MVD-tool
Information
A simple C++ parser and tool for the MVD3 and Sonata neuroscience file formats
- provide a tool to convert MVD2 to MVD3
- provide a tool to export MVD to CSV
- provide a simple header base parser for MVD2
- provide a parser based on the HighFive library for MVD3 and Sonata
It also provides a high level Python API for parsing MVD3 and Sonata files.
Compilation
Prerequisites
- CMake >= 3.0
- GCC >= 4.9
- BOOST >= 1.41
- HighFive
- libSONATA
Compile and Install the C++ parser
mkdir build; pushd build
cmake ../ -DCMAKE_INSTALL_PREFIX=<install_dir>
make
make install
Compile and Install the Python API
python setup.py install
Examples with the Python API
Reading Sonata files
import mvdtool
node = mvdtool.open("tests/nodes.h5")
# retrieve data for the full range
node.morphologies()
# retrieve data for a certain range
node.morphologies([0, 1, 3])
Reading MVD3 files
import mvdtool
mvd = mvdtool.open("tests/circuit.mvd3")
mvd.morphologies()
Certain attributes in MVD files require the information from the mecombo file. In this case, it's strictly necessary that the mecombo file contains all combos from the MVD file.
mvd_tsv = mvdtool.open("tests/circuit_tsv.mvd3")
mvd_tsv.open_combo_tsv("tests/mecombo_emodel.tsv")
mvd_tsv.emodels()
