About This Release
------------------

This is a new release of the FaT, containing the following packages:
1) the FaT for Matlab 1.1

The Matlab toolbox package is unchanged from the previous release. It is a 
collection of functions and scripts for integrated analysis of 
faceLAB log file data with world models.

The FaT contains two parts:
	1. A standalone data browser compiled from Matlab and
	   released with faceLAB.
	2. Matlab source code functions and scripts.


2) xlFaT 1.1	
 
This is a new package introducing some of the Matlab data analysis 
functionality to the Excel environment as an add-in. 

The xlFaT was created with the Excel Builder MATLAB Toolbox
provided by the Mathworks (www.mathworks.com).



Summary of functions in the FaT
------------------------------------------
* Convenient data visualization using editable windows into 
  multidimensional data structures

* Post-experimental world model editing using gaze data and 
  3D to 2D projection

* Data summary and analysis by distributing grouping

* Fixation sequence and fixation map display


Summary of functions in the xlFaT
------------------------------------------
* Import faceLAB log file data from a .fll file

* Signal Viewer - which allows the user to zoom into a subset of
  the domain of a number of signals.

* Histogram Viewer - displays 2D histograms of pairs of signals
  and exports images.
   
* Histogram Editor - allows editing of the time series signals
  from the histograms.

* World Model Editor - provides an interface to edit world model
  parameters while superimposing the world model objects on recorded
  gaze, attention, or head pose data.

* Binary Signal Filter - Signal types can be used to remove data 
  from another signal with the signal filter, replacing values with 
  zeros or NaN symbols.

* Extraction Fixations - reduces data to mean values over the period
  of a fixation using a saccade flag.

* Summarizing Intersection Data - reduces the list of intersections for
  fixations into two tabes, listing characteristics of the intersections
  with each object and the transition between objects.

* xlFaT - online help on the functions described above, in tutorial
  like format.

-------------------
The FaT 1.2 requires:

* Matlab Release 12 or later to use the FaT for Matlab
