Introduction

PyMOL Plugin for displaying polar contacts. Good hydrogen bonds (as determined by PyMOL) are shown in yellow. Electrostatic clashes (donor-donor or acceptor-acceptor) are shown in red. Close (<4.0 A) but not ideal contacts are shown in purple. Cutoffs are configurable. Exports the command `contacts` which takes two selections and an optional name for the generated contacts group. Alternatively, the selections can be chosen using a dialog box accessible from the Plugins menu.

  • sel1 = first selection
  • sel2 = second selection
