About the partner function

[Yxin3214]

Hello! I'm truly grateful for this extremely useful code that enables such amazing 3D displays. However, I have a few questions regarding the partner function. I'm attempting to retrieve the post - synaptic sites of neurons in the MANC (Flywire also when needed) database from a set of their presynaptic neurons, but it doesn't seem to be working. Could you please let me know what might be going wrong? I would greatly appreciate any help.
