Data from: ExcaliBAR: a simple and fast software utility to calculate intra- and interspecific distances from DNA barcodes

In the context of DNA Barcoding, sequences of standard marker genes for thousands and potentially millions of individuals and species are becoming available, requiring ever more efficient bioinformatic environments and software algorithms for analysis. We here present ExcaliBAR (Extraction, Calculation, Barcoding), a user-friendly software utility to facilitate one important initial step in DNA barcoding analyses, namely the determination of the barcoding gap between pairwise genetic distances among and within species, based on original distance matrices computed by MEGA software. In addition, the software is able to rename sequences downloaded via the standard user interfaces of public databases such as GenBank, without the need of developing and applying specific scripts for this purpose.在DNA条形码（DNA Barcoding）研究背景下，数千乃至数百万个体与物种的标准标记基因序列正逐步公开，这对更高效的生物信息学分析环境与软件算法提出了更高要求。我们在此推出ExcaliBAR（全称：提取、计算、条形码，Extraction, Calculation, Barcoding）——一款用户友好型软件工具，可助力DNA条形码分析中的关键初始步骤：基于MEGA软件计算得到的原始距离矩阵，测定物种种间与种内两两遗传距离间的条形码间隙。此外，该软件还支持对通过GenBank（基因库）等公共数据库标准用户界面下载的序列进行重命名，无需为此开发或应用专用脚本。
