Direct assembly of genome signals from nanopore sequencing
Karmazinová, Inna ; Maděránková, Denisa (referee) ; Sedlář, Karel (advisor)
The aim of this bachelor thesis is to search for overlaps between signals from nanopore sequencing using MinION device version R9. The theoretical part deals with methods used for genome assembly - greedy algorithm, overlap-layout-consensus (OLC) and de Bruijn graphs. Oxford Nanopore Technologies introduced the MinION device, which simplifies sequencing using the current change, which occurs while the DNA is passing through the nanopore. The error rate of the device is still high, the accuracy problem occurs during the base-calling. Using the difference signal, possibly also the dynamic time warping, it is possible to find overlaps between the individual signals. Signal analysis and genome assembly using the MinION signal could provide better accuracy.
Comparison of bacterial genomes obtained from second and third generation sequencing
Rumlerová, Tereza ; Škutková, Helena (referee) ; Nykrýnová, Markéta (advisor)
This bachelor thesis deals with sequencing technologies with a focus on the second and third generation of sequencers and platforms Illumina Miseq and Oxford Nanopore Technologies MinION. There is a description of an assembly of genomes with an example of the assembly of 6 genomes of a bacteria Klebsiella pneumoniae and a quality testing of these genomes. The final part contains a theoretical description and a practical implementation of selected methods for comparison of the assembled genomes, which come from two different sequencing platforms.
Advanced Computational Methods for Increasing the Discriminatory Power of Genotyping Methods
Nykrýnová, Markéta ; Budinská, Eva (referee) ; Hrabák,, Jaroslav (referee) ; Škutková, Helena (advisor)
Tato disertační práce je zaměřena na vytvoření nových výpočetních metod, které zvýší diskriminačních schopnost genotypizačních metod. Hlavní důraz je kladen na odlišení blízce příbuzných bakterií, které pocházejí například z jedné nemocnice či jednoho oddělení. V první části práce jsou popsány současné typizační metody a jsou představeny nové postupy pro identifikaci genetických markerů s vysokou mírou sekvenční variability, pomocí kterých lze lépe rozlišit bakteriální populaci. Navržené metody jsou založeny na výpočtu signálů entropie a analýze nenamapovaných čtení. Druhá část práce se zabývá návrhem nových metod zpracování surových dat z nanopórového sekvenování, které lze použít pro rychlou vysoce citlivou typizaci bakterií bez nutnosti převádět proudové signály na nukleotidové sekvence. Předložená práce přispívá ke zlepšení a zpřesnění rutinně používaných typizačních metod pomocí navržených bioinformatických postupů a představuje unikátní přístup využití doposud experimentální techniky nanopórového sekvenování pro rychlou genotypizaci a analýzu bakterií.
