CRISPR Finder flow chart. (Step 1) Browsing the maximal repeats to get possible CRISPR localizations using the Vmatch program. (Step 2) Consensus DR selection according to candidate occurrences and a score computation: the score privileges internal mismatches between direct repeats of a cluster rather than boundary mismatches. (Step 3) DR and spacers size check. (Step 4) Tandem repeats elimination using ClustalW for aligning spacers.
