WAP: water analysis package - a Web-based package to calculate geometrical parameters between water oxygen and protein atoms

Interactive Web-based software, Water Analysis Package (WAP), has been developed to calculate the distances between water oxygen atoms and protein atoms. The package incorporates all the three-dimensional crystal structures available in the Protein Data Bank (the atomic coordinates being updated regularly from the RCSB-PDB server), as well as offering the option to upload the atomic coordinates (PDB format) of new structures from the client system.
