Authority: plantgdb.org - This service receives as input a DNA sequence, an integer parameter indicating the maximum number of acceptable mismatches, the length value representing the minimum match length and arabidopsis index to search (Valid values are: ATexon and ATgene). Using Vmatch, a versatile software tool for efficiently solving large scale sequence matching tasks (http://www.vmatch.de/), the sequence is "matched" against the selected arabidopsis index and returns the list of "matches" (i.e. locations) in BasicGFFSequenceFeature objects. Seed length is set to 8. Important note: results limited to MAX_RESULTS (currently set to 750)
