Dear all,

 

I work with amber 11 and ambertools 1.5 (patched).

 

I am trying to use leaprc.amoeba in sleap.

Here is my input file :

 

source leaprc.amoeba

source leaprc.gaff

 

frcmod1 = loadamberparams 1.frcmod

 

prot = loadpdb protein.pdb

lig = loadmol2 ligand.mol2

 

complex = combine {prot lig}

saveamoebaparm complex complex.top complex.crd

 

quit

 

 

 

This works fine with leaprc.ff03.r1 or others. But using leaprc.amoeba,
I get the following message when sleap try "saveamoebaparm ...":

"get typeid of -1

Error (get_iptr): while retrieving parameter typeid, impossible abs ID
(-1)"

 

Is it because gaff and amoeba are not compatible?

PS : cannot have access to amber mailing list archives, so I could not
check if there is a solution already posted...
