[Homer-users] RE: Inquiry on exporting image

[Huppert, Ted]

If you open a *.fig file in matlab, you can access any of the data stored in the figure using the "children" functions.  For example:

open('myFig.fig');
children=get(gca,'children');
for idx=1:length(children)
            try
                        xdata=get(children(idx),'xdata');
ydata=get(childen(idx),'ydata');
catch
disp('This child is not a line object, there is no data for this child- skipping...');
end
end

The trick is that you need to figure out the order of the children and which one is the data you want.  I typed this directly into this email- so pardon me if this doesn't run directly... but, you get the picture.

Note- that in HOMER, if you right click on a data line, you can directly copy that line's data to the clipboard or export just that data trace to an ASCII file.

Subject: [Homer-users] Inquiry on exporting image

Hi All,

I intend to export reconstructed images (HbO and Hb) into ASCII files so as to conduct various statistical analyses.

It looks like HomER just allows an image-style output (like .fig, .jpg, etc.), rather than a numeric fashion. Does anybody here happen to know a tricky way to convert the .fig file into an ASCII file?

I really appreciate any help in advance!
