Hello Monks,

I'd like to read a Fasta file, consisting of header1 newline sequence1 newline header2 newline... into a hash and print it out.

I am currently learning hashes, and I don't understand why my program doesn't work. It reads all sequences into one element and doesn't store the headers at all

all headers start with a '>', so I use a regex to identify them, here's my code:

my $file = "sequences.fasta";
open (READ, "$file") || die "Cannot open $file: $!.\n";

my %seqs = ();
my $header = '';

while (my $line = <READ>){
    chomp $line;
    $line =~ s/^\s*$//;
    if ($line =~ m/^>.*$/){
        $line = $header;
    } else {
        $seqs{"$header"} .= $line;
    }
}
close (READ);

my @count_seq = keys %seqs;
foreach (@count_seq){
    print $_, "\n", $seqs{$_}, "\n";
}

can someone indicate the problem? Thanks in advance!
