Old notes:
------------------
Starting from this page:
  https://redmine.jlab.org/projects/podd/wiki/Workshop2018
In general, items with a (*) on that page denotes an interactive
tutorial component.  If you login to Bluejeans via:
  https://jlab.bluejeans.com/
then you can view the recorded video sessions.

Review the following presentations first:
  - Farm Use and Computing Resources Tips and Tricks -- Brad Sawatzky
  - Overview & Update of the Hall C Analyzer -- Eric Pooser
  - Eric's talk from the 2019 Hall C Winter Collab meeting is also quite
    useful:
  https://www.jlab.org/indico/event/296/session/11/contribution/12/material/slides/0.p

Then move on to the Tuesday 'Hall C' sessions starting with the git
howto:
  - Effective Git use (*) -- Steve Wood
Folks really do need to understand how to work with git.  They should
follow up on the tutorials/howtos Steve mentions in his talk before
moving on.

If you want a space to work, log on to the ifarm and create a directory
under /group/c-polhe3/Users/.  For example:
  % cd /group/c-polhe3/Users/
  % mkdir brads   ## change 'brads' to your username
  % cd brads      ## change 'brads' to your username

If you want to follow along with the interactive sessions, the you can
get the VM (virtualbox) setup working.  Most of the interactive 'howtos'
are in the Tuesday afternoon session.  Ole's talks are likely a good
place to start with the VM.  The video recordings may be of particular
use here.
  14:30 Reading and processing trees (part2) (*) -- Ole Hansen

Next level analysis would include working through the 'Hall C Analysis'
talks in the Tuesday morning session.  They are on calibration tasks
that we will need to perform ourselves.  They also outline how the
various detector maps, cut, and def files interact.  (This is the kind
of information I would like to get consolidated in a set of new 'howto'
pages on the wiki.)

All the software and steps outlined on the "old" pages will match
what we will do very closely, so it is *not* wasted time to start
with the above documentation.

For those of you who can get started on a Detector Calibration
procedure, you can start editing this page:
  https://hallcweb.jlab.org/wiki/index.php/Polarized_Helium-3_Experiments
If you have files/scripts that are not already online as part of a of a
git repo, or similar, then you can copy them into a new folder here:
  /group/c-polhe3/Calibration_scripts-temp/
Be sure you put a README file in there too that says who you are, and
where you got the scripts from.

* Note that all of the calibrations steps have already been done by
* existing groups in Hall C!  Talk to folks on the previous experiments
* (if that isn't you) and have them show you the documentation and notes
* they already have.  Start with just getting those notes linked to this
* page.  If different groups have different procedures, you can provide
* links/references to both.

Clean up / consolidation will be the next step.
