HEL– a program for model building based on a phased rotation, conformation and translation function
Frantisek Pavelcik · Journal of Applied Crystallography · 2006
HELis a program for creating continuous chains of polypeptides or polynucleotides from positioned fragments. Structure fragments are located by the programNUT, which performs a phased rotation, conformation and translation function. The output ofHELis a PDB file.
