STRAT version 1.1The program STRAT is a companion program to structure. It is written for use in association mapping, enabling valid case-control studies even in the presence of population structure. This method was described in an article in Am. J. Hum Genet (67:170-181). [Abstract][Manuscript]. See also Am. J. Hum Genet (65: 220-228) [Abstract], [Manuscript], [Review of structured association methods].

Bug in version 1.01
Version 1.1 corrects a serious bug that was introduced into STRAT version 1.01 (September 2002). In the situations where this bug arose, it produced nonsensical output: massive chi-square values and undefined values of the test statistic.
Version 1.1 also introduces a number of minor updates to improve user-friendliness, described in the updated manual.
