Handle long cell/section names

[Helveg]

Steps to reproduce:

• pip install dbbs-models
• Open a Python shell

> from dbbs_models import PurkinjeCell
# Basically uses Import3D to load an ASC morphology file
> pc = PurkinjeCell()
> from blenderneuron import neuronstart

• Open Blender, select the soma section in the cell group objects, press "Import Cell Groups to Blender"

When I try to create a minimally reproducible example I can in fact import the cell groups if I directly use Import3D.

Hi @Helveg,

Thanks for reporting the issue -- I was able to reproduce it.

The underlying cause is the limit on the length of blender object names. I will work on a long term fix, but I found a workaround that you could use in the meantime.

1. Create a dummy class that wraps one of the dbbs cell classes (this shortens the name of the cell in Blender), e.g.:

import dbbs_models
class PurkinjeCellDummy(dbbs_models.purkinje_cell_models.PurkinjeCell): pass

2. Instantiate the cell using the dummy class, e.g. pc = PurkinjeCellDummy()
3. Start BlenderNEURON in NEURON with from blenderneuron import neuronstart and import the group

I get this with the above steps:

Without looking closer at the morphology points, I'm not sure if those are an issue with BN or the morphology. I noticed that if the 'Interact with Sections' option is used, the lines dissapear.

Great news! Thanks for the workaround, I can continue playing around now!
