Compositionally Appropriate Analysis of Transcriptome, Metagenome, and Microbiome Datasets

Organizers:
Greg Gloor is a Professor of Biochemistry at The University of Western Ontario. He is one of the pioneers in using compositional data analysis to analyze HTS datasets. He is the maintainer of the ALDEx2 R package on Bioconductor used for differential relative abundance analysis. He has published original research, methods papers, and reviews that use compositional data analysis methods to interpret HTS datasets using transcriptome, microbiome and meta-transcriptome datasets (Bian et al.; Fernandes et al., 2013, 2014; Gloor and Reid, 2016; Gloor et al., 2016a, 2017, 2016b, 2016c; Goneau et al., 2015; Macklaim et al., 2013; McMillan et al., 2015; Wolfs et al., 2016). He has taught undergraduate and graduate courses in computational biology for almost two decades, and has won awards from both student groups and faculty-wide competitions.

Ionas Erb is a PDF and Bioinformatician at the Centre for Genomic Regulation in Barcelona. He is an active developer of tools to determine compositional association and is a contributor to the propr R package on CRAN used to explore correlation in a compositionally appropriate manner (Erb and Notredame, 2016; Erb et al., 2017; Quinn et al., 2017a).

Description:
There is increasing awareness that datasets generated by high throughput sequencing are compositional leading to both false positive and false negative inference. This workshop will show the dangers of ignoring the compositional nature of the data, and provide appropriate tools for compositional analysis at all stages of analysis. We will teach participants the toolset needed to conduct exploratory data analysis (biplots and clustering), correlation (propr) and differential relative abundance (ALDEx2) in a compositionally appropriate manner.

Learning Objectives:
1) Be able to identify when biological datasets are compositional, and understand the root problems that cause problems when interrogating compositional datasets.
2) Understand why HTS data should be analyzed in a compositionally-appropriate framework.
3) Know how to install, use and interpret the output from the basic HTS compositional toolkit that consists of compositional biplots, the propr R package and the ALDEx2 R package.
4) Have a frame of reference for more complex compositional tools such as philr and concepts such as b-association and balance dendrograms.

Audience Level:
The intended audience for this session is bioinformaticians or computational biologists who use high throughput sequencing with experimental designs that include tag sequencing (eg. 16S rRNA gene sequencing), metagenomics, transcriptomics or meta-transcriptomics.
This is not intended to be an introduction to R for bioinformaticians: attendees should be relatively proficient with R, either using RStudio, or on the command line and should have a plain text editor available. Attendees will use R markdown documents to keep track of their work, and templates will be provided for use. Attendees will be expected to have a laptop with R installed and the following packages and their dependencies: propr (CRAN), ALDEx2 (Bioconductor), omicplotR (Bioconductor), zCompositions (CRAN). Attendees are encouraged to bring their own datasets for analysis, but should be aware that only pairwise (i.e., two condition) experiments will be demonstrated.
Compositional concepts will be at an introductoryintermediate level suitable for participants of any background, but will be more intuitive to those with a grounding in probability and linear algebra.
The practical aspects will be at an intermediate level, suitable for participants with pre-exisiting competency in R.
Attendance should be capped at approximately 40 participants. 
ATTENDEES MUST BRING THEIR OWN LAPTOP.

CALL FOR SUBMISSIONS
Deadline 29 January 2018
Late Breaking Deadline 21 February 2018

NGS 2018 invites the submission of abstracts* describing either original, unpublished research or research that has been published recently in a high-impact journal.  Selection for presentation as either an oral presentation or a poster will be based on the review of extended abstracts. Authors who submit original, unpublished work selected for presentation at the conference may be invited to submit a full-length paper or extended abstract with full data for peer-review to published** in the ISCB Community Journal, ISCB NGS-BARCELONA channel. All posters will also be invited to submit in poster format to the ISCB NGS-BARCELONA channel.

The program will address a wide range of topics such as genome assembly, variant characterization and analysis, gene expression, population history, and disease.  Sizeable space is dedicated to submission-based presentations from the topics listed below.

Topics include:

• State of the art technologies, and technologies under development
• Novel software and algorithms
• Reproducibility
• Novel applications of NGS technologies in genomics and biology
• Genomic and transcriptomic analyses, including RNA analysis, transcription factor binding sites profiling, histone modifications, nucleosome positioning, copy number variation, genotyping, RNA structure, dynamics of transcription and translation, etc.
• Research breakthroughs based on exhaustive applications of NGS.
• Clinical and translational applications
• Applications to agriculture and biotechnology
• Societal and economic implications: forensic law, sociology research, history, etc.
• Economical impacts

Plan to submit your research to this engaging conference!
*    Abstract text limited to 300 words
**    Authors are responsible for publishing fees. ISCB members receive a 20% discount.
