WHAT IF: a molecular modeling and drug design program
G Vriend - Journal of molecular graphics, 1990 - Elsevier
A FORTRAN 77 computer program has been written to aid with macromolecular modeling
and drug design. Called WHAT IF, it provides an intelligent and flexible environment for
displaying, manipulating, and analyzing small molecules, proteins, nucleic acids, and their
interactions. A relational protein structure database is incorporated to be queried. The
program is suitable for most common crystallographic work. The menu-driven operation of
WHAT IF, combined with the use of default values wherever user input is required, makes it …
