The NextGENe Condensation Tool uses depth of coverage to correct sequence reads that contain instrument base calling errors and to elongate reads, while merging identical reads or maintaining read number as necessary for your project. Three methods are available for condensation—Consolidation, Elongation, and Error Correction. All three of the methods correct low frequency instrument errors by generating a consensus sequence from clustered reads. The type of data that you are analyzing—Illumina, SOLiD System, Ion Torrent, or Roche/454— determines the available methods.
