[Chimera-users] the version of Ambertools that are used in the command "Write prmtop"?

[Victor Nazarychev]

Hello, Eric,

Sorry for the delay with response. But when I chose the Tools>Amder>Write
Prmtop> in the menu Select force field type I only can select 6 force
fields, and GAFF could not be chosen.

Could you please direct where in the Chimera menu I can select the option
to build a GAFF force field using the menu "Write Prmtop"?

Best regards,
Victor
