Parsing Text


I'm learning Perl and I have a challenge to do in Bioinformatics.

I have a CSV file with a lot of columns and rows... but I need to sum cells of certain column:

Samples Name Value1 Value2 Value3.....
A Name 1 32 27 21
B Name 2 23 12 13
C Name 3 10 98 59
D Name 4 21 78 72
E Name 5 32 72 27
... ... ... ... ...

So I need Sum of cells in column Value 1, Sum of cells in column Value2 and so on.

I know this is basic and I'm studying as hard as I can.

Could anyone help me?

CODE --> command-line

perl -nae 'if($.==1){@h=@F;next}$s[$i]+=$v while($i,$v)=each@F;END{print"$h[$_] : $s[$_]\n"for 2..$#h}' /input/file
