Problem with AWK and OFS

I have a file that looks like this:

Infile.seq
Quote:
"Contig 1" (1,314)
Contig Length: 314 bases
Average Length/Sequence: 257 bases
Total Sequence Length: 515 bases
Top Strand: 1 sequences
Bottom Strand: 1 sequences
Total: 2 sequences
FEATURES Location/Qualifiers
coverage_once 1..56
/Note="Only_once"
coverage_below 57..257
/Note="Below threshold"
coverage_once 258..314
/Note="Only_once"
^^
TTTGGATATGATGATGAACTGGTCACCTACAACGGCCCTGGTGGTATCGCAGTTACTCCGGATCCCACAAGCTGTCGTGGATATGGTGGCGGGGGCCC
I want to output the DNA sequence and add the filename as the identifier. The output file should look like this:

Quote:
>Infile.seq
TTTGGATATGATGATGAACTGGTCACCTACAACGGCCCTGGTGGTATCGCAGTTACTCCGGATCCCACAAGCTGTCGTGGATATGGTGGCGGGGGCCC
I am using the following code but I do not understand why the sequence is not in the output:

Code:
awk 'BEGIN { RS = "^^"; FS="\n"; OFS ="\n" }{print ">"FILENAME OFS}' Infile.seq

Any help will be greatly appreciated!

Bio::Factory::SequenceFactoryI(3pm)			User Contributed Perl Documentation		       Bio::Factory::SequenceFactoryI(3pm)

NAME
Bio::Factory::SequenceFactoryI - This interface allows for generic building of sequences in factories which create sequences (like SeqIO) SYNOPSIS
# do not use this object directly it is an interface # get a Bio::Factory::SequenceFactoryI object like use Bio::Seq::SeqFactory; my $seqbuilder = Bio::Seq::SeqFactory->new('-type' => 'Bio::PrimarySeq'); my $seq = $seqbuilder->create(-seq => 'ACTGAT', -display_id => 'exampleseq'); print "seq is a ", ref($seq), " "; DESCRIPTION
A generic way to build Sequence objects via a pluggable factory. This reduces the amount of code that looks like if( $type eq 'Bio::PrimarySeq' ) { ... } elsif( $type eq 'Bio::Seq::RichSeq' ) { ... } FEEDBACK
Mailing Lists User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated. bioperl-l@bioperl.org - General discussion http://bioperl.org/wiki/Mailing_lists - About the mailing lists Support Please direct usage questions or support issues to the mailing list: bioperl-l@bioperl.org rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Bug reports can be submitted via the web: https://redmine.open-bio.org/projects/bioperl/ AUTHOR - Jason Stajich Email jason-at-bioperl.org APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _ create Title : create Usage : my $seq = $seqbuilder->create(-seq => 'CAGT', -id => 'name'); Function: Instantiates new Bio::PrimarySeqI (or one of its child classes) This object allows us to genericize the instantiation of sequence objects. Returns : Bio::PrimarySeqI Args : initialization parameters specific to the type of sequence object we want.
