Hi sreya,
I would have love to see the result your code was giving. However, If I may advice I will say use warnings and strict in your perl code ALWAYS. There are also several modern way of doing what you want done. Like your open, using a 3-arguments is preferred.
All that been said, you could get around your code issue like so:
use warnings;
use strict;
use Data::Dumper;
my %data;
my $header;
while (<DATA>) {
chomp;
next if /^$/; # skip on blanck line
if (/^>\D+?(\d+?)$/) {
$header = $1;
}
else {
$data{$header}{$_}++ for split //, $_;
}
}
print Dumper \%data;
__DATA__
>header1
aaaaabbbb
ccccddd
>header2
ggggg
jjj
kkkk
OUTPUT:
$VAR1 = {
'1' => {
'a' => 5,
'b' => 4,
'c' => 4,
'd' => 3
},
'2' => {
'g' => 5,
'j' => 3,
'k' => 4
}
};
How to display the output as desired, that is for the OP! :)
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
