NAME

eegdev-open-options - Device configuration format specification

DESCRIPTION

Syntax of the configuration string

The device configuration string should follow the syntax:
 
device[[|option1|value1]...[|optionN|valueN]]
 
If the specified device does not support a certain pair of option|value, this will be silently ignored by the opening function. device should be the name of a eegdev plugin or any. In the later case, it will try to open one of the devices supported by the installed plugins.

Syntax of the configuration files

The configuration files are made of statements (at most one per line) following this syntax (whitespace are ignored):
 
option = value
 
Comments are preceded by the '#' character:
 

# comment line 1
# comment line 2
option = value #comment2

FILES

/etc/eegdev/eegdev.conf
Shared configuration file.
/etc/eegdev/<plugin>.conf
Configuration file loaded when the plugin <plugin> is used. The settings specified here overrides the settings in the shared configuration file.

EXAMPLES

Configuration string examples

Device sourcing its data from the GDF file located at "/home/user/data.gdf":
 
datafile|path|/home/user/data.gdf
 
Biosemi device configured to use 32 electrodes:
 
biosemi|numch|32
 
gTec system consisting in a chain of 2 systems (the first 2 available) with a notch filter at 60Hz without lowpass or highpass sampling at 512Hz (default sampling rate):
 
gtec|notch|60|lowpass|none|highpass|none|deviceid|any+any
 
Any supported type of device but should have the serial number UB-2009.10.06 if it is a gTec system:
 
any|deviceid|UB-2009.10.06
 

Configuration file example


# gTec configuration examples
notch  = 60 # Notch value for USA
lowpass =none
highpass=none
# Specify a coupled system by default deviceid = any+any
