HWE and Inbreeding estimates
Filipe G. Vieira has been extending the ANGSD feature set by
- A method for estimating inbreeding (deviation from Hardy-Weinberg) based on output from ANGSD.
- Some parts of the ANGSD code will work for inbreeding estimates.
To compile angsd with support for deviations from HWE in the frequency estimates you need to
cd angsd0.539/ make inbreed
Verify that it worked by
./angsd_inbreed -doMaf ommand: ./angsd_inbreed -doMaf -> angsd version: 0.539 build(Jun 25 2013 13:27:43) -> Analysis helpbox/synopsis information: ------------------------ analysisMaf.inbreed.cpp: -doMaf 0 1: BFGS frequency (known major minor) 2: EM frequency (known major minor) 4: BFGS frequency (unknown major minor) 8: EM frequency (unknown major minor) 16: frequency from genotype probabilities 32: alleleCounts based method (known major minor) -doSNP 0 -minMaf 0.010000 0 -minLRT 24.000000 0 -ref (null) -anc (null) -doZ 0 -eps 0.001000 [Only used for -doMaf &32] -indFname (null) (file containing individual inbreedcoeficients) NB these frequency estimators requires major/minor -doMajorMinor
