View, edit, and convert chromatograms. Trim low quality ends automatically.

Program description

DNA Chromatogram Explorer Lite is a Windows Explorer clone dedicated to DNA sequence analysis and manipulation. You can view the chromatograms while browsing through folders using its integrated file explorer. With a single click you can trim the low quality bases at the end of your samples.

The Lite version of Chromatogram Explorer is freeware.

How to use it

Exploring your samples

Start DNA Chromatogram Explorer and navigate to your DNA sample files (chromatograms).

All chromatograms in that folder will be displayed in the right panel (see picture below). SCF and ABI (ABI, AB, AB1, AB!) chromatogram files are supported. Low quality ends are shown in dark gray color. To view non-chromatogram files (FASTA, SEQ, TXT) just double click them.

Converting your samples

Press 'Convert' or 'Convert all' and your file will be saved as SCF or FASTA (as you choose).

Automatic end trimming

With DNA Chromatogram Explorer you can automatically trim low quality ends of all chromatograms in a folder. Please see this short tutorial.
