Recent Files
A list of recent files is available under Recent Files in the File menu. This has a list of files that were opened using the Open File command.
Files added to this list will not appear automatically if the application is closed and reopened. They must be saved by using the Save Settings menu item under Settings.

Data Sources
EVIO Data Source
EVIO files can be loaded using the Open File menu item under File. These events will be processed using the currently configured event builder to produce in-memory LCIO events which can then be reconstructed.
LCIO Data Source
LCIO files can also be loaded using Open File. These files may contain only the data collections, in which case reconstruction steering should be run. Or these files may already contain reconstruction output.
ET Server
Data can be read from an ET server (also called ET ring) and converted to EVIO.
A local ET ring can be started from the command line.

|---|---|---|---|---|

java -Xmx2g -cp ./distribution/target/hps-distribution-bin.jar org.jlab.coda.et.apps.StartEt -f ETBuffer -s 20000 -v |
Then the EVIO file can be streamed to the ET server using a utility in HPS Java.
| Code Block | ||||
|---|---|---|---|---|

java -cp ./distribution/target/hps-distribution-bin.jar org.hps.record.evio.EvioFileProducer -e events.evio -f ETBuffer |
In real data taking, the monitoring application will need to be configured to connect properly to the Counting House's ET ring.
