This file explains how the files and variables are structured. *_all_heatmaps.mat avrgheat = matlab structure AxBxC (A=tested levels; B=tested frequencies; C=tested individual + species mean + species median + species std) (values in microvolt) individuals = IDs of the tested individual + mean + median + std --> can be used as header for "avrgheat" indnum = number of individuals measured for this species species = measured species *_overall_threshold.mat individuals = frequencies IDs of the tested individual + species mean + species median + species std --> can be used as header for "thresholds" indnum = number of individuals measured for this species species = measured species thresholds = bootstrap threshold at each frequency for all individuals (given in dB level at which we measured) *_highResolution30.mat (measurement for a specific individual with a higher frequency resolution (i.e. 30 steps log. spread)) batid = individual ID of the tested bat out = matrix for ABR values (in microvolt) for measured 8 levels and 30 frequencies *_threshold_30.mat (measurement for a specific individual with a higher frequency resolution (i.e. 30 steps log. spread)) batid = individual ID of the tested bat result = bootstrap threshold (given in dB peSPL) at each measured frequency all_levels.mat list of all 12 tone pip levels (in dB peSPL) at which ABRs were measured all_freqs.mat list of all 11 frequencies (in kHz) at which ABRs were measured Call_freq_ranges.mat min and max frequency of the call types (in kHz) for all measured species (the order of species can be seen in "speciesnames")
