Hi,
In this case at least the non-bonded parameters seem to be the identical.
Are there some different parameters for atom types which only differ in case?
That is bad practice IMHO.
But if so, we should consider changing this or adding an option.

Subject: [gmx-users] [ atomtypes ] are not case sensitive?
Dears,
Playing with amb2gmx.pl, I have in my topol.top file something like:
[snip] C C 0.00000 0.00000 A 3.39967e-01 3.59824e-01
; 1.91 0.0860
... c c 0.00000 0.00000 A 3.39967e-01 3.59824e-01 ;
1.91 0.0860[snip]
Then, running grompp, I got several warnings, e.g.:
WARNING 1 [file "multi_GMX.top", line 38]:
Overriding atomtype c...
Is there any special reason why atomtypes are not case sensitive? Fortunately
it seems that all lower case atomtypes from gaff.dat (GAFF) mirrors the upper
case of, say, parm99.dat (AMBER 99). But this is not good in MHO.
Many thanks in advance.
Cheers,Alan--
