LongTrace DNA Sequencing

What is LongTrace?

LongTrace is a DNA sequencing trace re-processing software system that can reduce the errors rate and improve the read length of ABI sequencing traces by up to 30%. LongTrace can be used with any trace collected on an ABI 3730, 3730xl, 3100 or 3130 DNA sequencer.


The KB v1.2 and LongTrace derived base and quality calls from a ABI3130xl 50cm trace. A. The original KB base called before LongTrace processing. B. The same trace after LongTrace processing. Note that the trace region shown is from base 1260 to 1285.

LongTrace has been superseded by our PeakTrace software.
