i'm running the following code to manipulate numeric data in a vcf table.

```
 cat inputfile | while read row; do
                echo $row > tmp
                originalProb= `awk '{print $1}' tmp`
                probabilityHom1=`awk '{print $2}' tmp`
                probabilityHom2=`awk '{print $4}' tmp`
                numCols=`awk '{print NF}' tmp`

                if [ $numCols -gt 4 ]; then
                        echo "${originalProb}" >> currentRowGenotypes
                elif [ "$probabilityHom1" -gt "$probabilityHom2" ]; then
                        echo "1/1" >> currentRowGenotypes
                elif [ "$probabilityHom1" -lt "$probabilityHom2" ]; then
                        echo "0/0" >> currentRowGenotypes
                elif [ "$probabilityHom1" -eq "$probabilityHom2" ] && [ "$probabilityHom1" -eq 0 ]; then
                        echo "${originalProb}" >> currentRowGenotypes
                else                    
                        echo "het" >> currentRowGenotypes
                fi

        done

        cat tmpHeaders currentRowGenotypes > currentFullCol

```

the input file looks like this 

```
1/1     255     231     0
0/1     255     0       152
0/1     255     0       82
0/1     255     0       151
0/1     239     0       31
0/1     255     0       255

```

for some reason the awk command doesn't recognize the first column. any suggestions ?
