NGSidekick

Tools for working with neuroglancer. See docs.

Feature Highlights

Segment properties: read and write neuroglancer's precomputed segment properties format from a pandas DataFrame.
Local annotations: construct local annotations directly in viewer state. (API subject to change.)
Precomputed annotations: export annotations in neuroglancer's precomputed annotations format from a pandas DataFrame.
- Supports all five annotation types:
  - point
  - line
  - axis_aligned_bounding_box
  - ellipsoid
  - polyline
- Per-annotation properties (numeric, enum/categorical, and rgb/rgba color).
- Per-annotation relationships (lists of related segment IDs, used by neuroglancer to filter annotations by segment).
- Written to all "index" types (annotation id, related segment, and multi-level spatial grid)
- Sharded output, written in parallel via tensorstore.
- Note: writing directly to cloud storage is not yet supported; outputs must be written to a local filesystem (you must upload to cloud storage afterwards).
