Chromatograms

A chromatogram (sometimes also called electropherogram) is the visual representation of a DNA sample produced by a sequencing machine (like Applied Biosystems ABI PRISM 7700 Sequence Detection System). DNA Baser supports SCF and ABI (ABI, AB, AB!, AB1) chromatogram files.

Fig. 1 - Example of chromatogram files. The green bars indicate this chromatogram has a very high quality.

To open a chromatogram file just double click on it in Project Manager.

Chromatogram files can be easily converted to FASTA or SEQ with tools like DNA Baser, Chromatogram Explorer,  Multi-FASTA to FASTA converter, FASTA to Multi-FASTA converter, ABI to FASTA converter. Please see the Download page for details.
