%%
% Load and plot a sample mass spectra data.
load sample_lo_res
msviewer(MZ_lo_res, Y_lo_res)

%%
% Add a marker by pointing to a mass peak, right-clicking, and
% then clicking *Add Marker*.

%%
% The *File* menu has the following options.
% 
% * *Import Markers from Workspace* - Opens the Import Markers From MATLAB(R)
% Workspace dialog. The dialog displays a list of double Mx1 or 1xM
% variables. If the selected variable is out of range, the viewer displays
