Well, DNA Strider, GCG, MacVector, and DNAStar all have components which
will predict the antigenic index of protein sequences...and this is
based on hydrophilicity, surface probability, and flexibility.  Also,
remember these algorithms are based on those proteins out there which
have actually been purified and crystallography studies performed on to
determine that they actually have these secondary structural elements.

If you use each of these predicitons (anitgenic index, hydrophilicity,
surface probability, and flexibility) to make your choice, then you
should have fair success.  However, from personal experience, it can
still be a crap shoot....

Hope that helps in any small way.....
