This is a block Pro-/Seminar for Bioinformatics students.

Overview: Single-cell studies are among the very rising topics of the last few years and will strongly shape future developments of bioinformatic methods. Applying transcriptomics to measure the dynamics of gene-expression under various conditions, on the other side, is already well-established in the scientific literature, and currently experiences another up-surge due to high-throughput single-cell sequencing. In the course of this seminar, we will cover the basics of the different single-cell RNA-seq techniques and swiftly move on to advanced bioinformatics methods that help to understand the sparse single-cell datasets. To this end, we will have a look at the diverse steps of data quality assurance and technical and / or biological bias detection methods, which are necessary to implement effective single-cell RNA analysis pipelines.

Depending on the current pandemic situation, we will try to have the meetings in presence. If it is not possible, we will do remote meetings via Microsoft Teams conferences instead of personal meetings.

* If you want to deregister from the seminar, please send the tutor an email irrespectively whether you (de)registered in HISPOS or not.

** If you would like to get feedback about your slides, e.g. to improve your presentation before the talk, send your slides to the tutor before the feedback deadline. We strongly encourage you to take this opportunity. When asking for feedback the more complete the submitted presentation the more helpful our feedback can be. Thus, try to avoid submitting half-finished slides. Feedback will be provided at least once but at most twice per participant. Also, before sending in the slides, check out our support materials (presentation guidelines, presentation guidelines checklist). You must hand-in a (digital) copy of the completed guidelines checklist at latest when performing the presentation.

Please note: Your slides will make up a substantial part of the final grade. Reading and paying attention to the provided presentation guidelines will help you to get an impression of which aspects are relevant for the evaluation. Disregarding many of the points listed in the guidelines may negatively affect your grade.
