[gmx-users] Coordinate file for charmm36 POPC

[yashita thakur]

Thank you Justin for you help.

But I am asking about  Peter C. Lai POPC lipid which is for charmm36 force
field please see the link below

http://cesium.hyperfine.info/~peter/gromacs/popc36/

Not Peter Tieleman as mention in your tutorial as it is for united atom.

Can I use Peter C. Lai POPC lipid ???

Another question is if I want to reduce some lipid from Peter C. Lai lipid
Its 238 POPC but if I want only 200 then what is the command??

Please Help


Warm Regards
Yashita Thakur
