# Make an environment for DAMNIT
git clone https://github.com/European-XFEL/DAMNIT.git
cd DAMNIT
conda create -n amore python

conda activate amore
pip install .

Copy context.py to new folder (e.g. within proposal usr or scratch). This 'context dir' is also where it will save selected data. Edit context.py to define what data is interesting.

To listen for new runs and extract data:

conda activate amore
cd /path/to/proposal/scratch/amore  # Context directory
amore-proto proposal 1234
amore-proto listen .

The backend will write its logs to stdout, and also a file called amore.log in the same directory.

To launch the GUI overview (e.g. on max-exfl-display):

conda activate amore
amore-proto gui

You can open the context dir inside the GUI ('autoconfiguration'), or pass it at the command line.

The GUI is updated by Kafka messages sent by the backend. Currently we use XFEL's internal Kafka broker at exflwebstor01.desy.de:9102, but this is only accessible inside the DESY network.

DAMNIT can run offline, but if you want updates from the backend and you're running DAMNIT outside the network and not using a VPN, you'll first have to forward the broker port to your machine:

ssh -L 9102:exflwebstor01.desy.de:9102 max-exfl.desy.de

And then add a line in your /etc/hosts file to resolve exflwebstor01.desy.de to localhost (remember to remove it afterwards!):

127.0.0.1 exflwebstor01.desy.de

And then DAMNIT should be able to use XFELs broker. If you want to use a specific broker you can set the AMORE_BROKER variable:

export AMORE_BROKER=localhost:9102

DAMNIT will then connect to the broker at that address.

DAMNIT is deployed in a module on Maxwell:

$ module load exfel amore

There was an idea in the beginning to potentially have multiple submodules for different instruments depending on how many people worked on features for instruments simultaneously, but so far we've just stuck with a single submodule for MID, exfel amore/mid, which is loaded by default with exfel amore. To update the module:

$ ssh xsoft@max-exfl.desy.de

# Helper command to cd into the module directory and activate its environment
$ amoremod mid
$ git pull # Or whatever command is necessary to update the code

# Only necessary if updating dependencies since DAMNIT is installed in editable mode
$ pip install -e .
