A data frame containing synapse locations and metadata for 5 LHPD2a1 neurons from the BANC connectome dataset. Each row represents a single synapse with its 3D position and pre/post synaptic classification.
Format
A data frame with columns:
- connector_id
Unique identifier for the synapse connector
- pre_id
Pre-synaptic neuron ID
- post_id
Post-synaptic neuron ID
- prepost
Binary indicator: 0 for presynaptic (output), 1 for postsynaptic (input)
- pre_svid
Pre-synaptic supervoxel ID
- post_svid
Post-synaptic supervoxel ID
- size
Size of the synapse
- X, Y, Z
3D coordinates of the synapse in nanometers
- treenode_id
Node ID on the skeleton where this synapse is located
- root_id
The root ID of the neuron this synapse belongs to
