De novo genome assembly - T.Seemann - IMB winter school 2016 - brisbane, au ...Torsten Seemann
?
This document discusses de novo genome assembly, which is the process of reconstructing long genomic sequences from many short sequencing reads without the aid of a reference genome. It is challenging due to factors like short read lengths, repetitive sequences that complicate the assembly graph, and sequencing errors. The goals of assembly are to produce contiguous sequences with high completeness and correctness by resolving overlaps between reads into consensus sequences. Metrics like N50, core gene content, and read remapping are used to assess assembly quality.
This document discusses next generation sequencing technologies. It provides details on several massively parallel sequencing platforms and describes their advantages over traditional Sanger sequencing such as higher throughput, lower costs, and ability to process millions of reads in parallel. It then outlines several applications of next generation sequencing like mutation discovery, transcriptome analysis, metagenomics, epigenetics research and discovery of non-coding RNAs.
AGRF in conjunction with EMBL Australia recently organised a workshop at Monash University Clayton. This workshop was targeted at beginners and biologists who are new to analysing Next-Gen Sequencing data. The workshop also aimed to provide users with a snapshot of bioinformatics and data analysis tips on how to begin to analyse project data. An introduction to RNA-seq data analysis was presented by AGRF Senior Bioinformatician Dr. Sonika Tyagi.

This document provides an overview of variant analysis from next-generation sequencing data. It begins with introductions to the CCA-Drylab@VUmc, TraIT, and Galaxy projects. The focus of the lecture is explained to be variant analysis from NGS data using interactive demos in Galaxy. Background is provided on Illumina sequencing technology and properties of sequencing reads. Key steps in variant analysis are outlined, including quality control and read mapping, variant calling and annotation using tools like FastQC, BWA, FreeBayes, and SnpEff. Formats for storing sequencing data and variants are also introduced, such as FASTQ, SAM/BAM, and VCF.
The transcriptome of a cell is not fixed, but is dynamic, and reflects the function or type of the cell, the cell stage or the cell's response to intrinsic and extrinsic influences, such as signaling or stress factors. Only on a single cell level, can you eliminate the biological noise that is inherent to standard gene expression analysis – providing you the insights needed for a deeper understanding of transcription dynamics. In this presentation we delve into the different steps of RNA seq starting from a single cell.
