Dear all,
        We are going to build = a protein model for MD simulation. But several loop regions (about 50 = residues in each missed loop) are missed in the crystal structure. Cou= ld someone know how to build these regions properly? Is there any pack= age or webserver that can do the job?
 
Many thanks.

A Single doub.

I would like to know if there are cc-pVDZ auxilirary basis set for RI-MP2 calculations for the Sc-Zn elements.

I am doing that in standard way: optimizing ground state structure>calculate vertical excitation for absorption properties and then optimize 1st excited state>calculate vertical excitation for emission properties. I am doing that DFT BP or BLYP functional. The infamous problem with this approach is that excited state optimization more often than not runs into crossing of the PES and TDDFT and CI just break down and ca not be used. While this is an infamous problem, I do not know of any way to solve it. How to work with these systems with crossing PES for molecules that are large, e.g. 50 atoms and more (hydrocarbons for now, no metal ions). I have not tried any multireference methods as I do not have experience with them, but (a) would they be able to perform adequately with 70-80 atoms and (b) do they normally have gradients implemented for excited state geometry optimization any insight or literature references would be appreciated Jonas
