FSpeed Pro is software for calculating Wright's coefficient of inbreeding for large populations and/or to considerable depth of ancestors.
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.
Incredibly fast - see below
Population input from text file (comma or tab separated)
Up to 3,000,000 distinct individuals within a population
Computes inbreeding as far back as 60 generations
Detects self-parenting errors (circularities)
Tabulates various statistics along with the inbreeding coefficient: #ancestors, #common ancestors, etc.
Results may be sorted in various ways
Results may be saved (to text file).
Has multi-processor support: FSpeed Pro will use all available processors to compute the results - i.e. F is computed in parallel using all CPU resources available.
NOTE: There is a slimmed down, free, version of this program available that handles populations of up to 5,000 individuals to a depth of up to 10 generations. Click here for details.
Very. E.g. we set FSpeed Pro to calculate F to 16 generations for every dog in a database of Dalmatians - some 72,500 dogs - and it took just 2 minutes 44 seconds for the entire database. This was a database of most UK registered Dalmatians dating back over 100 years, a relatively closed population with extensive inbreeding typical of a pedigreed population. The machine used was a dual processor Athlon MP1800 (1.4Ghz) system with 1Gb RAM - by no means top of the range by todays standards.
Windows 98 or later. For multi-processor support you need a multi-processor capable version of Windows (i.e. Windows NT, 2000, XP, Vista or successor)
Pentium II or later CPU (includes Pentium III, Pentium IV, Athlon, Celeron etc.)
256Mb RAM minimum.

The program is licensed for use on a single computer. Discounts are available for multiple purchases. Site licences also available. Contact us for details.
Our breeders pedigree and record keeping program, Breeders Assistant Pedigree Software, also includes fast calculation of Wright's inbreeding coefficient - along with many other features.
