Abstract

U ovom radu implementiran je alat za produljivanje i povezivanje sastavljenih slijedova u programskom jeziku C++. Alat je nazvan Ezra i potencijalno bi se mogao koristiti za produljivanje i povezivanje u alatu za de novo sastavljanje Rala. Metode produljivanja i povezivanja bi se trebale izvršavati iterativno, ponavljajući proces sve dok ima valjanih produljenja i povezivanja.

Alat je testiran na umjetno generiranim slijedovima napravljenih nasumičnim rezanjem genoma e. coli i na rascjepanim... More slijedovima sastavljenim alatom Rala nad Pacbio bakterijskim podatkovnim skupovima. Rezultati testiranja pokazuju da je ova metoda valjana za povezivanje slijedova sastavljenih Ralom.

Abstract (english)

In this thesis, a tool for contig extension and gap closing was implemented in C++. The tool is named Ezra and could be used for extension and bridging by de novo assembler Rala. The extension and bridging methods are meant to be run in iterations, repeating the process while it produces valid extensions and bridges.

The tool was tested on artificial fragments made by randomly cutting e. coli genome and on fragmented assembly produced by Rala on Pacbio bacterial datasets.
The results show... More that this method is valid for reducing the number of contigs produced by Rala.
