bvreader

Documentation

This crate provides a basic reader for BrainVision Recorder Files (.vhdr/.vmrk/.eeg)

ONLY FOR HEADER VERSION 1.0

Does not include full list of options but is extendable.

In order to keep it simple all types (FLOAT32, INT32, INT16) convert to f32.

Usage

use crate::bvreader::bv_reader::BVFile;

let headerfile = "src/bv_reader/data/testfiles/01_header.vhdr";
let metafile = BVFile::from_header(headerfile).unwrap();

// metafile.bv_header       contains the struct with header information
// metafile.bv_data         contains the data and some extra information
// metafile.bv_marker       contains the marker events

// metafile.bv_data.data    contains the sample values in a vec of channels, that each contain a vec of sample values as f32.

// scale data according to the resolution
let _ = metafile.bv_data.scale_channels(&metafile.bv_header.channel_info).unwrap();

Todos

1. Decode Timecode in marker new segment

2. .ini based parser instead of regex?

3. more options from specification

4. Validators for Header and Data not implemented.
