Brion

Brion provides two libraries Brion and Brain. The former is a collection of file readers and writers intended for low level access to the data model. The latter is a set of higher level classes that wrap low level data objects with a use-case oriented API.

IO library

This is the core library provided by Brion. It includes classes for reading and writing files which store the Blue Brain data model.

• Fast and low-overhead read access to:
  • Blue configs (brion::BlueConfig)
  • Circuit description (brion::Circuit)
  • H5 Synapses data (brion::SynapseSummary, brion::Synapse)
  • Target (brion::Target)
  • BBP binary meshes (brion::Mesh)
  • BBP H5 morphologies and SWC morphologies (brion::Morphology)
  • Compartment reports (brion::CompartmentReport)
  • Spike reports (brion::SpikeReport)
• Fast and low-overhead write access to:
  • Compartment reports (brion::CompartmentReport)
  • BBP binary meshes (brion::Mesh)
  • BBP H5 morphologies (brion::Morphology)
  • Spike reports (brion::SpikeReport)
• Basic data types to work with the loaded data using Boost, Lunchbox

High level library

The higher level library is called Brain and it provides:

• brain::Circuit to facilitate loading information about cells, morphologies (in local and global circuit coordinates) and synapses.
• brain::neuron::Morphology with higher level functions to deal with morphologies.
• brain::Synapses and brain::Synapse for array and object access to synapses.
