RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Sanger Sequencing

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

Background:

High-throughput sequencing technologies generate long, high-accuracy reads.
Existing tools excel at read alignment for genome assembly.
Analyzing specific features within these reads, such as mutations or barcodes, remains challenging.

Purpose of the Study:

To introduce alignparse, a Python package designed for parsing complex features from long sequencing reads.
To provide a flexible tool for extracting and analyzing user-defined genetic elements from sequencing data.

Main Methods:

Utilizes Genbank Flat File format for defining target sequences and features.
Aligns sequencing reads to specified targets.
Filters alignments based on the presence and identity of user-defined features.
Parses out sequences, mutations, and accuracy for specified features.

Main Results:

alignparse successfully extracts complex feature sets from long sequencing reads.
The package allows for customizable feature identification and analysis.
Demonstrates flexibility in handling various features like mutations, unique molecular identifiers, and barcodes.

Conclusions:

alignparse addresses the need for a specialized tool to analyze complex features in large-scale sequencing datasets.
The package enhances the utility of long-read sequencing for applications beyond genome assembly.
