Bioinformatics@HSL: BBT Workshop Descriptions

Descriptions of Basic Bioinformatics Tools Workshops

The Basic Bioinformatics Tools Forum series provides seminar and hands-on computer workshops on bioinformatics tools and resources to faculty, staff and students of UNC-Chapel Hill.  Class sessions are held at the Health Sciences Library in the Biogen-Idec Classroom (307; 3rd floor). For some classes, registrants have the option to attend online via Blackboard Collaborate.

Below are descriptions of workshops that have been regularly offered in past semesters.


UNIX for Biologists, Part 1: Introduction    Register

Time:  Thursday, 2/25/2016, 1:30pm - 3:30pm

Instructor: Hemant Kelkar, Ph.D., UNC Center for Bioinformatics
Location: HSL 307

The ability to operate in a command line environment is becoming increasingly valuable in the genomics era. This workshop and the subsequent "UNIX for Biologists, Part 2: Killdevil" workshop are designed for experimental biologists who want to familiarize themselves with UNIX. This workshop will provide a very basic introduction to the UNIX operating system. Participants will learn how to login (software required/procedure) and interact with a UNIX server. We will cover basic UNIX system commands for interacting with the server and navigating the file system. We will learn about UNIX directory structure organization and file permissions.

Account Requirement: You will need an account on the “Killdevil” Linux cluster managed by ITS-Research Computing. Instructions for requesting a “Killdevil” account are available at this link: http://help.unc.edu/help/getting-started-on-killdevil/#P41_2630. Please submit your account request at least 3 days before class. It generally takes 24-48 hours for account creation.

Prerequisites: No prior knowledge of UNIX is required. NOTE: For those unfamiliar with UNIX and Killdevil/UNC computer cluster usage, this class and UNIX for Biologists, Part 2: Killdevil (from this series or prior offerings) are prerequisites for the next generation sequencing classes that follows them in the BBT workshop series: "Introduction to Next Generation Sequencing Data and Quality Control" AND "Alignment of Next Generation Sequencing Data: Background and Practical Considerations."


UNIX for Biologists, Part 2: Killdevil    Register

Time:  Wednesday, 3/2/2016, 1:00pm - 3:00pm

Instructor: Hemant Kelkar, Ph.D., UNC Center for Bioinformatics
Location: HSL 307

The ability to operate in a command line environment is becoming increasingly valuable in the genomics era. This workshop and the earlier "UNIX for Biologists, Part 1: Introduction" workshop are designed for experimental biologists who want to familiarize themselves with UNIX. This workshop will introduce UNC resources available to bioscience researchers and will focus primarily on resources on the "Killdevil" compute cluster operated by UNC ITS-Research Computing. After a quick recap of basic file/folder operations used in a UNIX environment, we will cover how to move files between the server and a local computer. We will introduce the “Killdevil” compute cluster and the software used for managing jobs on the cluster. Finally, participants will learn to use two basic bioinformatics tools (NCBI BLAST and UCSC BLAT) on the command line on the Killdevil cluster.

Account Requirement: You will need an account on the “Killdevil” Linux cluster managed by ITS-Research Computing. Instructions for requesting a “Killdevil” account are available at this link: http://help.unc.edu/help/getting-started-on-killdevil/#P41_2630. Please submit your account request at least 3 days before class. It generally takes 24-48 hours for account creation.

Prerequisites: It would be very helpful to attend UNIX for Biologists, Part 1: Introduction, if you are not familiar with UNIX. If you are somewhat familiar with UNIX then you could potentially skip attending Part 1.  NOTE: For those unfamiliar with UNIX and Killdevil/UNC computer cluster usage, this class and UNIX for Biologists, Part 1: Introduction (from this series or prior offerings) are prerequisites for the next generation sequencing classes that follows them in the BBT workshop series: "Introduction to Next Generation Sequencing Data and Quality Control" AND "Alignment of Next Generation Sequencing Data: Background and Practical Considerations."


