renamed to -1Dleft when I realized (thanks to Gang Chen) that what I called the 'right' eigenvectors were usually called the 'left' eigenvectors. Oopsie.
The latest versions of 3dDeconvolve now do more collinearity checks, to see if the baseline model by itself has problems, etc. These features are to help narrow down the source of collinearity problems.
