msviewer
Explore mass spectrum or set of mass spectra
Syntax
msviewer(
MZ
, Intensities
)
msviewer(..., 'Markers', MarkersValue
)
msviewer(..., 'Group', GroupValue
)
Arguments
MZ | Column vector of common mass/charge (m/z)
values for a set of spectra. The number of elements in the vector
equals the number of rows in the matrix Intensities . |
Intensities | Matrix of intensity values for a set
of mass spectra that share the same m/z range. Each row corresponds
to an m/z value, and each column corresponds to a spectrum or retention
time. The number of rows equals the number of elements in vector MZ . |
MarkersValue | Column vector to specify a list of marker
positions from the mass/charge vector MZ . |
GroupValue | Either of the following:
[1:numSpectra] . |
Description
msviewer(
displays
the MS Viewer, which lets you view and explore a mass spectrum defined
by MZ
, Intensities
)MZ
and Intensities
.
msviewer(..., 'Markers',
specifies
a list of marker positions from the mass/charge vector, MarkersValue
)MZ
,
for exploration and easy navigation. Enter a column vector with MZ
values.
msviewer(..., 'Group',
specifies a group to which the spectra belong. The groups are specified by
GroupValue
)GroupValue
, a vector of values or cell array of character
vectors or string vector. The number of values or character vectors or strings is the
same as the number of rows in the matrix Intensities
. Each
value or character vector specifies a group to which the corresponding spectrum belongs.
Spectra from the same group are plotted with the same color. Default is
[1:numSpectra]
.
The MS Viewer includes the following features:
Plot mass spectra. The spectra are plotted with different colors according to their group labels.
An overview displays a full spectrum, and a box indicates the region that is currently displayed in the main window.
Five different zoom in options, one zoom out option, and a reset view option resize the spectrum.
Add/focus/move/delete marker operations
Import/Export markers from/to MATLAB® workspace
Print and preview the spectra plot
Print the spectra plot to a MATLAB Figure window
MSViewer has five components:
Menu bar: File, Tools, Window, and Help
Toolbar: Move marker, Zoom XY, Zoom X, Zoom Y, Zoom out, Reset view, and Help
Main window: display the spectra
Overview window: display the overview of a full spectrum (the average of all spectra in display)
Marker control panel: a list of markers, Add Marker, Delete Marker, up and down buttons
