Usage

# initialize iLCSoft/key4hep
$ source /cvmfs/ilc.desy.de/key4hep/setup.sh

# compile this processor
$ mkdir build && cd build
$ cmake ..
$ make install -j20

# add processor to MARLIN_DLL
$ export MARLIN_DLL=$MARLIN_DLL:/path/to/source/lib/libTOFInfo.so

# run
$ Marlin ../xml/steer.xml

Event display

Open a terminal on the local PC and do:

$ source /afs/desy.de/project/ilcsoft/sw/x86_64_gcc75_ub1804/v02-02-02/init_ilcsoft.sh
$ glced -trust naf-ilc

Before running Marlin ../xml/steer.xml on the naf machine do:

$ export CED_HOST=your_local_machine_name
# e.g.
# export CED_HOST=flc19

I have added this for debugging purposes, to clearly see a track/hits. But the code will work without these steps just fine.

What is inside

It shows how to extract ECAL hits and track information you will need for training.

In this example I just print it in terminal, but you can dump it into any other format you like.

The most important code is inside:

printOutputFCN()
and
printOutputGNN()

they are executed inside processEvent() which is the main function which executes every event.

Output

After executing, this is the output example for printOutputFCN() with "Frank hits".

Note: you will need to scroll up a bit through the event display output.
