Package repositories

in use in many academic institutions, and some bioinformaticians have made their own software packages available for this distribution in the deb format.

Red Hat

Package repositories are generally specific to the distribution of Linux the bioinformatician is using. A number of Linux variants are prevalent in bioinformatics work.

Many users of bioinformatics applications have produced RPMs (Red Hat's package format) designed to work with Fedora, which you can potentially also install on

Live DVDs/CDs

Live DVDs or CDs are not an ideal way to provide bioinformatics computing, as they run from a CD/DVD drive. This means they are slower than a traditional hard disk installation and have limited ability to be configured. However, they can be suitable for providing ''ad hoc'' solutions where no other Linux access is available, and may even be used as the basis for a Linux installation.

Standard distributions with good bioinformatics support

In general, Linux distributions have a wide range of official packages available, but this does not usually include much in the way of scientific support. There are exceptions, such as those detailed below. ; Gentoo Linux

(for testing). Although a very flexible system with excellent community support, the requirement to install from source means that Gentoo systems are often slow to install, and require considerable maintenance. It is possible to reduce some of the compilation time by using a central server to generate binary packages. On the other hand, you can fine tune all to run at the highest speed utilizing the best of your processor (for example to actually use SSE and AVX and AVX2 CPU instructions). Binary-based distro's usually provide binaries using only i686 or even just i386 instruction sets. ; FreeBSD

. Users can also choose to build and install any port from source in order to enable non-portable optimizations or other build options. The build-from-source option also allows the ports system to automate installation of software with a license that does not permit redistribution. The ports collection contains over 31,000 ports, of which over 2,200 are in scientific categories, and over 240 are biology-related. New ports and updates are listed on the Fresh Ports site. ; pkgsrc The

derivatives. Like FreeBSD ports, pre-compiled binary packages are maintained for some platforms. Packages can be built from source on any platform, or if additional optimizations or options are desired. The pkgsrc collection contains over 19,000 packages, of which nearly 800 are in scientific categories, and over 60 are biology-related. ; Debian There are more than a hundred bioinformatics packages provided as part of the standard Debian installation.

Community building and support systems

Providing support and documentation should be an important part of any BioLinux project, so that scientists who are not IT specialists may quickly find answers to their specific problems. Support forums or mailing lists are also useful to disseminate knowledge within the research community. Some of these resources are linked to here.
