Post #7 probably did not work for you because there are excess trailing spaces that need to be removed in the file samples, but that are not going to be present in the actual FASTA files, see the note underneath...
--
Here they are without the spaces:
File1:
File2:
Of course another thing is the order that is mixed up when because it is undefined in the array structure in awk. That could easily be fixed of course if need be.

Hey,
I've been trying to break a massive fasta formatted file into files containing each gene separately. Could anyone help me? I've tried to use the following code but i've recieved errors every time:

Hii,
Could someone help me to append string to the starting of all the filenames inside a directory but it should exclude .zip files and subdirectories.

Bio::Index::Fasta(3pm) User Contributed Perl Documentation Bio::Index::Fasta(3pm)NAME
Bio::Index::Fasta - Interface for indexing (multiple) fasta files
SYNOPSIS
# Make an index for one or more fasta files
use Bio::Index::Fasta;
use strict;
my $Index_File_Name = shift;
my $inx = Bio::Index::Fasta->new(-filename => $Index_File_Name,
-write_flag => 1);
$inx->make_index(@ARGV);
# Once the index is made it can accessed, either in the
# same script or a different one
use Bio::Index::Fasta;
use strict;
my $Index_File_Name = shift;
my $inx = Bio::Index::Fasta->new(-filename => $Index_File_Name);
my $out = Bio::SeqIO->new(-format => 'Fasta',
-fh => *STDOUT);
foreach my $id (@ARGV) {
my $seq = $inx->fetch($id); # Returns Bio::Seq object
$out->write_seq($seq);
}
# or, alternatively
my $id;
my $seq = $inx->get_Seq_by_id($id); # identical to fetch()
DESCRIPTION
Inherits functions for managing dbm files from Bio::Index::Abstract.pm, and provides the basic funtionallity for indexing fasta files, and
retrieving the sequence from them. For best results 'use strict'.
Bio::Index::Fasta supports the Bio::DB::BioSeqI interface, meaning it can be used as a Sequence database for other parts of bioperl
Additional example code is available in scripts/index/*PLS and in the Bioperl Tutorial (<http://www.bioperl.org/wiki/Bptutorial.pl>)
Note that by default the key for the sequence will be the first continuous string after the '>' in the fasta header. If you want to use a
specific substring of the fasta header you must use the id_parser() method.
You can also set or customize the unique key used to retrieve by writing your own function and calling the id_parser() method. For
example:
$inx->id_parser(&get_id);
# make the index
$inx->make_index($file_name);
# here is where the retrieval key is specified
sub get_id {
my $line = shift;
$line =~ /^>.+gi|(d+)/;
$1;
}

APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
_file_format
Title : _file_format
Function: The file format for this package, which is needed
by the SeqIO system when reading the sequence.
Returns : 'Fasta'
_index_file
Title : _index_file
Usage : $index->_index_file( $file_name, $i )
Function: Specialist function to index FASTA format files.
Is provided with a filename and an integer
by make_index in its SUPER class.
Example :
Returns :
Args :
id_parser
Title : id_parser
Usage : $index->id_parser( CODE )
Function: Stores or returns the code used by record_id to
parse the ID for record from a string. Useful
for (for instance) specifying a different
parser for different flavours of FASTA file.
Returns &default_id_parser (see below) if not
set. If you supply your own id_parser
subroutine, then it should expect a fasta
description line. An entry will be added to
the index for each string in the list returned.
Example : $index->id_parser( &my_id_parser )
Returns : ref to CODE if called without arguments
Args : CODE
default_id_parser
Title : default_id_parser
Usage : $id = default_id_parser( $header )
Function: The default Fasta ID parser for Fasta.pm
Returns $1 from applying the regexp /^>s*(S+)/
to $header.
Returns : ID string
Args : a fasta header line string
