I'm looking for a simple command-line program that will automatically assemble pairs of fairly long Sanger chromatographs. The assembly software solutions I've found are either extreme overkill for what I want to do (optimized for assembling millions of short next-gen reads) or GUI-only (Geneious or Sequencher). Phred/phrap would be the obvious answer, but it's non-free and closed-source and also pretty ancient. I'm not even looking to create publishable sequences -- just trying to use this as a QC step for DNA barcodes. Thanks!
