[gmx-users] Chloroform simulation-Fatal error: Invalid angle type 1000

[Lakshman Ji Verma]

Hi everyone,

I am trying to simulate an organic molecule with chloroform as a solvent. I
prepared opls based topology for both the molecules from Ligpargen server.
The topology for chloroform works fine when I have only chloroform in the
system. I checked it against work done previously. However, when I add the
organic molecule in the system, it gives a *fatal error: Invalid angle type
1000.*

I am sure that the topology for the organic molecule is correct because I
have used it with water and ethanol earlier.
I found several similar threads but none was helpful for my case.

I checked several times. There are no spelling errors.
I have also tried changing the columns of the atom numbers in angles
section.

I am wondering if someone encountered such problem and can help me with
this. I would be very grateful.

I have attached the topology files.

Thanks
Lakshman
