Thank's reply .I also found a problem that we can translate and rotate a molecule,and even we can apponit the molecule's internal origin and orientation ,but we can't apponit the molecule's orientation align some given direction as the align.py's function in the Graphene Nanoribbon Tutorial .
so I hope you can add the function that we can appoint the molecule's orientation through two aoms in the molecule. thanks
By the way , I also hope that we can apponit series electrode's voltage when we calculate current like computing the transmission spectrumm that we appoint the energy
