Hi all,
I am having a nucleic acid (RNA) + ligand (theophylline) + three
Magensium atoms + waters + sodium atoms in xleap. When I check the unit,
everything is ok, no errors and such (not even a warning). However, when
I want to save the amber parameters, leap tells me that it cannot find
the types for the three Magnesium atoms.
Am I missing something here?
I am using amber7.
Here is the output:
> check complex
Checking 'complex'....
Checking parameters for unit 'complex'.
Checking for bond parameters.
Checking for angle parameters.
Unit is OK.
> saveamberparm complex prmtop inpcrd
Checking Unit.
Building topology.
Building atom parameters.
For atom: .R<RG 1>.A<Mg38 38> Could not find type: Mg
For atom: .R<RG 1>.A<Mg47 47> Could not find type: Mg
For atom: .R<RG 1>.A<Mg52 52> Could not find type: Mg
Parameter file was not saved.
Thanks for any helpful comments.
Carsten
