FSpeed is software for calculating Wright's coefficient of inbreeding.
NOTE: If you use a Mac or Windows 7, Vista or XP we recommend you try a much newer product: PedScope, which in addition to computing inbreeding incredibly quickly will also perform many other analyses of gentic diversity such as mean kinship and founder equivalents. It can also compute + display relationship matrices and can calculate mating (breeding) recommendations for maximizing future genetic diversity or minimizing inbreeding.
FSpeed may be downloaded free of charge by clicking here. It will compute inbreeding for populations of up to 5,000 distinct individuals to up to 10 generations of ancestors.
There is also a considerably enhanced version of this program, FSpeed Pro. This handles populations in excess of 1,000,000 individuals and has multi-processor support for calculation of inbreeding in parallel. Click here for details.
