       HMMER is designed to detect remote homologs as sensitively as possible, relying on the strength of its underlying probability models. In the past, this strength came at significant computational expense, but as of the new HMMER3 project, HMMER is now essentially as fast as BLAST.
       HMMER can be downloaded and installed as a command line tool on your own hardware, and now it is also more widely accessible to the scientific community via new search servers at the European Bioinformatics Institute.

       This Doulos SIL font is essentially the same design as the SIL Doulos font first released by SIL in 1992. The design has been changed from the original in that it has been scaled down to be a better match with contemporary digital fonts, such as Times New Roman®. This current release is a regular typeface, with no bold or italic version available or planned. It is intended for use alongside other Times-like fonts where a range of styles (italic, bold) are not needed. Therefore, just one font is included in the Doulos SIL release: Doulos SIL Regular.

       The Embedded Linux* Library (ELL) provides core, low-level functionality for system daemons. It typically has no dependencies other than the Linux kernel, C standard library, and libdl (for dynamic linking). While ELL is designed to be efficient and compact enough for use on embedded Linux platforms, it is not limited to resource-constrained systems.
