    Thank you, everything worked perfectly now!

    Thank you very much!!
    It worked now, and it found the paths! When I generate the plot for the laplacian of rho however i just get a straight line:

    I have sent you an email, thank you!

    Oxygen and tin. The BCP is only connected with a path (281) to oxygen, but for some reason not to tin.
    The level of theory for this was BP86-D3BJ/def2-tzvpp.

    Please find attached a screenshot of the bond in question. I have loaded it at a different lvl of theory to see if anything is different. But as you can see, the BCP is present, but only one path, instead of both.

    Additionally, in the table of all BCPs the BCP in question is stated as a (3,-1) without any atoms attached to it (in this case BCP333):

    I understand. I do not understand however, why not both paths are generated? The BCP is a (3,-1) and my frontier MOs and NBO analysis suggest there is a bond between the atoms in question (albeit polarized).

    Thank you for the fast reply!
    Unfortunately, I have tried that already and when i input the BCP in question it gives me the following:

    Which I thought made sense, because it is unable to connect the BCP to both atoms in the initial topology analysis, and only connects it to one of the atoms.

    I was trying to generate a 1D plot of laplacian of rho along the bond paths stemming from a BCP, however i always only get a path to one of the atoms, the path to the other atom is never found, can i change the threshold somewhere, or do you think something might be wrong with my input file? I used molden input generated from orca_2mkl.
