maimage - Spatial image for microarray data

Syntax

maimage(X, FieldName)
H = maimage(...)
[H, HLines] = maimage(...)

maimage(..., 'PropertyName', PropertyValue,...)
maimage(..., 'Title', TitleValue)
maimage(..., 'ColorBar', ColorBarValue)
maimage(..., 'HandleGraphicsPropertyName' PropertyValue)

Arguments

Description

maimage(X, FieldName) displays an image of field FieldName from microarray data structure X. Microarray data can be GenPix Results (GPR) format. After creating the image, click a data point to display the value and ID, if known.

H = maimage(...) returns the handle of the image.

[H, HLines] = maimage(...) returns the handles of the lines used to separate the different blocks in the image.

maimage(..., 'PropertyName', PropertyValue,...) defines optional properties using property name/value pairs.

maimage(..., 'Title', TitleValue) allows you to specify the title of the plot. The default title is FieldName.

maimage(..., 'ColorBar', ColorBarValue), when ColorBarValue is true, a color bar is shown. If ColorBarValue is false, no color bar is shown. The default is for the color bar to be shown.

maimage(..., 'HandleGraphicsPropertyName' PropertyValue) allows you to pass optional Handle Graphics^® property name/value pairs to the function. For example, a name/value pair for color could be maimage(..., 'color' 'r').

Examples

madata = gprread('mouse_a1wt.gpr');
maimage(madata,'F635 Median');
figure;
maimage(madata,'F635 Median - B635',...
        'Title','Cy5 Channel FG - BG');
