Mapping of hoc toploogy and 3D morphology

Post by shyam_u2 »

I recently exported a .asc file and created a hoc template. Everything works well, thanks to this forum and the well documented procedures on how to use import3D.
I am recording transmembrane currents from certain compartments/segments. I have the morphology plotted using the trees toolbox.
I need to create a map/figure which says that for example, currents recorded from 'nth' dendritic compartment corresponds to this dendrite (or point) in the 3D morphology plot. How do I map each compartment/segment in the hoc file to a particular point in the 3D morphology ?

Thanks in advance.

Major advice (not suggestion) before addressing your question: don't think in terms of compartment indices. Think in terms of range.

If you want to indicate a particular segment of a cell, create a Shape, attach an instance of any* point process class to the segment of interest, and then use the Shape class's point_mark method to indicate the location of the point process. *Consider using one that doesn't do anything to simulations, e.g. an APCount.
