The success of genomic sequencing is impossible without the development of information technologies and mathematical methods for data processing to establish various features in the analyzed objects (nucleic acids) and trends in their changes. The volume of experimental data in the research of the genome has grown significantly, and new methods and algorithms are required for their processing. The primary stage of processing the data of devices for genomic parallel sequencing is the evaluation of the parameters of images obtained from video cameras in the form of electrical signals. The next stage of processing is the construction of a sequence of nucleotides according to algorithms that depend on the principle of operation of the device for sequencing nucleic acids. When performing this stage, algorithms for evaluating quality indicators for all individual readings (reads) are important. One of the ways to assess quality is to use algorithms based on the k-measure analysis methodology. The calculation of the number of occurrences of k-measures during the experiment on the parallel sequencing system makes it possible to assess the reliability of the analysis. In this article, algorithms for processing genetic analyzer data are considered. Keywords: sequencing, nucleic acid, data processing, image processing.
НОВАЯ МЕТОДИКА ОБРАБОТКИ ФЛУОРЕСЦЕНТНОГО ОТКЛИКА ПЛАВЛЕНИЯ ДНК В статье предложена усовершенствованная модель флуоресцентного отклика плавления ДНК. Модель основывается на степеннóм полиноме 3-го порядка (СП). На основе модели разработана методика обработки флуоресцентного отклика плавления ДНК, основным результатом применения которой является определение температуры плавления ДНК T m. Новая методика целенаправленно позволяет сокращать время анализа за счет увеличения дискрета измерения температуры при одновременном сужении ее диапазона. Приведены доказательства адекватности модели на основе СП. Выполнено сравнение результатов применения разработанной и известной методик на основе сигмоидальной функции (СФ) при обработке реальных данных. Показана возможность использования методики для определения неравномерности распределения температуры держателя пробирок амплификатора в режиме плавления.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
