Can't connect to OMERO server

Hello,
I´m trying to connect the “OMERO Reader (5.2)” node to our OMERO server. I introduced the user credentials, but when I press the “start OMERO.insight” button it says "login failed.

I´m running KNIME v 3.7.0 on Windows 10, and OMERO server v5.4.5.

The output of the Knime.log is the following:

2019-01-16 10:32:38,385 : DEBUG : KNIME-Worker-8 : WorkflowManager : OMERO Reader (5.2) : 2:1 : OMERO Reader (5.2) 2:1 doBeforePostExecution

Looking to the log it´s looks like the node is properly configured, but I´ve got an error, and the OMERO.insight doesn´t open.

What I´m doing wrong?

Thank you.

Hi @_Itu,

The node that you are trying to use does currently not support OMERO 5.4.x. We are working on an updated version that does support the OMERO 5.4 release line. You can try out the latest, non-stable version of the OMERO integration by adding the Nightly Update Site to your KNIME Analytics Platform and installing KNIME Image Processing - OMERO Integration (0.20.1.201901160633 as of today).

Be warned that those nodes do not support OMERO.insight anymore (since its future is somewhat unclear).

Best regards,
Stefan

Thank you very much for your answer.
I´ve instaled the nightly build and now the “OMERO Conexion” node seems to conect correctly to the OMERO server, but i dont really understand how it works. I´ve also triedto the labeling and table reader nodes, but the intructions are not very clear.

Could you please tell me where I can find a description of how to use it?

Thank you,
Best regards

Hi @_Itu,
You need to connect the OMERO Connection node to a List Remote Files node:


you can then select a project or folder and it will create a list of all contained images.
You can then feed this list to the Image Reader Table (Remote) node together with the OMERO connection. The labeling reader can read the labelings attached to an image, it also consumes the URIs produced by List Remote Files node.
The table reader can read table attachments from OMERO, it requires the object id of the table which you can get from the OMERO web interface.

best,
Gabriel
