%% Resample Mass Spectrometry Data % This example shows how to resample mass spec data. % Copyright 2015 The MathWorks, Inc. %% % Load a MAT-file, included with Bioinformatics Toolbox(TM), % that contains mass spectrometry data, and then extract m/z and intensity % value vectors. load sample_hi_res; mz = MZ_hi_res; y = Y_hi_res; %% % Plot the original data. plot(mz, y, '.') %% % Resample the spectrogram to have 10000 samples between 2000 and maximum % m/z value in the data set, and show both the resampled and original data. [mz1,y1] = msresample(mz, y, 10000, 'range',[2000 max(mz)],'SHOWPLOT',true);
