[ome-devel] Channel data from Matlab

[Dan Withey]

Hello,
 
Is there a way to access image channel data using Matlab? When attempting this, the following error is reported:
 
Error using omero.model.PixelsI/getChannel
Java exception occurred:
omero.UnloadedCollectionException: Error updating collection:channelsSeq
Collection is currently null. This can be seen
by testing "channelsSeqLoaded". This implies
that this collection was unloaded. Please refresh this object
in order to update this collection.
 
Here's the code:
 
client = loadOmero(url); 
 
session = client.createSession(user, password);
gateway = session.createGateway();
timer = omeroKeepAlive(client); % Creates and starts a 60 second timer.
userId = session.getAdminService().getEventContext().userId;
 
ContainerProxy = session.getContainerService();
 
params = omero.sys.ParametersI();
params.leaves();%indicate to load the images
params.exp(omero.rtypes.rlong(userId));
 
projectsList = ContainerProxy.loadContainerHierarchy(char('omero.model.Project'), [], params);
p = projectsList.get(0);
 
datasetsList = p.linkedDatasetList;
d = datasetsList.get(0);
 
imageList = d.linkedImageList;
image = imageList.get(0);
 
pixelsList = image.copyPixels();
pixels = pixelsList.get(0);
 
pixels.getChannel(0);
 
Thanks!
Dan
