LN-IO-h5-csv 1.0.0

LiveNodes: node based live streaming sensor/data and visualization suite.

LiveNodes IO H5 CSV

The LiveNodes IO H5 CSV package provides nodes for data input and output using HDF5/.h5 data files. Optionally, this also includes data annotations via .csv files.

For HDF5/.h5 data files, the expected format is a dataset named "data" with samples in rows and channels in columns.

For .csv annotation files, each line contains a triple of the start sample number, the end sample number (exclusive), and the respective annotation string. See the following example:

start,end,act
0,30,Stand
30,50,Walk
50,80,Run
80,100,Stand

Files created using the Out_h5_csv node automatically follow these formats.

Nodes in this package

Node	Purpose

Out_h5_csv	Writes data to HDF5/.h5 files and (optionally) annotation to .csv files.

About LiveNodes

LiveNodes are small units of computation for digital signal processing in python. They are connected multiple synced channels to create complex graphs for real-time applications. Each node may provide a GUI or Graph for live interaction and visualization.

Any contribution is welcome! These projects take more time, than I can muster, so feel free to create issues for everything that you think might work better and feel free to create a MR for them as well!

Have fun and good coding!
