RNA-seq03:21

RNA-seq

9.8K
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...

Introduction to R01:11

Introduction to R

226
R is a powerful software environment for statistical computing and graphics. Originating as an implementation of the S language, developed at Bell Laboratories, R has evolved into a robust, open-source statistical software favored by statisticians and data scientists worldwide. Its comprehensive suite includes data manipulation, calculation, and graphical display capabilities, making it versatile for data analysis and visualization. Its programming language is at the core of R's...

RACE - Rapid Amplification of cDNA Ends

6.3K
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

Ribosome Profiling02:24

Ribosome Profiling

3.5K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • The rapid increase in sequencing data necessitates efficient tools for managing and analyzing summary statistics.
  • Evaluating sequencing data quality and characteristics is crucial for large-scale genome projects like the Vertebrate Genomes Project (VGP).

Purpose of the Study:

  • To develop a standalone tool, rdeval, for rapid computation and dynamic display of sequencing read metrics.
  • To address the community need for efficient sequencing data evaluation and storage.

Main Methods:

  • Rdeval computes sequencing read metrics and can store them in compressed 'sketches' for efficient recall.
  • The tool supports conversion between various file formats (e.g., FASTA, BAM, CRAM) for optimized compression and access.
  • Rdeval generates detailed visual reports with exportable data analytics.

Main Results:

  • Rdeval provides significant data compression gains through read sketches.
  • BAM format offers a good balance between compression and access speed, while CRAM provides maximum compression.
  • Analysis of human and VGP data demonstrated rdeval's utility, revealing improvements in long-read sequencing quality and assembly benefits from increased coverage.

Conclusions:

  • Rdeval is an efficient, standalone tool for evaluating sequencing read metrics, crucial for large-scale genomics.
