[AMBER] atom does not have a type

Hello,

 

I'm try to load my pdb file in to amber using xleap command:

 

>memS1 = loadPdb DOPC_128_lipid12cp.pdb

 

however, it seems something is going wrong, because it keeps showing:

 

>Warning: name change in pdb file residue 1;

> this residue is split into OL and PC.

>Warning: name change in pdb file residue 1;

> this residue is split into PC and OL.

>Warning: name change in pdb file residue 2;

> this residue is split into OL and PC.

>Warning: name change in pdb file residue 2;

> this residue is split into PC and OL.

....

(and it keeps showing all the 286 residue is split to OL and PC, PC and OL.)

>Created a new atom named: HT1 within residue: .R<NASN 1>

>Created a new atom named: HT2 within residue: .R<NASN 1>

...

(and it keeps showing all the 22 amino acid name has been created.)

 

If I ignore these warnings and keep going to generate *.prmtop and *.inpcrd file, it just doesn't work, with warning me (for example):

 

> Faltal: Atom .R<NASN 1>. does not have a type.

 

I have tried to uss addPdbAtomMap to map the changing names, it's still useless. So could you please tell me how to solve these problems?

Thanks a lot!

 

Sincerely yours,

Helen
