+function testBM (BMlocations, paramsName,...
+    relativeFrequencies, AN_spikesOrProbability, paramChanges)
+% testBM generates input output functions for DRNL model for any number
+% of locations.
+% Computations are bast on a single channel model (channelBFs=BF)
+% peak displacement (peakAmp) is measured.
+%  if DRNLParams.useMOC is chosen, the full model is run (slow)
+%  otherwise only DRNL is computed.
+% Tuning curves are generated based on a range of frequencies reletove to
+% the BF of the location.
