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 configura-
tion 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
