Contacts with symmetry related molecules in a crystal


This server calculates contacts between pairs of atoms. Pairs of atoms are analysed only if both atoms sit in different asymmetric units. The contact cutoff is 5.0 Ångstrom.


A contact is defined as two atoms for which the distance between the Van der Waals surfaces is less than 5.0 Ångstrom.
WHAT IF uses the following Van der Waals radii: C:1.8 Ångstrom; O:1.4 Ångstrom; N:1.7 Ångstrom; S:2.0 Ångstrom.
Warning, this server sometimes creates a looooot of output....
