hello umaykulsum

As you do not ask for something nor point to particular errors i can only guess:

first i cannot understand how your data sample can be splitted using \t\s pattern (ah ok you are setting $/ for this..).

second i do not see where you are opening files (maybe the script is run under -nl ?)

If each file just contains 2 lines you can simply do:

my $key   = <$filehandle>; # first line
my $value = <$filehandle>; # second line

You also have no need to iterate over an array to get the count: @array in scalar context returns the numbers of elements. Also $#array contains the index of the last element ( so $#array + 1 == scalar @array ).

You also want the name of the file to be preserved somehow: you can read about $ARGV or you must create a sub that given the filename as arg, open it process it and store the filename along results.

A pray to you and to ALL BIONFORMATICS here around: sample data can be AGATC instead of a line of hundreds of chars? have readable data as sample help my eyes a lot!
