funlib.show.neuroglancer

Scripts and helpers for the neuroglancer WebGL viewer.

Currently contains:

• a layer to show multi-scale volumes from python
• a modified video_tool.py to work with LocalVolume
• a convenience method to add daisy-like arrays to a neuroglancer context

Usage

You can use terminal glob syntax to select multiple volumes for visualization:

neuroglancer path/to/your/data.zarr/and/volumes/*

Extra optional arguments are:

• --no-browser
• --bind-address
• --port

We also have slicing support (This command will select only the first channel of raw from every crop):

neuroglancer data.zarr/crop_*/raw[0]

This can lead to a conflict if you want to use glob expansion to select multiple arrays. Here it is unclear if you want to visualize the arrays raw_1, raw_3, raw_4 and raw_5, or if you want to visualize channel 1345 of the array raw_.

neuroglancer data.zarr/raw_[1345]

To make this less ambiguous, we allow the use of the : character to separate the array glob from the slicing patter. So the following command will select the arrays raw_1, raw_3, raw_4 and raw_5:

neuroglancer data.zarr/raw_[1345]:
