I have made box of 1 nm and then using command
"gmx solvate -cp 1AKI_newbox.gro -cs ethanolamine.gro -o 1AKI_solv.gro -p
As per my knowledge, i solvated my protein in ethanolamine.
Now I want to know the number of ethanolamine molecule present in box. Then
I looked in to *.top* file but no information is availble in the file (SOL).
(As per intruction, program is only hard-coded to update the topology in
the case of water).
I found increase in number of molecules from 7200 to 128004 in

respectively. It means something is inserted in box (must be
How can i know number of ethanolamine molecules?
for reference please find attched files.
Thanking you in advance.
