[Dock-fans] Could Not Complete Growth Error

 Hi Austin,

This is definitely an orienting problem.  I would do as Joe suggests and visualizes your spheres, protein, grid, gird box etc. in chimera and verify that they are as you expect.   

See the following tutorial and the section on Surface and Spheres generation: 


I hope this helps,

Here is the dock.in file as run for benzoic acid. Also I tried running in verbose and got nothing of interest (see below). Also with this I am not getting any output files. Running in verbose created an output_ranked.mol2 file that contained no data.

Verbose output


  Number of heavy atoms = 9
  Number of rotatable bonds = 1
  Formal Charge = -1.00
  Molecular Weight = 121.12
  Heavy Atoms = 9
Orienting 7 anchor heavy atom centers

You might also try runing dock with the verbose flag.  This might help isolate where dock is encountering problems.  

See the following:

Hi Austin,

How are you orienting the ligands? I assume you are using automated_matching = yes? If so, what is your sphere input file that you specify in the parameter file? If you open up the spheres in Chimera, do they fall where you expect with respect to your protein? If you also open up the box / grid, does it surround the spheres with a wide margin? Feel free to cut and paste the contents of your dock.in file so we can see whether there are any red flags.

	I am new to Dock and am having trouble running through the tutorials with my protein of interest. Thanks for the patience and help in advance.

	Every time that I try and dock a ligand I keep getting the same error message of:

 ERROR:  Could not complete growth.
         Confirm that the grid box is large enough to contain the ligand,
         and try increasing max_orientations.

I have tried searching through the archives and so far none of the options that are listed have helped. I have tried to increase the size of the box manually to a 30x30x30 box, increase the max conformers, played with the bump filter, the internal energy and use of the flexible ligand. In addition I have tried to dock something small like benzoic acid and cyclohexene but keep getting the same error messages.

Very much appreciated
