The current version of IBDfinder is listed on the top row of the table below. The documentation (HTML user guide) can be accessed here.

Earlier preview versions of IBDfinder are also listed. The original version of the zip archive download contained the IBDfinder executable and the original PDF version of the feature guide. Updates to the feature guide were included separately in later bundles. (These updates have now been incorporated into the online HTML version of the guide.)

IBDfinder is currently tested only on Windows XP SP2 and Vista SP1. The .NET framework 2.0 must be installed. (Available through Windows Update or the Microsoft Download Centre.) Installation of IBDfinder is not required: simply run the program from the directory into which it is extracted.

Please mail Ian Carr with queries or comments on IBDfinder.


If you are using Affymetrix SNP5 or SNP6 genotype data, or data extracted by the Genotyping Console version 2 or above, the files must either be exported with each SNP's position, chromosome, RS name and Affymetrix ID data or be annotated using SNPannotator.
