%DATA_BAUMGARTNER2016 Data from Baumgartner et al. (2016)
% Usage: data = data_baumgartner2016(flag)
%
% Output parameters:
% data : data structure
%
% The data structure contains the following fields:
%
% 'id' listener ID
%
% 'S' listener-specific sensitivity parameter
%
% 'mrs' listener-specific task-induced response scatter (derived
% from central lateral response precision in baseline condition)
%
% 'Obj' DTF data in SOFA Format
%
% 'pe_exp' experimental local polar RMS error
%
% 'qe_exp' experimental quadrant error rate
%
% 'target' experimental target angles
%
% 'response' experimental response angles
%
% 'itemlist' experimental item list.
%
%
%
% The Columns of .itemlist denote:
% [azi_target, ele_target, azi_response, ele_response, lat_target, pol_target, lat_response, pol_response, F/B-Confusion resolved pol_response]
%
%
%
%
% If the 'model'-flag is set the output contains also the following fields
%
% 'S' listener-specific sensitivity parameter.
%
% 'Obj' DTF data in SOFA Format.
%
% 'pe_exp' experimental local polar RMS error in baseline condition.
%
% 'qe_exp' experimental quadrant error rate in baseline condition.
%
% 'target' experimental target angles.
%
% 'response' experimental response angles.
%
% 'stim' target stimulus.
%
% 'fsstim' sampling rate of target stimulus.
%
% DATA_BAUMGARTNER2016(flag) returns data from Baumgartner et al. (2016)
% describing a model for sound localization in sagittal planes (SPs)
% on the basis of listener-specific directional transfer functions (DTFs).
%
% DATA_BAUMGARTNER2016 accepts the following flags:
%
% 'baumgartner2014' data of the pool from Baumgartner et al. (2014). This is the default.
% 'Long' 300ms at 50+-5dB SL.
% '10dB' 3ms at 10+-5dB SL.
% '20dB' 3ms at 20+-5dB SL.
% '30dB' 3ms at 30+-5dB SL.
% '40dB' 3ms at 40+-5dB SL.
% '50dB' 3ms at 50+-5dB SL.
% '60dB' 3ms at 60+-5dB SL.
% '70dB' 3ms at 70+-5dB SL.
% 'all' All conditions stated above. Itemlists in cell array.
% 'ConditionNames' To receive cell array with all condition names.
%
% 'model' DTFs, sensitivities and test stimuli necessary for model
% predictions. Sensitivity paramters will be calibrated if
% calibration data does not exist or does not match the
% current setting of baumgartner2016.
%
%
% Requirements:
% -------------
%
% 1) SOFA API from http://sourceforge.net/projects/sofacoustics for Matlab (in e.g. thirdparty/SOFA)
%
% 2) Data in hrtf/baumgartner2014 and hrtf/baumgartner2016
%
% 3) Data in auxdata/baumgartner2016
%
% Examples:
% ---------
%
% To get all listener-specific data of the pool from Baumgartner et al. (2014), use:
%
% data_baumgartner2016;
%
% To get all listener-specific data of the LocaLevel study, use:
%
% data_baumgartner2016('Long');
