Find the portion of code which shows you the error message and try to find the corresponding check. Use for example in the src directory:

 

grep 'lone pair only supported for water‘ *

 

This should point to the right source file.

Betreff: namd-l: Probelm with Lone Pairs on TIP4 model

 

Hi,

I want to run TIP4 water model , but when i change the mass of oxygen atom, NAMD notices this is not the water molecule, and throw an error saying 'lone pair only supported for water '.

 

I effect , i want to simulate H2S which is very similar to H2O and can be simulated via a force field similar to TIP4.

But from the mass of sulfur atom , NAMD distingush between H2S and H2O , so give the above-mentioned error.

 

In the source code, how can change the defult mass for oxygen atom?
