Returns the grid cell coordinates, inluding the top limit.

Return type

numpy.ndarray

min :float#

The bottom limit of the grid domain size.

max :float#

The top limit of the grid domain size.

step :float#

The size of the grid cells.

use_2d :bool = True#

If a grid has a third dimension or is 2D.

grid_values :numpy.ndarray#

The coordinates of the grid cells.

idx_values :numpy.ndarray#

The indices of the grid cells.

grid :numpy.ndarray#

The grid, with the objects stored inside each cell.

class neurorosettes.grid.CellDensityCheck[source]#

Bases: abc.ABC

Class to evaluate the density of a tissue around a neuron object.

Multiple types of checks may be defined, such as grid-based or radius-based evaluations.

abstract check_max_density(cell, grid)[source]#

Returns a true boolean value if the density around a neuron surpasses the limit.

Parameters
Return type

bool

class neurorosettes.grid.OneLevelDensityCheck(max_neighbors=15)[source]#

Bases: CellDensityCheck

Class for a cell density check based on the neighboring grid cells.

Parameters

max_neighbors (int) – The maximum numbers of neighbors inside the cell grid and its neighbors.

check_max_density(cell, grid)[source]#

Checks if the number of neighbors is higher than the maximum limit.

Parameters
Return type

bool

class neurorosettes.grid.TwoLevelsDensityCheck(max_outer_neighbors=15, max_inner_neighbors=6, radius=18.0)[source]#

Bases: CellDensityCheck

Class for a cell density check based on a radius of interest.

Starts by checking if the number of neighbors is larger than the maximum, as done in the OneLevelDensityCheck. If this value is surpassed, the neighbors inside a radius of interest are selected and quantified. It then checks if there are more neighbors inside this radius than the expected value.

Parameters

  • max_outer_neighbors (int) – The maximum numbers of neighbors inside the cell grid and its neighbors.

  • max_inner_neighbors (int) – The maximum number of neighbors inside of the radius of interest.

  • radius (float) – The radius of interest.

check_max_density(cell, grid)[source]#

Checks if the number of neighbors is higher than the maximum limit.

Parameters
Return type

bool
