filter.control: Set options for quality control filtering of data.
Description
Set options for quality control filtering of data.
Usage
filter.control(filter=TRUE, snpcallrate=.9, MAF=.01, samplecallrate=.9,
HWEp=.001)
Arguments
filter
Should data filtering be done? Default is TRUE
.
snpcallrate
The SNP call rate is the proportion of non-missing genotypes in the
study per SNP.
SNPs with call rate less than snpcallrate
are removed.
The default value is 0.90.
MAF
The minimum minor allele frequency (MAF) for SNPs.
SNPs with MAF less than MAF
are removed.
The default value is 0.01.
samplecallrate
The proportion of SNPs for a sample that had genotype calls.
Samples with call rate less than samplecallrate
are removed.
The default value is 0.90.
HWEp
Threshold for the p-value from a 2-sided test of HWE.
SNPs with p-value less than HWEp
are removed.
The default value is 0.001.
Value
A list whose components are the function inputs.
