Abstract

Mjerenje relativnih količina RNA transkripata u uzorku može biti vrlo važno za
različite primjene u biologiji i medicini. Sekvenciranje sljedeće generacije postaje
primarno korištena tehnologija za omogućavanje takvih analiza pružanjem osnovnih
podataka o uzorku. U ovome radu, prezentirao sam statistički model procjene količine
RNA koji koristi očitanja sekvenciranja sljedeće generacije s ciljem pronalaženja optimalnih vrijednosti relativnih količina. isomorph, programska implementacija ovog... More modela je opisana u radu. isomorph pokušava pronaći maksimum funkcije izglednosti po parametrima koji
predstavljaju relativne nivoe prisutnosti transkripata u uzorku. Testiranje je pokazalo
da za očitanja bez parova, isomorph ima zadovoljavajuću točnost, dok za očitanja u
parovima pokazuje potrebu za dodatnim poboljšanjima performansi. Dostupan je na

Abstract (english)

Providing a measure of abundances of different RNA transcripts in a sample can
be very important in many different biological or medical studies. Next-generation
sequencing is becoming a technology of choice for providing fundamental data for
such analyses. In this work, I have presented an RNA abundance estimation model
that uses next-generation RNA-Seq reads to estimate optimal relative transcript abun-
dance values. isomorph, a software implementation of this method is presented
and... More explained. isomorph tries to maximize a likelihood function with regards to
isoform abundance levels to provide an optimal estimate of relative transcript abun-
dances in a sample. Testing has shown that for single-end reads, isomorph performs
well, while paired-end data performance should be more improved. It is available at
