ANGSD: Analysis of next generation Sequencing Data
Latest tar.gz version is (0.938/0.939 on github), see Change_log for changes, and download it here.
HWE test
Test for Hardy Weinberg equilibrium based on genotype likelihoods. This class works both as a filter for all other classes and outputs the results in a file.
If you want to estimate inbreeding for individuals or include inbreeding information in your analysis try [HWE_and_Inbreeding_estimates].
Brief Overview
./angsd -HWE_pval -> angsd version: 0.911-12-gddb6f5f-dirty (htslib: 1.3-1-gc72ae90) build(Apr 10 2016 16:36:30) -> Analysis helpbox/synopsis information: -> Command: ../angsd/angsd -HWE_pval -> Sun Apr 10 16:53:24 2016 ------------- abcHWE.cpp: -HWE_pval 0.000000
Use as a filter
- -HWE_pval [float]
p-value threshold. The value must be above 0 and a maximum of 1. Sites with a p-value below this threshold will be removed.
Output
This function will also print the results of the selected sites. If you choose -HWE_pval 1 then all sites (that pass other filters) will be outputted.
