2022 COSS Bioinformatics

Bioinformatics is a multidisciplinary field that develops methods for turning the so-called biological big data into knowledge. Although most problems in biology are not as embarrassingly parallelizable as the physics codes that HPC systems are usually designed for, this has been starting to change in recent years. Metagenomics is an emerging field in bioinformatics that investigates microbes inhabiting oceans, soils, the human body, etc. with sequencing technologies. In this course, we will first tune your HPC knowledge/skills towards bioinformatics computing and then a typical metagenomics pipeline will be explored to introduce common tools used in bioinformatic analysis and to show how they can be run in an HPC environment.

This workshop will be delivered in 3 sessions:

  • Session 1: Monday, June 6, 2022 from 10:00 AM - 12:00 PM EDT

2022 COSS Introduction to R

This is a short course for beginners with no previous knowledge and experience of R. We will begin with loading a dataset in a CSV file into R and doing some basic statistics with the dataset. We then look into how to group those R commands into an R function to avoid typing commands repeatedly when we need to redo the calculations. We move on to show how to automate the process of loading a bunch of CSV files and perform the same statistical tasks with R built-in commands and for loops. Naturally we start looking into the fundamental concepts of R programming, with focus on manipulation of lists, vectors, arrays and data frames. As an important feature and strength in statistical computing, we give a very brief introduction to the random number generators and statistical functions. We touch upon linear regression with simple, easy to understand examples. While walking through examples with datasets, we will emphasize on the most commonly used data structure - data frames - and show by examples how to manipulate cells, rows and columns in data frames. At the end of the course, we will dive into the R package ggplot2 from the amazing R tidyverse collection for data science packages. We will be demonstrating how to easily construct great graphics using Hadley Wickham's layered grammar of graphics.  No previous programming skill is required.

This workshop will be delivered in 3 sessions:

  • Session 1: Monday, June 6, 2022 from 1:30 PM to 3:30 PM EDT

2022 COSS Machine Learning

This interactive online workshop is an introduction to the world of machine learning (ML), covering some supervised learning algorithms and when and how to use them. 

It begins by introducing the data pipeline and its processes, before moving on to statistical and visualization approaches to conduct exploratory and descriptive analytics on data in answering the question “What happened in the past?”. From there, participants will explore the art of data preparation, including data cleaning, missing values, outlier detection, and feature transformation and engineering.

Next, we will introduce predictive analytics to answer the question “What will happen?”. We will cover techniques for classifying and predicting data for the supervised learning algorithm, such as k-NN, Naïve Bayes, Decision Tree and Random Forest, and provide guidance in deciding which ones to use. Finally, participants will learn about statistical evaluation methods used in comparing the performance of predictive modelling techniques.

This workshop balances theory and practice. Participants will use practical concepts of machine learning applications to understand real-world situations.

2022 COSS Git

Version control is an important tool for tracking and safe-keeping articles and source code. Nothing is ever lost, and it is always possible to go back in time to an earlier version. It is an ideal tool for collaboration since multiple persons can work on the same project and it keeps a record of which change has been done by which person. In this course, we will look at the most popular version control software, Git, which is the basis for well-known sites such as GitHub and Gitlab. We will use Github during the course. Students will need to be familiar with basic command line to participate. (This course will be taught in English.)

This workshop will be delivered in 3 sessions:

  • Session 1: Monday, June 13, 2022 from 1:30 PM - 3:00 PM EDT

    2022 COSS Creating a Data Management Plan (DMP)

    As the brilliant Val said in Tremors, “we plan ahead, that way we don’t do anything right now.” Planning ahead is never a bad thing! Taking the time to plan out the details of managing your project’s research data is also never a bad thing, and is definitely never a waste of time.

    Data Management Plans, or DMPs, are documents that lay out the who, what, where, when, why, and how regarding your project’s research data. DMPs help researchers think through all aspects of research data management before the data is actually collected. DMPs are intended to be living documents that can be updated or modified at any point within your research project’s lifecycle. While creating a DMP may seem like a tedious, administrative task, it’s not! 

    This workshop will walk attendees through the creation of a DMP using the DMP Assistant, which is a free, Canadian-based online tool that is simple and easy to use. We’ll also talk briefly about the Tri-Agency RDM Policy and how it’s related to DMPs.
