Accessing FlyWire Proofread Reconstructions with CloudVolume

FAFB_data.py

from cloudvolume import CloudVolume

cv = CloudVolume(
    'graphene://https://fafbv2.dynamicannotationframework.com/segmentation/1.0/fly_v31',  # neuroglancer layer
    use_https=True # uses the public access interface
)

# Download and Save a Mesh to Disk
mesh = cv.mesh.get(720575940621065107)
with open('720575940621065107.ply', 'wb') as f:
  f.write(mesh.to_ply())

# Extracting a Volumetric Image Label from an ROI
img = cv.download_point( 
  (161493, 46884, 2759), # point in neuroglancer
  segids=[ 720575940627678160 ], 
  mip=0, size=(256, 256, 256),

)

Requires cloud-volume >= 0.61.0

For installation instructions, check out the main CloudVolume repository here:

pip install cloud-volume usually suffices though.
