MVD version 2

Warning

This file format is deprecated and has been superseded by the SONATA Node File.

The circuit.mvd2 file contains metadata regarding the cells in the network and minicolumn metadata

File Format

Anything starting with # is a comment The first 2 lines after the comments at the begining of the mvd2 file are reserved for TBD.

No counts are given. Parsing is done by reading rows after a given section label until a different section label is encountered. Section labels: ‘Neurons Loaded’, ‘MicroBox Data’, ‘MiniColumnsPosition’, ‘CircuitSeeds’, ‘MorphTypes’, ‘ElectoTypes’
