CodonCode Corporation offers Windows and Mac OS X versions of Phrap and Phred, Phil Green's programs for sequence assembly, and quality base calling. The programs Phrap, and Phred are the leading programs for base calling and sequence assembly.

Consed/Autofinish is a tool for viewing, editing, and finishing sequence assemblies created with phrap. Finishing capabilities include allowing the user to pick primers and templates, suggesting additional sequencing reactions to perform, and facilitating checking the accuracy of the assembly using digest and forward/reverse pair information.

Phrap is a widely used program for DNA sequence assembly. It is part of the Phred -Phrap- Consed package. Phrap was originally developed by Prof. Phil Green for the assembly of cosmids in large-scale cosmid shotgun sequencing within the Human Genome Project.

PHRAP uses PHRED's quality scores to determine highly accurate consensus sequences. PHRAP examines all individual sequences at a given position, and generally uses the highest quality sequence to build the consensus - similar to the way scientists would correct consensus sequences during "contig editing".

Phrap and Phred for Windows Fast sequence assembly on your desktop. CodonCode Corporation offers Windows versions of Phrap and Phred, Phil Green's programs for fast sequence assembly and better base calling.

Phrap ("phragment assembly program", or "phil's revised assembly program"), Phrap是由华盛顿大学分子生物技术学院的Phil Green和Brent Ewing开发的phred\phrap软件包的一部分，主要用于shotgun序列的组装。

2017年9月4日 · Blast（Basic Local Alignment Search Tool）用于快速查找序列相似性，而Phrap则是一款用于组装短序列的工具，它能够处理从测序实验中得到的碎片数据，进而拼接成连续的序列。 构建这个系统首先需要安装Linux操作...

Phrap is designed to be able to use all of each read sequence in the assembly, not just the trimmed (highest quality) part, so the full sequence of each read should be provided when available. If phred-generated qualities are not available however then the default quality parameter -default_qual should be set appropriately (section IV).
