A request was made for "DNA - Strider like" packages for the PC (DOS) world.
You may want to check out Seqaid which can be found at ftp.bio.indiana.edu,
ftp.bchs.uh.edu and nic.funet.fi (Kudos to Don, Dan and Rob for maintaining tho
se sites). You may also want to take a look at Fsap, which can be found at
ccu.umanitoba.ca (Kudos to Brian).
Best of luck,
