Output The output file is called 'MQLStest.out'. It has General information : number of individuals, number of independent families For each marker, - among those genotyped at the marker, the numbers who are affected, unaffected, and of unknown phenotype, respectively, - value of the MQLS statistic and corresponding p-value using the chi-squared null distribution. - value of the corrected chi-squared statistic and corresponding p-value using the chi-squared null distribution - value of the WQLS statistic and corresponding p-value using the chi-squared null distribution. - the signs of the MQLS and WQLS quasi-scores associated to each allele when the p-value is smaller than 0.05, in order to know the direction of the change in allele frequency associated with the MQLS or WQLS result. - a warning message is printed when some allele counts are small, a situation in which the chi2 asymptotic null distribution might not provide accurate p-values - allele frequencies and s.d.'s estimated using the quasi-likelihood score function proposed by McPeek, Wu and Ober (2003) in the case sample, the control sample and the case+control sample. - allele frequencies estimated by naive counting in the case sample, the control sample and the whole case+control sample A file called 'MQLStest.top' contains the top 20 markers with the smallest p-values. The number of markers output to this file can be decreased or increased by the user by changing MAXTOP (currently set to 20) in the MQLS.c source file. A file called 'MQLStest.pvalues' lists the p-values for every SNP for MQLS, corrected chi-squared statistic, and WQLS. An error file called 'MQLStest.err' may contain warnings - when lines have incorrect number of fields in the marker data file - when individuals from the kinship coefficient file are not listed in the marker data file
