This repository (LocalConnectome/LC) contains structural/functional interrogations (including visualisations) of various connectome datasets (H01, LDC, ADC, CEC), and software used in their derivation.
The "Local Connectome" is taken as the connectivity data between those neurons (neuron_id) which have cell soma/centroids that reside within a connectome Release dataset. The local connectome is analysed along with its immediate incoming and outgoing connections.
With the expansion of the LC software to support multiple, complete brain datasets (LDC/ADC/CEC), the title of the repository "Local Connectome" now refers more generally to the local machine processing of connectome data.
Source datasets are from the H01 Release of the Petascale Reconstruction of the Human Cortex, as provided by The Lichtman laboratory at Harvard University and the Connectomics at Google team (https://h01-release.storage.googleapis.com/landing.html):

- gs://h01-release/data/20210601/c3/synapses/exported/json (https://h01-release.storage.googleapis.com/data.html)
Local connectome connections dataset [intermediary] as provided by Dr Yuelong Wu of The Lichtman laboratory (includes cell centroids and cell types, pre-post synaptic directionality encoded):
- in_body_cell_connection.csv
Local connectome somas dataset available from the bioRxiv v4 release of the H01 paper (includes cell centroids and cell types):
- somas.csv - gs://h01-release/data/20210601/c3/tables/somas.csv (https://h01-release.storage.googleapis.com/data.html)
The LCindexedCSVdatabase software was developed during the H01 bioRxiv v2 release, before the release of the official H01 local connectome somas dataset. Additional H01 Release datasets or updates thereto are expected. As of the bioRxiv v2 release of the H01 paper, the synapse predictions were still being refined and may be subject to future changes. The cell types, synapses types etc. were all generated by deep learning models trained by The Lichtman laboratory and their collaborators at Google, and they internally used Google BigQuery to share the data. Because the BigQuery tables are not discoverable by outside groups, they exported the synapse table to Avro format when releasing the data.
