More on returning fine tuning (but we're treating different shifts of the same pitch as different notes at the moment which is not right)

function  [Pre,Rec,F]  = batchProcessingEvaluate(folder)

% Evaluate transcription output, using onset-only note-based metrics
% e.g. [Pre,Rec,F]  = batchProcessingEvaluate('TRIOS-mirex2012-matlab');
