全基因组敲除研究、非编码删除扫描和其他大规模研究需要一个简单且轻量级的框架,该框架可以快速发现并评分数千个针对任意 DNA 序列的候选 CRISPR 指南。虽然存在多种 CRISPR Web 应用程序,但仍需要一种高通量工具来快速发现和处理数十万个 CRISPR 靶标。在这里,我们介绍 FlashFry,这是一种快速、灵活的命令行工具,用于表征大量 CRISPR 靶序列。借助 FlashFry,用户可以指定假定的脱靶的不匹配数量,对发现的站点进行丰富的注释,并使用常用的在靶和脱靶评分指标来标记潜在的指南。 FlashFry 的运行速度与常用的全基因组序列比对器相当,并且输出以易于操作的文本文件形式提供。 FlashFry 是一种快速、方便的命令行工具,用于发现大型 DNA 序列中的 CRISPR 靶点并对其进行评分。
Genome-wide knockout studies, noncoding deletion scans, and other large-scale studies require a simple and lightweight framework that can quickly discover and score thousands of candidate CRISPR guides targeting an arbitrary DNA sequence. While several CRISPR web applications exist, there is a need for a high-throughput tool to rapidly discover and process hundreds of thousands of CRISPR targets. Here, we introduce FlashFry, a fast and flexible command-line tool for characterizing large numbers of CRISPR target sequences. With FlashFry, users can specify an unconstrained number of mismatches to putative off-targets, richly annotate discovered sites, and tag potential guides with commonly used on-target and off-target scoring metrics. FlashFry runs at speeds comparable to commonly used genome-wide sequence aligners, and output is provided as an easy-to-manipulate text file. FlashFry is a fast and convenient command-line tool to discover and score CRISPR targets within large DNA sequences.
