USAGE 

  java Experiment <show clock?> <multiple> <n> <midi device> <scale length> <low anchor> <high anchor> <midi file directory> <instructions file> <results directory> <familiarity> <pleasantness> <questionnaire> <fullscreen> <debug>

where <show clock?> specifies whether to show the clock (0 = no; 1 =
yes) and <multiple> and <n> are integers: the clock runs for <n> time
units before a probed event where the time unit is a multiple of the
tatum as specified by <multiple>.

<midi device> is an integer specifying the midi device to use (usually 0) or a boolean String ("true" or "false") where "true" specifies that the program should use the default midi device and "false" specifies that the program should not use the default midi device, and should list the available midi devices on start up.

<scale length> is the number of levels of the rating scale and <low
anchor> and <high anchor> are its high and low anchors respectively
(e.g., "highly unexpected", "highly expected" with a scale length of
7). 

<midi file directory> is the directory where the midi files are stored

<instructions file> is an html file containing the instructions for
the participant which will be displayed at the beginning of the
experiment.

<results directory> is the directory where the results will be written.

If <familiarity> is 1 the participant is asked to rate the familiarity
of each stimulus, if it is 0 the question is omitted.

If <pleasantness> is 1 the participant is asked to rate the pleasantness
of each stimulus, if it is 0 the question is omitted.

if <questionnaire> is 1, experiment ends with a compulsory
questionnaire on age, sex, musical training etc.; if it is 0 the
questionnaire is optional.

If <fullscreen> is 1, the program will produce a fixed full screen GUI which can't be resized if the device allows this; if it is 0 then the program will produce a resizable full screen GUI.

if <debug> is 1 debug information is written to the terminal, if 0 it is not.

See runExperiment.bat for an example.

To use in a study:

1. put the relevant midi files in the directory specified by <midi
file directory>. When playing the clock, the program can be a little 
fussy about the onsets and durations of the notes in the midi files 
being exact integer multiples of each other. 

2. edit pfilelist.txt and filelist.txt (also in <midi file directory>)
to contain the midi files played in the practice and main blocks
respectively: put one file on each line followed by a list of note
numbers to probe with the visual clock (e.g., 1 = the first note). 
NB: only use a single space between filenames and note numbers; 
also, the last line of these files must terminate with a newline.

3. create a set of instructions for the study in an html file.

The results are written to files in the specified directory which must
exist.

4. responses can be given either using the mouse or using the numeric
keys (except in the case of a scalelength of 2 where the keys 'q' and
'p' are used).

             - MelodyResults.java   
             - SubjectResults.java
             - Block.java 

View:       ExperimentGui.java