Introduction to Next Generation Sequencing Data and Quality Control    Register

Time:  Monday, 3/7/2016, 1:00pm - 3:00pm

Instructor: Hemant Kelkar, Ph.D., UNC Center for Bioinformatics
Location: HSL 307

Genome wide analysis of gene expression has been a popular technique since the advent of microarrays. Next Generation Sequencing (NGS) technology was applied for this purpose early in the life cycle and has since become one of the most popular uses of NGS. We will start with a general overview of NGS technologies and consider commonly used data formats. Because of time/space constraints, we will be using a small subset of sequences (derived from a real dataset). I will introduce FastQC which is a popular application used for quality control (QC) of NGS data. We will then take a look at examples of results from FastQC (aside from the one we will run on our test data). This will be followed by an overview of data scanning/trimming programs. These programs look for contaminating sequences (e.g. adapters) and can also trim data based on various other criteria.

Account Requirement: You will need an account on the “Killdevil” Linux cluster managed by ITS-Research Computing. Instructions for requesting a “Killdevil” account are available at this link: http://help.unc.edu/help/getting-started-on-killdevil/#P41_2630. Please submit your account request at least 3 days before class. It generally takes 24-48 hours for account creation.

Prerequisites: For those unfamiliar with UNIX and Killdevil/UNC computer cluster usage, UNIX for Biologists, Part 1 and UNIX for Biologists, Part 2 (from this series or prior offerings) are prerequisites for this class.


Alignment of Next Generation Sequencing Data: Background and Practical Considerations   Register

Time:  Monday, 3/21/2016,  3:30pm - 5:30pm

Instructor: Tristan De Buysscher, Bioinformatics Scientist
Location: HSL 307

Aligning short read sequencing data to a reference genome can be a computationally difficult problem. This class will discuss some of the issues and possible approaches to this problem. We will focus on the Burrows-Wheeler Transform class of tools (BWA, Bowtie/Tophat) with practical applications.

Account Requirement: You will need an account on the “Killdevil” Linux cluster managed by ITS-Research Computing. Instructions for requesting a “Killdevil” account are available at this link: http://help.unc.edu/help/getting-started-on-killdevil/#P41_2630. Please submit your account request at least 3 days before class. It generally takes 24-48 hours for account creation.

Differential Expression Analysis of RNAseq Data   Register

Time:  Monday, 3/28/2016,  3:30pm - 5:30pm

Instructor: Tristan De Buysscher, Bioinformatics Scientist
Location: HSL 307

RNAseq provides a snapshot of the transcription state of the cells from which RNA was harvested. One of the most common applications of this sequencing data is to look at changes in the transcriptome state between two or more conditions the cells were exposed to. We will discuss the various considerations in analyzing RNAseq data and run through a practical example using DESeq2."

Browsing Genes and Genomes with Ensembl and Ensembl Genomes (A full day workshop)   

Time: Not currently scheduled

Instructor: Denise Carvalho-Silva, PhD, EMBL-EBI
Location: HSL 307

The Ensembl and Ensembl Genomes projects provide a comprehensive and integrated source of annotation of vertebrate and non-vertebrate genome sequences, respectively. The browser workshop will include presentation and demonstration, and provide participants an opportunity to gain hands-on experience in the use of Ensembl genome browsers.

Depending on the preferences of the participants, more or less emphasis can be allocated to the Ensembl browser (vertebrates) and to the Ensembl Genomes browser (non-vertebrates). Preferences will be determined through a pre-course survey of registrants. The Ensembl browser workshops typically consist of the first three "core" modules below, plus two other modules from the list below the Core Modules. The additional two modules will be determined by a pre-course survey that will be sent to workshop registrants to identify their interests:

Core modules:

  • Introduction to Ensembl: origin, goals, gene and transcript annotation, data organization and different access points (e.g. browser, BioMart, FTP site, APIs)
  • Website live demo: guided tour of the most important pages of the Ensembl website focusing on the Location tab, Gene tab, Transcript tab, and Variation tab
  • BioMart: retrieving datasets using the web tool BioMart (no programming skills required)

Two modules to be selected from list below based on a pre-course survey of registrants:

  • Variation: short scale variation (SNPs, indels), large scale variation, (CNVs, deletions, etc), phenotype and population genetics data, VEP (Variant Effect Predictor)
  • Comparative genomics: gene trees (protein-coding and non-coding genes), orthologues, protein families, whole genome alignments and synteny
  • Regulation: ENCODE data hub, and annotation of regulatory elements based on ChIP-Seq, DNase1-Seq, FAIRE-Seq, and TFBS

Prerequisites: The only prerequisite for this workshop is general knowledge of molecular biology and genomics and a familiarity with web browsers.
