sharplibeuropeandataformat's Introduction

Summary

SharpLibEuropeanDataFormat allows you to read EDF files typically used in medical applications. See EDF specification. Support for writing was left in place but is untested and most certainly broken.

This project is provided under the terms of the MIT license.

Binary Distribution

The easiest way to make use of this library in your own project is to add a reference to the following NuGet package.

European Data Format

Header

# Chars	File description
8 ascii	version of this data format (0)
80 ascii	local patient identification
80 ascii	local recording identification
8 ascii	startdate of recording (dd.mm.yy)
8 ascii	starttime of recording (hh.mm.ss)
8 ascii	number of bytes in header record
44 ascii	reserved
8 ascii	number of data records
8 ascii	duration of a data record, in seconds
4 ascii	number of signals (ns) in data record
ns * 16 ascii	ns * label (e.g. EEG Fpz-Cz or Body temp)
ns * 80 ascii	ns * transducer type (e.g. AgAgCl electrode)
ns * 8 ascii	ns * physical dimension (e.g. uV or degreeC)
ns * 8 ascii	ns * physical minimum (e.g. -500 or 34)
ns * 8 ascii	ns * physical maximum (e.g. 500 or 40)
ns * 8 ascii	ns * digital minimum (e.g. -2048)
ns * 8 ascii	ns * digital maximum (e.g. 2047)
ns * 80 ascii	ns * prefiltering (e.g. HP:0.1Hz LP:75Hz)
ns * 8 ascii	ns * nr of samples in each data record
ns * 32 ascii	ns * reserved

Data Record

# Chars	File description
nr of samples[1] * integer	first signal in the data record
nr of samples[2] * integer	second signal
..
..
nr of samples[ns] * integer	last signal

Publish

To publish a new release specify your version in Project\Lib\SharpLibEuropeanDataFormat.csproj and push the changes with a commit description such as: Release vx.y.z where x, y, z form your version number. That should publish it on NuGet providing that your secret NUGET_API_KEY is still valid.
