If you have any groups that are free to rotate you will get frequencies that
are very small, or imaginary. You should only worry if these frequencies have
large magnitude. Using analytical calculation of the frequencies can also help
you to get a clearer picture if you are not doing that already.
If you want more detailed help please upload your output file somewhere
and send us a link to it.
Sincerely,
Ulf Ekstrom
