No, its not related to parameterization methodology. it is a different
question...
how can i identify the molecule as methylamine (for example) since in the
.rtp the molecule type is written as [MAM1]
[ MAM1 ]
[ atoms ]
N1 NG321 -0.990 0
C1 CG3AM2 -0.060 1
HN1 HGPAM2 0.390 2
HN2 HGPAM2 0.390 3
HC1 HGAAM2 0.090 4
HC2 HGAAM2 0.090 5
HC3 HGAAM2 0.090 6
[ bonds ]
N1 C1
N1 HN1
N1 HN2
C1 HC1
C1 HC2
C1 HC3
Is thr any hint such tht i can identify the molecule type written in .rtp
file.??
Or should i manually find it out..??... but in case of Glycine the molecule
type is [GLY] which is easy to find....
How can i solve this issue..??
You need to go to the original CHARMM force field files. These include names
and (typically) chemical structure drawings.
