Common desktop programs used in Bioinformatics are included in DNALinux. Using VMWare you can run Linux and Windows programs side by side. DNALinux is also a webserver. You don't have to set up an Apache web server and install CGI programs since DNALinux has them pre-installed and ready to run. With a server you can make a BLAST from your host computer. DNALinux VD is a preconfigured virtual machine (VM) with applications targeted for bioinformatics (both DNA and protein analysis). This virtual machine runs on top of the free VMWare Player. This player can run in Windows machines and since the VM works inside the player, everything you do with DNALinux VD doesn't touch the host computer so you can have two separated working environment (DNALinux and Windows together on the same computer).
