a error about antecamber about yank

[jslim-furame]

Total number of electrons: 241; net charge: 0
INFO: Number of electrons is odd: 241

The error occurs because the number of electrons is odd. Please check the charge of your ligand or the protonation states. Run the antechamber in your local computer and verify what is the problem. Consider adding hydrogens using Chimera or other well-known tools like Maestro. If the charge is wrong, specify "-nc" flag in your YANK yaml file.

Thank you for your response. I have checked the charge of the ligand with a positive charge, and added the netcharge = 1 in my YANK yaml file, but I got another error in the following:

I still need your help to solve this problem, many thanks.

Hi @kingljy0818. This looks like a simple YAML syntax error in your script. Some extra : character somewhere?

[jslim-furame]

Simply, bcc -nc 1 Its syntax follows antechamber. 2022년 9월 8일 (목) 21:02, kingljy0818 ***@***.***>님이 작성:

Thank you for your response. I have checked the charge of the ligand with a positive charge, would ask you how to specify the '-nc' flag in my YANK yaml file? — Reply to this email directly, view it on GitHub <#1289 (comment)>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/AKXZQ6SHMDMUSM3Q662D7W3V5HIVJANCNFSM6AAAAAAQHKKXBA> .
