Yes, but all the problems of limited time points still apply -- if you have only 70 good time points, and bandpass out a large frequency range, you may have very few effective data points left. There is no solution (that I know of) for that kind of problem.

3dTproject does allow for censoring as it bandpasses, unlike the other programs. Read the output of 3dTproject -help for details.
