Basic ROOT Tutorial Collaboration Meeting Jun2019

Tutorial Session Goal =

The goals of each session should be clearly defined at the top of the page; for instance In this Tutorial you will learn how to analyze TTree data produced by TrkAna

Session Prerequisites and Advance Preparation

This tutorial may require attendees to have already completed other tutorials, and may require special preparations on their laptop. Prerequisites and advanced preparations should be listed at the top of the session, together with links. Examples might be:

• Perform the tutorial on running Mu2e art Framework jobs Tutorial_2019_June:Framework_jobs
• Read the root documentation on histogram fitting
• Download and install root (v6.14 or later) on your machine
• Run the root combined fit tutorial
• Install the following docker containers ()

Session Introduction

• Plan on spending 5 minutes in the beginning making sure everyone has fulfilled the prerequisites and has performed the advance preparation.
• If necessary, present a brief (~5 minutes) overview on goals, background information, and context. Make sure to link the slides to the session page.

Exercises

The majority of the session time should be spent performing exercises, which you link or embed in the session page.

• Each exercise should have a title; ie Create a histogram of the reconstructed Ce momentum
• Exercises may be chained (ie the output of the first is used as input to the next), but in that case make sure the output is also part of the downloads, so people who failed at step 1 can continue with the subsequent steps. Design this so that a failed step 1 does not overwrite the downloaded file that is the input to step 2.
• Some steps may take considerable processing time. In that case, have your attendees perform a short version (ie process 10 events), and provide the full output (ie histograms from 10^5 events) as part of the session download for subsequent steps.
• Each exercise should take between 5 and 15 minutes to complete. Count on your attendees taking twice as much time as would an experienced person.
• Start each exercise by bringing the exercise up on the main screen and going through its intro.
• Perform each step of the exercise on the screen, describing any decisions or issues involved as you do it. Check with your audience to make sure most (preferably all) have finished each step before going on to the next. If someone seems stuck, assign a session helper to help them individually and move on.
• It's OK to provide more exercises than most people will complete during the tutorial; they can be completed as homework.

Session Organization Guideline

• Encourage your attendees to ask questions if they are unsure what to do.
• You may or may not have session helpers, who have already performed the tutorial
• If someone finishes a step or exercise early, have them look around for neighbors that need help.
• If someone is stuck, have them raise their hand to get help.
