function InferenceDS = fixinfds(InferenceDS)

% FIXINFDS  Fix a user generated ("hand rolled") inference data structure to make sure it meets
%           the consistency requirements of all ReBEL inference algorithms. This function will not
%           clobber any predefined fields, it will however check for consistency and add other
%           required fields to InferenceDS that the user has not defined, or for which the default
%           settings are required.
%
%   InferenceDS = fixinfds(InferenceDS)
%
%   INPUT
%          InferenceDS        ReBEL inference data structure that has been "hand-rolled", i.e
%                             directly defined by the user and not generated by using GENINFDS.
%                             This data structure might not be completely consistent.
%
%   OUTPUT
%          InferenceDS

%--- Add some needed fields with default values that the user either forgot to add, or intentionally
%--- left blank in order to set default values:

if ~isfield(InferenceDS,'type')
  InferenceDS.type = 'InferenceDS';
end

if ~isfield(InferenceDS,'stateAngleCompIdxVec')
  InferenceDS.stateAngleCompIdxVec = [];
end

if ~isfield(InferenceDS,'obsAngleCompIdxVec')
  InferenceDS.obsAngleCompIdxVec = [];
end

consistent(InferenceDS,'InferenceDS');
