BLASTcirc

 

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.

The current version of BLASTcirc provides circRNA search for ten plants (Arabidopsis, rice, maize, soybean, cotton, oilseed rape, tomato, cucumber, Chinese cabbage and grape). Read more about BLASTcirc at here.
