## In the current working directory
bedFile <- system.file("extdata", "genoUpdatedData.bed", package="Gimpute")
bimFile <- system.file("extdata", "genoUpdatedData.bim", package="Gimpute") 
famFile <- system.file("extdata", "genoUpdatedData.fam", package="Gimpute")
system(paste0("scp ", bedFile, bimFile, famFile, " ."))  
sampleMissCutOff <- 0.02
inputPrefix <- "genoUpdatedData" 
outputPrefix <- "2_05_removedInstMiss"
