for (( i=1; i<=$TotFGNumber; i++ ))
do
        awk -vFGNo=$i -F"\t" '$FGNo !~ /^$/ {print $FGNo}' FGFilename > "FGFile_"$i
done
for (( i=1; i<=$TotFGNumber; i++ ))
do
        file1="FGFile_"$i
        k=$(($i + 1))
        for (( j=k; j<=$TotFGNumber; j++ ))

                [ $LineCnt1 -lt $LineCnt2 ] && LineCount=$(( $LineCnt1 - 1 )) ||  LineCount=$(( $LineCnt2 - 1))
                CommonFieldNo=$(awk     'NR==FNR{a[$1]++;next} \
                        a[$1]' $file1 $file2 | wc -l)
                Comparision=$(echo "scale=5;$CommonFieldNo / $LineCount" | bc)
                echo "FG${i} vs FG${j} -  $Comparision"
