Description

During the last decade, environmental sequencing has become a standard tool to monitor biodiversity for both micro- and macro-organisms. Following the development of high-throughput sequencing, a myriad of tools have been developed to efficiently process the ever increasing amount of sequence data produced. Target amplification of environmental DNA, also known as metabarcoding, is the most common and up-to-date technique used to assess the diversity of target organisms in the environment and is applied to a wide range of organisms, from bacteria, fungi and protists, to plant and insects.

During the courses, the participants will learn how to use bash and R scripting language for efficient processing of meta barcoding and biodiversity datasets. No previous knowledge of bash is needed, but basic R knowledge is requested.

Program

The course will be organised on two days:

Day 1 – From raw reads to OTU table:
 09:00 – 11:00:  general introduction onto the applications of metabarcoding to scientific questions in ecology and to the main bioinformatics analyses techniques.
 11:00 – 11:20:  tea & coffee break
 11:20 – 13:00:  introduction to UNIX environment and bash scripting applied to large sequence file manipulation
 13:00 – 14:00:  lunch break
 14:00 – 16:30:  Illumina MiSeq raw reads quality trimming and pair-end merging – hands-on parallel computation
 16:30 – 16:50:  tea & coffee break
 16:50 – 18:00:  ASV/OTU clustering and taxonomic assignment

Day 2 – Alpha and Beta diversity:
 09:00 – 11:00:  introduction to the R software and to the vegan, dplyr and ggplot packages
 11:00 – 11:20:  tea & coffee break
 11:20 – 13:00:  alpha diversity: normalization, measure and statistical tests
 13:00 – 14:00:  lunch break
 14:00 – 16:30:  taxonomic composition: publication ready figures and statistical tests
 16:30 – 16:50:  tea & coffee break
 16:50 – 18:00:  beta diversity: testing effect of experimental factors and parameters on community composition
 18:00 – 18:15:  feedback and farewell

Evaluation

Full attendance and active participation.

Make sure to sign the attendance list each and every day!

Information

No previous knowledge of bash is needed, but basic R knowledge is requested. Ideally, a previous attendance of an introductory course to R is recommended.

The course will take place in a computer room of the University of Neuchâtel. The students will use the provided computers (one computer per student with every software needed for the course already installed) and example datasets to realize all the bioinformatic and statistic practical duties.

The participants could bring there own computer, but should have all software already installed (A list with links of sotware to be installed can be provided upon request). No support to installation and configuration of software on personal computers will be provided.

If a participant wants to analyze his/her own metabarcoding dataset, he/she should contact the course instructor beforehand.
