[ome-devel] Setting the channel ID/name from Matlab - Help!

[Jean-Marie Burel]

Hi Ian

If you want to set the name of the channels, you need to modify the
logical Channels.

Follow some code
Assuming that you have the imageID available.

% Retrieve an image if the identifier is known.
    proxy = session.getContainerService();
    list = proxy.getImages(omero.model.Image.class,
java.util.Arrays.asList(imageId), omero.sys.ParametersI());
    image = list.get(0);

    % Access information about the image for example to draw it.

    % The model is a follow: Image-Pixels i.e. to access valuable data
about
    % the image you need to use the pixels object.
    % We now only support one set of pixels per image (it used to be
more!).

    service = session.getPixelsService();
    Update = session.getUpdateService();
    pixelsList = image.copyPixels(); % should only be one.
    for k = 0:pixelsList.size()-1,
       pixels = pixelsList.get(k);
       % retrieve information about the pixels.
       pixels = service.retrievePixDescription(pixels.getId().getValue());
       channels = pixels.copyChannels();
       for j = 0:channels.size()-1,
           c = channels.get(j);
           c.getLogicalChannel().getName().getValue(); % to read the value
           % to save
           c.getLogicalChannel().setName(omero.rtypes.rstring(NEW_NAME));
           %update.saveAndReturnObject(c.getLogicalChannel()); better to
save all channels in one go.
       end
    End


I will add that example to the page.
