LOOPP is a public domain package for protein recognition and design of folding potentials. Versions 1.0 and 2.0  were written when I was working with Ron Elber at the Cornell's Computer Science Dept. and Ron contributed in many ways into the development of these early versions. LOOPP 2.0 includes standard and novel sequence to structure (threading), sequence to sequence and structure to structure alignment algorithms and potentials. LOOPP can also be used to develop new folding potentials. To download the source code of LOOPP 2.0(00) follow the links included below or go to the LOOPP web page at the Cornell Theory Center.
