=========
PCs
=========

Grappa can be accessed from anywhere using your login credentials & ssh key.
icehap-daq can be accessed directly from the local network via: icehap-daq@10.25.121.183.
If you're outside the university network, access icehap-daq via Grappa.
The password for icehap-daq is the standard ICEHAP Lab password.

=========
Software
=========

The primary software repo (degg_measurements) is usually located under 'software'.
On icehap-daq: ``/home/icehap-daq/software/degg_measurements``.
On Grappa: ``/disk20/fat/software/degg_measurements``.

Data lives in the corresponding ``/data`` directories.
In data, you can find both ``json`` and ``fat_calibration``.
Meta-data files (as explained in previous sections) are found in ``json``.
Unprocessed files are in ``fat_calibration``.
When the data lives on icehap-daq, this is the "local" data, on Grappa it's the "remote".

======
Screen
======

There are already some previous tips about how to use screen, but I'll repeat them here.
On icehap-daq the DAQ script and setup run in screen sessions.
On Grappa, the remote analyses run in screen sessions.
You can check the screens available with ``screen -ls``, and attach to them with ``screen -r <name>``.
Once in a screen, detach with 'control+a', and then 'd'.
Screen sessions only keep a limited amount of previous lines in memory, you can access some of them by doign 'control+a', then 'escape'.
Navigate with the up and down arrow keys.
Otherwise the screen sessions operate as normal terminals.

On Grappa, the analysis screen sessions are logged in ``/disk20/fat/data/logs``.
