HAAD is a computer algorithm for constructing hydrogen atoms from protein heavy-atom structures. The hydrgen is added by minimizing atomic overlap and encouraging hydrogen bonding. The excutable program can be downloaded at haad and the source code is downloadable at haad.f90 . More detail can be seen in README.

Cut and paste your structure in PDB format here:
