filter.samples: FALSEilter X, Y and genotype data by call rate

In dmgatti/DOQTL: Genotyping and QTL Mapping in DO Mice

FALSEilter X, Y and genotype data by call rate

Description

This function reads in "x.txt", "y.txt", "geno.txt" and "call.rate.batch.txt" from the user specified input directory and removes samples with a call rate less than the supplied threshold (default = 0.9). It then writes the files out to "x.filt.txt", "y.filt.txt", "geno.filt.txt" and "call.rate.batch.filt.txt".

Usage

  filter.samples(path = ".", thr = 0.9)

Arguments

path	Character, the full path to the directory where the files reside.
thr	Numeric, call rate threshold below which samples will be removed. Default = 0.9.

Value

data.frame with the sample IDs and call rates of the removed samples. The intensity and genotype files are written to the input directory.
