Quick tour

Basic installation

First of all, you need to download the VMD plugin.
Decompress it and follow the instructions in the README file :

First steps with Pck

  1. load a molecule in VMD
  2. In the VMD menu, select the "pocket analysis" item
  3. Specify the vmd-molid of the vmd-molecule in which you want to detect pockets
  4. Launch computations

...A bit further

  1. You can use the selection field to restrict the pocket detection to a subset of atoms in your vmd-molecule. The selection query is sent to VMD, it can be any vmd selection query, for exemple : "all", "protein", "all and not water"...
  2. You can modify the probe radius (defaults at 1.4 Angstrom, the radius of a water molecule)
  3. You can change the detection algorithm to switch from closed pockets (default) to wide opened pockets.
