BLASTcirc is a tool for finding whether or not a query sequence is a circular RNA (circRNA) by searching against a genome or transcriptome. BLASTcirc can determine whether query sequences contain back-splicing sites based on basic local alignment, provides the statistical significance of the potential circRNAs using a global alignment algorithm, and optimizes a composite score (score A) for each alignment by taking into account all potential genomic locations of back-splicing sites...
