BE-Analyzer

A JavaScript-based instant assessment tool for NGS data of CRISPR base edited cells.


Thanks to the improvements in the newest JavaScript engines in the most recent web browsers, the JavaScript based internal algorithm of BE-Analyzer completely runs onthe client-side so that large amounts of sequencing data do not need to be uploaded to the server.

To comfirm that the substitutions are derived from CRISPR base editors, it is recommended to compare the treated data with untreated one as a negative control.

Note that reference sequences can be adjusted according to the direction of crRNA. If your crRNA targets the opposite strand of reference sequences, they will be displayed as reverse complementary form.
