tomwalters@0: Getting started with AIM-MAT
tomwalters@0:
tomwalters@0: AIM-MAT v 1.5
tomwalters@0: $Date: 20011-04-06 $
tomwalters@0:
tomwalters@0:
tomwalters@0: - To install AIM-MAT, recursively add the aim-mat,
tomwalters@0: tools and demo
tomwalters@0: folders to your MATLAB path
tomwalters@0: - To test the installation, run demo_aim2006_gtfb
tomwalters@0: from the demo folder, this
tomwalters@0: runs the analysis of the four scaled vowel sounds seen in the documentation.
tomwalters@0: The script opens six figure windows, one for each stage of the model, and
tomwalters@0: plots the output of each stage for the four vowels.
tomwalters@0: - To run AIM with a GUI type aim
tomwalters@0: at the prompt

tomwalters@0: System Requirements
tomwalters@0: AIM-MAT was developed using MATLAB 7 and above.
tomwalters@0: The package should work on any platform supporting MATLAB 6.5 or above, with
tomwalters@0: the Signal Processing Toolbox installed.
tomwalters@0: AIM-MAT has been tested while in development on the following platforms:
tomwalters@0: - Windows XP with MATLAB versions 6.5, 7.1, R2006a
tomwalters@0: - Mac OS X (version 10.4 onwards) with MATLAB version 7.1 and R2007b
tomwalters@0: - Ubuntu Linux with MATLAB versions 7.1, R2007b and R2008a

tomwalters@0: Tips for getting started
tomwalters@0:
tomwalters@0: - If AIM-MAT is started from the command-line with no parameters, a file-open dialogue box will be displayed. Select the .wav or .aiff file you wish to process using this box.
tomwalters@0: - AIM-MAT is a MATLAB implementation of the Auditory Image Model. The buttons
tomwalters@0: along the top of the main AIM-MAT window correspond to stages of this model.
tomwalters@0: The model runs from left to right across the window. The calculation of any
tomwalters@0: section of the model is contingent upon the calculation of the stage before
tomwalters@0: it.
tomwalters@0: - To enable any of the buttons at the top of the AIM-MAT window, simply check
tomwalters@0: the 'recalculate' checkbox below that button. This will automatically check
tomwalters@0: any other parts of the module that need recalculating.
tomwalters@0:
tomwalters@0: - If any section of the model needs calculating, the surround of the button
tomwalters@0: for that section will light up blue. If the section
tomwalters@0: needs recalculating the button surround will light up red.
tomwalters@0: Sections of the model which have been calculated have button surrounds in
tomwalters@0: dark green. The section whose output is currently
tomwalters@0: displayed has the button surround illumninated in bright
tomwalters@0: green.
tomwalters@0: - To get the contents of the AIM-MAT workspace into the MATLAB command line workspace at any point, simply select 'Copy current data to workspace (data)' from the 'Edit' menu.
tomwalters@0: - The plot window will show no activity for the first few frames of the output
tomwalters@0: of the SAI module. This is because it takes a finite time for the stabilised
tomwalters@0: image to build up. Use the 'Frame #' slider in the bottom left of the GUI
tomwalters@0: to move on a few frames and see the image to build up.
tomwalters@0: - The autoscaling function should scale each plot to a reasonable level, however,
tomwalters@0: if the activity in the plot window looks to large or too small, you can use
tomwalters@0: the 'autoscale' button to re-run the autoscaling, or use the scaling slider
tomwalters@0: to choose a suitable scale for the plot.
tomwalters@0: - AIM-MAT plots are just MATLAB figures; they can be manipulated using the
tomwalters@0: MATLAB 7 plot tools, or command line functions.
tomwalters@0: - AIM-MAT stores parameters for a processed file in a subdirectory of that
tomwalters@0: file's directory, named after the file without the extension. If you wish
tomwalters@0: AIM-MAT to start afresh on working on a file, delete this subdirectory.
