Course of work with molecular data in R 2016

Submitted by vojta on Thu, 11/26/2015 - 18:35

R is nowadays probably the most powerful tool for statistics of all types. There are plenty of modules available for work with molecular data. Those will be introduced during the course. Previous knowledge of R is useful, but not necessary. If there is at least one participant not speaking Czech, the course will be in English.

Course of work in Linux command line not only for MetaCentrum 2016

Don’t be afraid of command line! It is friendly and powerful tool. Practically identical is command line also in Mac OS X, BSD and another UNIX-based systems, not only in Linux. Basic knowledge of Linux is not conditional. Course will be taught in Linux, but most of the point are applicable also for another UNIX systems like Mac OS X. Knowledge of Linux/UNIX is useful e.g. for working with molecular and another data. MetaCentrum is service provided by CESNET allowing access to huge computational capacity.

Phylogenetic marker development for target enrichment from transcriptome and genome skim data: the pipeline and its application in southern African Oxalis (Oxalidaceae)

Submitted by vojta on Thu, 11/26/2015 - 17:11

Phylogenetics benefits from using a large number of putatively independent nuclear loci and their combination with other sources of information, such as the plastid and mitochondrial genomes. To facilitate the selection of orthologous low-copy nuclear (LCN) loci for phylogenetics in non-model organisms, we created an automated and interactive script to select hundreds of LCN loci by a comparison between transcriptome and genome skim data. We used our script to obtain LCN genes for southern African Oxalis (Oxalidaceae), a speciose plant lineage in the Greater Cape Floristic Region.

Structure, R and Linux

Structure is very popular software for revealing population structure. Here I describe easy workflow how to run independent runs of Structure in parallel to speed up whole process using statistical software R and how to facilitate use of CLUMPP and distruct with easy BASH scripts.

Arlequin and R under Linux

Arlequin is very popular tool for population genetics and in recent version (3.5) it has version running on Linux (arlecore, only computational core without GUI) as well as possibility to parse output using R statistical language. Those two features are described only briefly in official manual. I faced some issues when running Arlequin on Linux and parsing output using R. I'm describing here my solutions in case someone else would hava similar needs and problems.

Bachelor thesis

Submitted by vojta on Wed, 05/30/2007 - 18:42

In my bachelor thesis I present temporal pieces of knowledge on phytogeography, and especially molecular phylogeography of water clonal plants and possibilities of their dispersion. Plenty of questions about history, dispersal, relationship and population structure we can not answer without molecular technologies at all. Another very important components influencing dispersal of plants and animals are their ecology and physiology.
