Failed to generate parameters
Parameter file was not saved.
WHAT I DID:
I have created a pdb file for Fe4S4: fes.pdb, and another for the 4
cysteines altogether cyf.pdb
in the latter I had to change the name of the SG,CB,CA,N,C,O to
SG1,CB1,CA1,N1,C1,O1
...
SG4,CB4,CA4,N4,C4,O4
Because all belong to the same residue and cannot have same name.
I have created a frcmod file for this.
when I use xleap:
loadoff fes.lib
loadoff cyf.lib
loadamberparams fe4s4cyf.frcmod
2FRV=loadpdb 2FRV-cut.pdb
xleap says: total atoms in file:32
the file contained 24 atoms not in residue templates (I guess thesse
are the SG1....O4 atoms)
bond 2FRV.1.FE1 2FRV 2.SG1
...
bond 2FRV.1.FE4 2FRV 2.SG4
check CYF
Unit is OK
check FES
unit is OK
check 2FRV

Can any one help me with this?
Thanks in advance
