LigandFit (distorted manesium hexahydrate cluster)
Dear All, I am trying to run " LigandFit " with the following hydrated magnesium hexahydrate cluster (without the hydrogens) pdb.

Hi Hasan, I can help with part of this...yes, you can run without any connectivity...if you turn off real-space refinement: refine_ligand=False I took your mg hexahydrate and ran it that way and it ran through ligandfit just fine. All the best, Tom T the addition of hydrogens.

Is it a bug or am I making something wrong? Does the search pdb HAVE TO be covalently linked? or can I search for a cluster?
Thanks.
