Hi Ignacio,
I am glad to hear that your problem has been solved
.
The reason: what you copied from .pdf file has hidden characters in it. On my MacBook Air running OS X 10.7.4 (Lion), I have the following:
more side_view.dat
by rotation y <96>30
by rotation x 20
Notice the extra characters <96>? Program
vi shows the same info, while
emacs displays \226. I do not know what the chars mean exactly, but '
rotate_mol' certainly do not like them, and outputs sensible error message:
wrong <by rotation> format
Thanks for using 3DNA. Keeping asking if anything is unclear or needs to be improved -- it's an ever-learning experience for all of us; through the process, we make 3DNA a better tool to serve the community.
