Open Microscopy Environment

We're running into issues running some pre-packaged scripts on Omero. They seem to be throwing "No Processor Available" errors which doesn't seem to make a lot of sense.

Here is the stack trace on Omero.insight:

Exception in thread "AWT-EventQueue-0"

Do you have access to the OMERO server logs? If not, could you ask your system administrator to get in touch with us? The fact that no processors are running on the server means that no scripts can be run. Likely a restart will be necessary. With server logs, we can hopefully tell you more.

Sorry for the troubles,
