Analysis of DNA Structure Elements
Knytl, Marek ; Burgetová, Ivana (referee) ; Martínek, Tomáš (advisor)
The aim of this master's thesis is the design and implementation of tool trackAnalysis for statistical analysis of DNA structure elements. The positions of individual elements in genome are obtained in the form of the track, and with these positions the tool performs a set of analyzes, including randomness test of track, test examining distances between track and genes, detection of clusters and overlaps. The indivudual tests results can be linked together. The results will be displayed in the form of a list, a graph or a new annotation track. An important part of this thesis is also testing the resulting tool on a set of real data.

Visualization of DNA Secondary Structures in R/Bioconductor
Jaroš, Marta ; Bendl, Jaroslav (referee) ; Martínek, Tomáš (advisor)
This bachelors thesis deals with the visualization techniques of the secondary structures of DNA. It summarizes and discusses some of the current methods of visualization. It explains the problem and its importance from the standpoint of molecular biology. The main aim of the work is the design of a generic algorithm for visualization of secondary structures of DNA, specifically palindromes and triplexes, and its implementation into the environment R/Bioconductor. It focuses in particular on the area of 2D graphical imaging of these secondary structures of DNA. The result of the work is 2D visualization support for R/Bioconductors software packages which provide searching of the characteristic sequence of palindromes and triplexes in DNA sequences.

Optimization of Algorithms for Triplex Detection
Hon, Jiří ; Bendl, Jaroslav (referee) ; Martínek, Tomáš (advisor)
Triplex-forming DNA sequences have been implicated as important players in several key processes, such as transcriptional regulation, DNA recombination and mutagenesis, which emphasize their importance for biology, biotechnology and medicine. This bachelor thesis optimizes recently publicated dynamic programming algorithm for identification of triplex-forming sequences on three levels of design: user interface, memory usage and computation time. On the level of user interface, the algorithm was extended with existing visualization functions and rewritten into R/Bioconductor package. Memory usage optimization and processor cache analysis in combination with computation time reduction based on current computation state analysis lead to more than three times acceleration.
