Dear Amber
I am trying to find to parameters for co-factor NADP+ by antechamber
But when I use this command:-
antechamber -i NADP_noH.mol2 -fi mol2 -o NADP_amber.mol2 -fo mol2 -c bcc
-pf yes -nc -3 -at gaff2 -j 4

It gives me this error

Welcome to antechamber: molecular input file processor.

acdoctor mode is on: check and diagnosis problems in the input file.

But, you may safely ignore the warnings if your molecule
         uses atom names or element names as atom types.

Weird atomic valence (3) for atom (ID: 55, Name: C4N).
       Possible open valence.

Hoe to solve this issue
I have attached .mol2 file if there is something wrong please tell me.

thank you in advance
