ElimDupes: Duplicate Sequence Removal

Purpose: Given an alignment or set of unaligned nucleotide or protein sequences, this tool compares the sequences and eliminates any duplicates or very similar suquences, thus producing a set of unique sequences.

Details: By default, the program removes all non-letter characters from the sequences, converts all letters to uppercase, and considers as a "duplicate" any sequence that is a subsequence of a longer sequence (e.g., the sequence ATG is a duplicate of the sequence CATGCC). These three default behaviors can be modified by changing the first three options shown below. In the fourth option, you can choose to restore any gaps or non-uppercase characters that were present in the input. In the fifth option, you can descide how similar among sequences would be removed. The final option gives a means of automatically analyzing your input sequences as a series of sequence groups. The results page summarizes the duplicate and unique sequence sets and allows you to view and download the resulting unique sequences file and the duplicate sequences file.
