rmeddis@36: function test_MAP1_14
rmeddis@36: % test_MAP1_14 is a general purpose test routine that can be adjusted to

rmeddis@36: % One use of the function is to create demonstrations; filenames <demoxx>

rmeddis@36: % #2

rmeddis@36: %  A full brainstem model (spikes) can be computed or a shorter model
rmeddis@36: %  (probability) that computes only so far as the auditory nerve
rmeddis@36: %
rmeddis@36: % #3
rmeddis@36: % Choose between a tone signal or file input (in 'signalType')
rmeddis@36: %
rmeddis@36: % #4
rmeddis@36: % Set the signal rms level (in leveldBSPL)
rmeddis@36: %
rmeddis@36: % #5
rmeddis@36: % Identify the channels in terms of their best frequencies in the vector
rmeddis@36: %  BFlist.

rmeddis@36: % Last minute changes to the parameters fetched earlier can be made using
rmeddis@36: %  the cell array of strings 'paramChanges'.
rmeddis@36: %  Each string must have the same format as the corresponding line in the
rmeddis@36: %  file identified in 'MAPparamsName'
