BIOLIGN was developed by Tom Hall in consultation with this lab. This is a great tool for alignment, SNP identification, and PHRAP evaluation.
BioEdit is a biological sequence alignment editor written for Windows 95/98/NT/2000/XP. An intuitive multiple document 
interface with convenient features makes alignment and manipulation of sequences relatively easy on your desktop computer. Several sequence manipulation and analysis options and links to external anaylsis programs facilitate a working environment which allows you to view and manipulate sequences with simple point-and-click operations.
