ACT is a DNA sequence comparison viewer based on Artemis. The name ACT stands for Artemis Comparison Tool. ACT is written in Java, reads EMBL or GENBANK format sequences and feature tables, and can work on sequences of any size.
ACT understands several different comparison file formats. See the section called Running a Comparison in Chapter 2 for details. Note that ACT is a comparison viewer only. The comparison information itself must be generated externally. See the section called Running a Comparison in Chapter 2 for more details.
