The ACE file format is a specification for storing data about genomic contigs.
The original ACE format was developed for use with Consed, a program for viewing, editing, and finishing DNA sequence assemblies.
ACE files are generated by various assembly programs, including Phrap, CAP3, Newbler, Arachne, AMOS (sequence assembly) (more specifically Minimo) and Tigr Assembler v2.
