Exception: no child seg nor parent seg, with active channels, was found

Hi! I receive the topic error when do this:

from neuron import gui,h
import neuron_reduce

h.load_file('bAC_327962063.hoc')
complex_cell = h.bAC_327962063(0, '', '02583f52ff47b88961e4216e2972ee8c.swc')
neuron_reduce.subtree_reductor(complex_cell, [], [], reduction_frequency=0)

Traceback (most recent call last):
  File "/sonata_network_reduction/reduce.py", line 21, in <module>
    neuron_reduce.subtree_reductor(complex_cell, [], [], reduction_frequency=0)

    raise Exception("no child seg nor parent seg, with active channels, was found")
Exception: no child seg nor parent seg, with active channels, was found

Some details. There is no apic SectionList. create_reduced_cell creates 9 basals/sections: {, model[0].dend[0], model[0].dend[1], model[0].dend[2], model[0].dend[3], model[0].dend[4], model[0].dend[5], model[0].dend[6], model[0].dend[7], model[0].dend[8]}. Somehow the last of basals (model[0].dend[8]) is not in reduced_seg_to_original_seg that returns create_seg_to_seg, and because it is a section with a single segment in it => no parent/children to copy mechanisms from => error.

I've sent the files on your email.

Here is a fast fix:

But I need will need to test it further to validate that the synaptic mapping is working correctly

Thank you! It works. I can continue with my work.
