equicktandem and etandem in EMBOSS

equicktandem - Scans for potential tandem repeats in a nucleotide sequence. 

equicktandem scans a sequence for potential tandem repeats up to a
specified size.  The results can be used to run etandem on the candidate
repeat lengths to identify genuine tandem repeats.  Z

etandem - Looks for tandem repeats in a nucleotide sequence

etandem looks for tandem repeats in a sequence.  It is normally used
after equicktandem has been run to identify potential repeat sizes.
