1 function test_IC_DominikaTones
2 % test_MAP1_14 is a general purpose test routine that can be adjusted to
3 % test a number of different applications of MAP1_14
4 %
5 % A range of options are supplied in the early part of the program
6 %
7 % One use of the function is to create demonstrations; filenames <demoxx>
8 % to illustrate particular features
9 %
10 % #1
11 % Identify the file (in 'MAPparamsName') containing the model parameters
12 %
13 % #2
14 % Identify the kind of model required (in 'AN_spikesOrProbability').
15 % A full brainstem model (spikes) can be computed or a shorter model
16 % (probability) that computes only so far as the auditory nerve
17 %
18 % #3
19 % Choose between a tone signal or file input (in 'signalType')
20 %
21 % #4
22 % Set the signal rms level (in leveldBSPL)
23 %
24 % #5
25 % Identify the channels in terms of their best frequencies in the vector
26 % BFlist.
27 %
28 % Last minute changes to the parameters fetched earlier can be made using
29 % the cell array of strings 'paramChanges'.
30 % Each string must have the same format as the corresponding line in the
31 % file identified in 'MAPparamsName'
32 %
33 % When the demonstration is satisfactory, freeze it by renaming it <demoxx>
