fafbseg.flywire.locs_to_supervoxels¶

fafbseg.flywire.locs_to_supervoxels(locs, mip=2, coordinates='pixel')[source]¶

Retrieve flywire supervoxel IDs at given location(s).

Use Eric Perlman’s service on spine.

Parameters

locs (list-like) – Array of x/y/z coordinates.
mip (int [2-8]) – Scale to query. Lower mip = more precise but slower; higher mip = faster but less precise (small supervoxels might not show at all).
coordinates ("pixel" | "nm") – Units in which your coordinates are in. “pixel” is assumed to be 4x4x40 (x/y/z) nanometers.

Returns

List of segmentation IDs in the same order as locs. Invalid locations will be returned with ID 0.

Return type

numpy.array

Examples

>>> from fafbseg import flywire
>>> # Fetch supervoxel at two locations
>>> locs = [[133131, 55615, 3289], [132802, 55661, 3289]]
>>> flywire.locs_to_supervoxels(locs)
