De Novo Genomic Analyses for Non-Model Organisms: an Evaluation of Methods Across a Multi-Species Data Set
De novo genomic analyses for non-model organisms: an evaluation of methods across a multi-species data set Sonal Singhal [email protected] Museum of Vertebrate Zoology University of California, Berkeley 3101 Valley Life Sciences Building Berkeley, California 94720-3160 Department of Integrative Biology University of California, Berkeley 1005 Valley Life Sciences Building Berkeley, California 94720-3140 June 5, 2018 Abstract High-throughput sequencing (HTS) is revolutionizing biological research by enabling sci- entists to quickly and cheaply query variation at a genomic scale. Despite the increasing ease of obtaining such data, using these data effectively still poses notable challenges, especially for those working with organisms without a high-quality reference genome. For every stage of analysis – from assembly to annotation to variant discovery – researchers have to distinguish technical artifacts from the biological realities of their data before they can make inference. In this work, I explore these challenges by generating a large de novo comparative transcriptomic dataset data for a clade of lizards and constructing a pipeline to analyze these data. Then, using a combination of novel metrics and an externally validated variant data set, I test the efficacy of my approach, identify areas of improvement, and propose ways to minimize these errors. I arXiv:1211.1737v1 [q-bio.GN] 8 Nov 2012 find that with careful data curation, HTS can be a powerful tool for generating genomic data for non-model organisms. Keywords: de novo assembly, transcriptomes, suture zones, variant discovery, annotation Running Title: De novo genomic analyses for non-model organisms 1 Introduction High-throughput sequencing (HTS) is poised to revolutionize the field of evolutionary genetics by enabling researchers to assay thousands of loci for organisms across the tree of life. -
MATCH-G Program
MATCH-G Program The MATCH-G toolset MATCH-G (Mutational Analysis Toolset Comparing wHole Genomes) Download the Toolset The toolset is prepared for use with pombe genomes and a sample genome from Sanger is included. However, it is written in such a way as to allow it to utilize any set or number of chromosomes. Simply follow the naming convention "chromosomeX.contig.embl" where X=1,2,3 etc. For use in terminal windows in Mac OSX or Unix-like environments where Perl is present by default. Toolset Description Version History 2.0 – Bug fixes related to scaling to other genomes. First version of GUI interface. 1.0 – Initial Release. Includes build, alignment, snp, copy, and gap resolution routines in original form. Please note this project in under development and will undergo significant changes. Project Description The MATCH-G toolset has been developed to facilitate the evaluation of whole genome sequencing data from yeasts. Currently, the toolset is written for pombe strains, however the toolset is easily scalable to other yeasts or other sequenced genomes. The included tools assist in the identification of SNP mutations, short (and long) insertion/deletions, and changes in gene/region copy number between a parent strain and mutant or revertant strain. Currently, the toolset is run from the command line in a unix or similar terminal and requires a few additional programs to run noted below. Installation It is suggested that a separate folder be generated for the toolset and generated files. Free disk space proportional to the original read datasets is recommended. The toolset utilizes and requires a few additional free programs: Bowtie rapid alignment software: http://bowtie-bio.sourceforge.net/index.shtml (Langmead B, Trapnell C, Pop M, Salzberg SL. -

Apply Parallel Bioinformatics Applications on Linux PC Clusters
Tunghai Science Vol. : 125−141 125 July, 2003 Apply Parallel Bioinformatics Applications on Linux PC Clusters Yu-Lun Kuo and Chao-Tung Yang* Abstract In addition to the traditional massively parallel computers, distributed workstation clusters now play an important role in scientific computing perhaps due to the advent of commodity high performance processors, low-latency/high-band width networks and powerful development tools. As we know, bioinformatics tools can speed up the analysis of large-scale sequence data, especially about sequence alignment. To fully utilize the relatively inexpensive CPU cycles available to today’s scientists, a PC cluster consists of one master node and seven slave nodes (16 processors totally), is proposed and built for bioinformatics applications. We use the mpiBLAST and HMMer on parallel computer to speed up the process for sequence alignment. The mpiBLAST software uses a message-passing library called MPI (Message Passing Interface) and the HMMer software uses a software package called PVM (Parallel Virtual Machine), respectively. The system architecture and performances of the cluster are also presented in this paper. Keywords: Parallel computing, Bioinformatics, BLAST, HMMer, PC Clusters, Speedup. 1. Introduction Extraordinary technological improvements over the past few years in areas such as microprocessors, memory, buses, networks, and software have made it possible to assemble groups of inexpensive personal computers and/or workstations into a cost effective system that functions in concert and posses tremendous processing power. Cluster computing is not new, but in company with other technical capabilities, particularly in the area of networking, this class of machines is becoming a high-performance platform for parallel and distributed applications [1, 2, 11, 12, 13, 14, 15, 16, 17]. -

Sequence Alignment/Map Format Specification
Sequence Alignment/Map Format Specification The SAM/BAM Format Specification Working Group 3 Jun 2021 The master version of this document can be found at https://github.com/samtools/hts-specs. This printing is version 53752fa from that repository, last modified on the date shown above. 1 The SAM Format Specification SAM stands for Sequence Alignment/Map format. It is a TAB-delimited text format consisting of a header section, which is optional, and an alignment section. If present, the header must be prior to the alignments. Header lines start with `@', while alignment lines do not. Each alignment line has 11 mandatory fields for essential alignment information such as mapping position, and variable number of optional fields for flexible or aligner specific information. This specification is for version 1.6 of the SAM and BAM formats. Each SAM and BAMfilemay optionally specify the version being used via the @HD VN tag. For full version history see Appendix B. Unless explicitly specified elsewhere, all fields are encoded using 7-bit US-ASCII 1 in using the POSIX / C locale. Regular expressions listed use the POSIX / IEEE Std 1003.1 extended syntax. 1.1 An example Suppose we have the following alignment with bases in lowercase clipped from the alignment. Read r001/1 and r001/2 constitute a read pair; r003 is a chimeric read; r004 represents a split alignment.

Sequence Analysis Instructions
Sequence Analysis Instructions In order to predict your drug metabolizing phenotype from your CYP2D6 gene sequence, you must determine: 1) The assembled sequence from your two opposing sequencing reactions 2) If your PCR product even represents the human CYP2D6 gene, 3) The location of your sequence within the CYP2D6 gene, 4) Whether differences between your alleles and CYP2D6*1 sequence represents sequencing errors or polymorphisms in your sequence, and 5) The effect(s) of any polymorphisms on CYP2D6 protein sequence. As you analyze your gene sequence, copy and paste your analyses and results into a text file for your final lab report. If some factor, like the quality of your sequence, prevents you from carrying out the complete analysis, your grade will not be penalized—just complete as many of the steps below as possible, and include an explanation of why you could not complete the analysis in your final report. Font appearing in bold green italics describes questions to answer and items to include in your final report. Part 1: Assembling your CYP2D6 sequence from both directions The sequencing reaction only produces 700-800 bases of good sequence. To get most of the sequence of the 1.2 Kbp PCR product, sequencing reactions were performed from both directions on the PCR product. These need to be assembled into one sequence using the overlap of the two sequences. In order to assure that it is going in the forward direction, it is best to derive the reverse complement sequence from the reverse sequencing file. Take the text file and paste it into a program like http://www.bioinformatics.org/sms/rev_comp.html. -
