RESUMO
MOTIVATION: To produce an open and extensible file format for DNA trace data which produces compact files suitable for large-scale storage and efficient use of internet bandwidth. RESULTS: We have created an extensible format named ZTR. For a set of data taken from an ABI-3700 the ZTR format produces trace files which require 61.6% of the disk space used by gzipped SCFv3, and which can be written and read at greater speed. The compression algorithms used for the trace amplitudes are used within the National Center for Biotechnology Information (NCBI) trace archive. lmb.cam.ac.uk/pub/staden/io_lib/test_data.

Trev is a DNA trace editor and viewer, which is available free for UNIX and Microsoft Windows platforms. It can read all the commonly used file formats, including the new, compact ZTR files.
