Course of work with molecular data in R 2022

Submitted by vojta on Thu, 11/11/2021 - 12:55

R is nowadays probably the most powerful tool for calculations of all kinds. There are plenty of modules available for work with molecular data. Their representative selection will be introduced during the course.

The course contains theory of used methods, tutorials with test data, tasks for individual work of participants, and more. The aim is to teach students how to analyze molecular data in R programming language, introduce available packages for their analysis and practical trying out to work with own or provided data.

Previous knowledge of R is useful, but not necessary. At least basic knowledge of molecular biology is required, previous knowledge about any methods how to analyse DNA data is recommended. The course is aiming primarily to Master and Ph.D. students, for Bachelor students only if they are highly advanced.

The course will be taught 5 days, while 4 days are for teaching and last day is for exams and individual consultations. Course participants can stay this last day (which is recommended), but it is not conditional.

If there is at least one participant not speaking Czech, the course will be in English.

Information are continuously updated in SIS. Schedules are also in SIS. The course will be taught in lecture hall OŽP B12 (1st mezzanine, Benátská 2, Prague 2) from January 31 to February 4, 2022, from 9:00 AM to 4-5:00 PM (with enough breaks). I'd be glad if participants could fill a short questioner which will help me with preparation of the course and communication with participants.

The course will be combination of shorter talks followed by independent work of students, and room for questions and consultations, etc.

Depending on epidemiological situation the course can be in hybrid mode (not only in full attendance) or fully on-line only. Details will be updated according to the situation prior the course.
