rmeddis@0: function test_MAP1_14
rmeddis@15: % test_MAP1_14 is a general purpose test routine that can be adjusted to
rmeddis@15: % test a number of different applications of MAP1_14
rmeddis@15: %
rmeddis@15: % A range of options are supplied in the early part of the program
rmeddis@15: %
rmeddis@15: % One use of the function is to create demonstrations; filenames <demoxx>
rmeddis@15: %  to illustrate particular features
rmeddis@15: %
rmeddis@15: % #1
rmeddis@15: % Identify the file (in 'MAPparamsName') containing the model parameters
rmeddis@19: %
rmeddis@15: % #2
rmeddis@15: % Identify the kind of model required (in 'AN_spikesOrProbability').
rmeddis@15: %  A full brainstem model (spikes) can be computed or a shorter model
rmeddis@15: %  (probability) that computes only so far as the auditory nerve
rmeddis@15: %
rmeddis@15: % #3
rmeddis@15: % Choose between a tone signal or file input (in 'signalType')
rmeddis@15: %
rmeddis@15: % #4
rmeddis@15: % Set the signal rms level (in leveldBSPL)
rmeddis@15: %
rmeddis@15: % #5
rmeddis@23: % Identify the channels in terms of their best frequencies in the vector
rmeddis@15: %  BFlist.
rmeddis@15: %
rmeddis@15: % Last minute changes to the parameters fetched earlier can be made using
rmeddis@15: %  the cell array of strings 'paramChanges'.
rmeddis@15: %  Each string must have the same format as the corresponding line in the
rmeddis@15: %  file identified in 'MAPparamsName'
rmeddis@15: %
rmeddis@15: % When the demonstration is satisfactory, freeze it by renaming it <demoxx>
