Hello. I am attempting to include a 3drotate command in a script that will apply previously determined rotations and nudgings to new datasets, using this command:

3drotate -prefix test-rotate -ashift 0 2L 0 -rotate 0 0 0 -noclip test-reg+orig

For cases when there are no rotations to apply, I get the following error message, and the command does not run:

*** Why are all the angles after -rotate equal to 0?

I would like to be able to include cases that need shifts but no rotations in the script. Is there another program or option that can accomodate cases that require rotation and/OR shifting (nudging)?

Thank you,
Susan
