v3.4.0

What's Changed

Two large changes to the SWC reader; this may impact reading, hence the increase in minor version number:

• Efficient swc build (#476)

  • handles locale correctly, so decimal numbers using comma are allowed
  • ~800 line SWC parse time goes from 0.976 to 0.699
  • Doesn't create changes to bifurcations at the root nodes of SWC files
  • More strict Neuromorpho 3 point soma checks disallow repeated Sample IDs
  • Follow https://swc-specification.readthedocs.io/en/latest/swc.html more closely
  • Allow only positive integer Sample IDs
  • Allow for the type of neurite to change at bifurcation points
  • Allow Window style End of Lines
  • allow trailing spaces on sample line

• Section change (#510)

  • A section within MorphIO is defined as a series of segments between
    bifurcation/multifurcation points. However, SWC files allow section
    change without a branch. Normal parsing of this will raise an
    exception, but can be allowed using the option UNIFURCATED_SECTION_CHANGE
  • Create a warning if the section type changes without a bifurcation
  • Add option to allow for sections changes in SWC files without bifurcation
