WHAT IS IT?

TEMPO (Topographic Eeg Mapping Program) is software for 3D visualization
of brain electrical activity.  TEMPO is able to read EEG recordings in
standard EDF format and to create animated sequence of 3D topographic
maps with EEG activity color-coded over scalp region.  The primary
strength of TEMPO approach to topographic mapping is ability to examine
the same map from different viewpoints - user is able to navigate around
head object using mouse.  Individual topographic maps could be saved in
PNG format for future examination.  The animation, as well as mapping
parameters, are controllable through corresponding graphical user
interface.


REQUIREMENTS

TEMPO is written in C, using OpenGL library for 3D graphics and GTK+
toolkit for GUI.  TEMPO project employs GNU autotools, so existence of
all necessary libraries will be checked during configure phase.


INSTALLATION AND USAGE

For detailed TEMPO installation instructions, see INSTALL document.  For
impatient, simple sequence of:
  ./configure
  make
  make install
will do the job.

The data subdirectory of TEMPO distribution contains 60s long sample EDF
recording (file sample.edf) of healthy female subject exposed to visual
alerting sequence.  This file is also installed along with other TEMPO
data files in appropriate system directory (/usr/local/share/tempo by
default, this could be changed during configuring phase).  This sample
could be used to try TEMPO; EDF filename to be mapped should be
specified when starting TEMPO as follows:
  tempo /usr/local/share/tempo/sample.edf
The button with right arrow icon will start animation, mouse dragging
while right button pressed could be used to rotate head model.  For
further instructions on using TEMPO, see on-line help (accessible
through Help button).


BUGS

EDF format is very flexible, that makes it hard for TEMPO to support all
possible variations of naming electrodes and utilizing other available
fields from EDF header.  So, if problems appear with some EDF data
files, please contact TEMPO maintainer.  Please also report other kind
of bugs to TEMPO maintainer.  See AUTHORS file in TEMPO distribution for
contact information.
