Workshop 2022 Programme

PART I.  BASIC TRAINING (online, performed individually any time before May 24)

It is strongly recommended that all inexperienced RepeatExplorer users go through the tutorials listed below and perform all the hands-on tasks associated with them. The tutorials cover everything from setting up the user account on a public RepeatExplorer server, preparing input sequence data, and running four basic protocols that demonstrate various uses of RE, to downloading the data and then analysing it. These topics are not covered in the hands-on training sessions of the workshop, with the exception of using some of their output data for specific training and troubleshooting.

Online tutorials:

  • Galaxy environment and RepeatExplorer server [VIDEO tutorial]
  • Protocol 1: Repeat analysis in a single species [VIDEO tutorial]
  • Protocol 2: Comparative repeat analysis in multiple species [VIDEO tutorial]
  • Structure of the RepeatExplorer output files [VIDEO tutorial]
  • Protocols 1 + 2: evaluation and interpretation of the results, downstream analysis, data visualization tools [VIDEO tutorial]
  • Protocol 3: TAREAN analysis of satDNA and FISH probe design [VIDEO tutorial]
  • Protocol 4: Identification of centromeric repeats using ChIP-seq analysis [VIDEO tutorial]

Please see the information below each video tutorial for links to additional resources. The protocols are also fully described in the publication:
Novak, P., Neumann, P., Macas, J. (2020) – Global analysis of repetitive DNA from unassembled sequence reads using RepeatExplorer2Nature Protocols 15:3745–3776.
