Morphology repair with NeuroR
There are presently three types of repair which are outlined below.
This is the process of curating a morphological file. It currently:
- removes zero-length segments
- raises if the morphology has no soma
- raises if the morphology has negative diameters
Note: more functionality may be added in the future
Cut plane repair
The cut plane repair aims at regrowing part of a morphologies that have been cut out when the cell has been experimentally sliced.
neuror cut-plane repair contains the collection of CLIs to perform this repair.
Additionally, there are CLIs for the cut plane detection and writing detected cut planes to JSON files:
- If the cut plane is aligned with one of the X, Y or Z axes, the cut plane detection can be done automatically with the CLIs:
neuror cut-plane file neuror cut-plane folder
- If the cut plane is not one the X, Y or Z axes, the detection has to be performed through the helper web application that can be launched with the following CLI:
neuror cut-plane hint
Unravelling is the action of “stretching” the cell that has been shrunk because of the dehydratation caused by the slicing.
The unravelling CLI sub-group is:
Unravelling is also part of the “full” process that performs unravelling and cut plane repair. The corresponding CLI is:
neuror cut-plane repair full
The unravelling algorithm can be described as follows:
- Segments are unravelled iteratively.
- Each segment direction is replaced by the averaged direction in a sliding window around this segment.
- The original segment length is preserved.
- The start position of the new segment is the end of the latest unravelled segment.
NeuroR is distributed as a Python package available on PyPi:
$ pip install --pre neuror[plotly]
Note: NeuroR relies on the experimental version 2 of NeuroM, hence the --pre option.
Only Python 3.6 and above are supported.
Prior to running pip install, we recommend updating pip in your virtual environment unless you have a compelling reason not to do it:
$ pip install --upgrade pip setuptools
