Hello,

Option 7 can only set up a box whose cell vectors are parallel to Cartesian axes. To realize your aim, you should reorientate your system so that A-B is parallel to a Cartesian axis. You can easily finish the reorientation using subfunction 7 of main function 300, in which you can find an option "5 Make a bond parallel to a vector or Cartesian axis", after using it, export the new geometry, and redo single point calculation on it to obtain new wavefunction.

Question about function which generates grid

Dear Tian Lu, thank you for your convenient program for working with wave functions. Multiwfn has a function
5
1
7
that constructs a grid of points centered between two specified atoms. As far as I understand, this box is always oriented along the coordinate axes in the original coordinate system specified in the input file. I was wondering if Multiwfn has a function that will not only center the box between two specified atoms, but also orient it along the AB vector (where A and B are the specified atomic indices). If there isn't such a function, could you please tell me which source code file I should change to achieve my goal? Thank you, Tian Lu
