+We can generate a file with filters added for the rate missing data in individuals ''--mind'' and call rate for the SNPs ''--geno'' and also for the minor allele frequency //(MAF)// , with flag ''--maf''.
+The thresholds for these filters should be adjusted accordingly to the different data sets.
+<code>
+#### filter data ###
+plink --file ${file} \
+ --geno 0.05 \   #95% call rate of SNPs
+ --maf 0.01\     #SNPs with less than 1% minor allele frequencies
+ --mind 0.25 \   #individuals with more than 25% missing data
