Hi there,
I just want to create solvent boxes, first I tried with methanol.
I tried this but didn't work:
(tleap)
loadamberparams frcmod.meoh
loadamberprep meoh.in
loadOff meohbox.off
solvateBox MOH MOH 11
savepdb MOH moh.pdb
saveamberparm MOH moh.prm moh.crd
Errors:
...
Error: For atom (.R<MOH 243>.A<HC3 4>) could not find vdW (or other)
parameters for type (H1)
Warning: Parameter file was not saved.
But I manage to build a box this way:
(tleap)
loadamberprep meoh.in
savemol2 MOH moh.mol2 1
Then edit moh.mol2 so I changed atom types to lowercase and changed CT to
c3. Then I did:
(tleap)
source leaprc.gaff2
mol = loadmol2 moh1.mol2
solvatebox mol mol 11
saveamberparm mol moh.prm moh.crd
savepdb mol moh.pdb
and this worked, I could even run a simulation with gmx after converting
amber input files with ACPYPE.
What am I missing?
Many thanks in advance,
