It appears you are relying on grompp to figure out what parameters should be 
used for these angles, and apparently, given these atom types, there are no 
default values available in the force field you've chosen to use.  So either 
specify parameters manually or use a different force field.

If you need further advice, it would be useful to know the force field you're 
trying to use and see the problematic lines of the topology alongside the 
modified coordinate file.
