Figaro
From AMOS WIKI
Overview
Figaro is a software tool for identifying and removing the vector from raw DNA sequence data without prior knowledge of the vector sequence. By statistically modeling short oligonucleotide frequencies within a set of reads, Figaro is able to determine which DNA words are most likely associated with vector sequence. For a description of Figaro's algorithms please see our paper. You may download Figaro individually, or as part of the AMOS package at Sourceforge.
