NAME

       Bio::PrimerDesigner::Table -- Draw HTML tables for PCR primer display

DESCRIPTION

       Draws simple HTML tables to display Bio::PrimerDesigner PCR primer design and e-PCR results for web applications.

METHODS

   info_table
       Prints a two-column table for generic, key-value style annotations.  Expects to be passed the name of the gene/feature/etc. and a hash of
       attributes. If there is an 'image' key, the value is assumed to be an image URL, which is printed in a double-wide cell at the bottom of
       the table.

	 my $gene	= 'Abc-1';
	 my %gene_info	= (
	     Chromosome => I,
	     Start	=> 100450,
	     Stop	=> 102893,
	     Strand	=> '+'
	 );

	 my $page = Bio::PrimerDesigner::Tables->new;
	 $page->info_table( $gene, %gene_info );

   PCR_header
       Returns a generic header for the PCR primer table.  Does not expect any argumments.

   PCR_set
       Returns the top row for the PCR primer table.  Expects the primer set number as its only argument.

   PCR_row
       Returns table rows with PCR primer info.  Should be called once for each primer pair.  Expects to be passed a hash containing the
       Bio::PrimerDesigner::Result object and the primer set number and an (optional) label.

	 my $pcr_row =	PCR_row(
	     primers => $result_obj,
	     setnum  => $set_number,
	     label   => $label
	 );

   ePCR_row
       Returns table rows summarizing e-PCR results.  Expects to be passed an Bio::PrimerDesigner::Result e-PCR results object and an optional
       e-PCR label.

   render
       Renders the image URL. Expects to be passed a hash of the map start and stop, and other features to be mapped (i.e.
       gene,forward_primer,reverse_primer, label,start and stop of each feature, and gene strand).

	 my $image =  $page->render(
	     start => $startleft,
	     stop  => $startright,
	     feat  => $features
	 );

   PCR_map
       Returns a 6 column wide table cell with the <IMG ...> info.  Will display the image of mapped primers in the browser when passed the image
       URL.

NAME

       Bio::SeqFeature::Primer - Primer Generic SeqFeature

SYNOPSIS

	# set up a single primer that can be used in a PCR reaction

	use Bio::SeqFeature::Primer;

	# initiate a primer with raw sequence
	my $primer=Bio::SeqFeature::Primer->new(-seq=>'CTTTTCATTCTGACTGCAACG');

	# get the primery tag for the primer # should return Primer
	my $tag=$primer->primary_tag;

	# get or set the location that the primer binds to the target at
	$primer->location(500);
	my $location=$primer->location(500);

	# get or set the 5' end of the primer homology, as the primer doesn't
	# have to be the same as the target sequence
	$primer->start(2);
	my $start=$primer->start;

	# get or set the 3' end of the primer homology
	$primer->end(19);
	my $end = $primer->end;

	# get or set the strand of the primer. Strand should be 1, 0, or -1
	$primer->strand(-1);
	my $strand=$primer->strand;

	# get or set the id of the primer
	$primer->display_id('test_id');
	my $id=$primer->display_id;

	# get the tm of the primer. This is calculated for you by the software.
	# however, see the docs.
	my $tm = $primer->Tm;

	print "These are the details of the primer:
	Tag:		$tag
	Location	$location
	Start:		$start
";
	print "	End:		$end
	Strand:		$strand
	ID:		$id
	Tm:		$tm
";

DESCRIPTION

       Handle primer sequences. This will allow you to generate a primer object required for a Bio::Seq::PrimedSeq object. This module is designed
       to integrate with Bio::Tools::Primer3 and Bio::Seq::PrimedSeq.

       In addition, you can calculate the melting temperature of the primer.

       This module is supposed to implement location and range, presumably through generic.pm, but does not do so yet. However, it does allow you
       to set primers, and use those objects as the basis for Bio::Seq::PrimedSeq objects.

       See also the POD for Bio::Seq::PrimedSeq and Bio::Tools::Nucleotide::Analysis::Primer3

APPENDIX

	       The rest of the documentation details each of the object
	       methods. Internal methods are usually preceded with a _

   new()
	Title	: new()
	Usage	: $primer = Bio::SeqFeature::Primer(-seq=>sequence_object);
	Function: Instantiate a new object
	Returns : A SeqPrimer object
	Args	: You must pass either a sequence object (preferable) or a sequence.

   seq()
	Title	: seq()
	Usage	: $seq = $primer->seq();
	Function: Return the sequence associated with this Primer.
	Returns : A Bio::Seq object
	Args	: None.

   source_tag()
	Title	: source_tag()
	Usage	: $tag = $feature->source_tag();
	Function: Returns the source of this tag.
	Returns : A string.
	Args	: If an argument is provided, the source of this SeqFeature
		  is set to that argument.

   location()
	Title	: location()
	Usage	: $tag = $primer->location();
	Function: Gets or sets the location of the primer on the sequence
	Returns : If the location is set, returns that, if not returns 0.
		  Note: At the moment I am using the primer3 notation of location
		  (although you can set whatever you want).
		  In this form, both primers are given from their 5' ends and a length.
		  In this case, the left primer is given from the leftmost end, but
		  the right primer is given from the rightmost end.
		  You can use start() and end() to get the leftmost and rightmost base
		  of each sequence.
	Args	: If supplied will set a location

   start()
	Title	: start()
	Usage	: $start_position = $primer->start($new_position);
	Function: Return the start position of this Primer.
		  This is the leftmost base, regardless of whether it is a left or right primer.
	Returns : The start position of this primer or 0 if not set.
	Args	: If supplied will set a start position.

   end()
	Title	: end()
	Usage	: $end_position = $primer->end($new_position);
	Function: Return the end position of this primer.
		  This is the rightmost base, regardless of whether it is a left or right primer.
	Returns : The end position of this primer.
	Args	: If supplied will set an end position.

   strand()
	Title	: strand()
	Usage	: $strand=$primer->strand()
	Function: Get or set the strand.
	Returns : The strand that the primer binds to.
	Args	:  If an argument is supplied will set the strand, otherwise will return it. Should be 1, 0 (not set), or -1

   display_id()
	Title	: display_id()
	Usage	: $id = $primer->display_id($new_id)
	Function: Returns the display ID for this Primer feature
	Returns : A scalar.
	Args	: If an argument is provided, the display_id of this primer is
		  set to that value.

   Tm()
	 Title	 : Tm()
	 Usage	 : $tm = $primer->Tm(-salt=>'0.05', -oligo=>'0.0000001')
	 Function: Calculates and returns the Tm (melting temperature) of the primer
	 Returns : A scalar containing the Tm.
	 Args	 : -salt  : set the Na+ concentration on which to base the calculation
			    (default=0.05 molar).
		 : -oligo : set the oligo concentration on which to base the
			    calculation (default=0.00000025 molar).
	 Notes	 : Calculation of Tm as per Allawi et. al Biochemistry 1997
		   36:10581-10594. Also see documentation at
		   http://www.idtdna.com/Scitools/Scitools.aspx as they use this
		   formula and have a couple nice help pages. These Tm values will be
		   about are about 0.5-3 degrees off from those of the idtdna web tool.
		   I don't know why.

		   This was suggested by Barry Moore (thanks!). See the discussion on
		   the bioperl-l with the subject "Bio::SeqFeature::Primer Calculating
		   the PrimerTM"

   Tm_estimate
	Title	: Tm_estimate
	Usage	: $tm = $primer->Tm_estimate(-salt=>'0.05')
	Function: Calculates and returns the Tm (melting temperature) of the primer
	Returns : A scalar containing the Tm.
	Args	: -salt set the Na+ concentration on which to base the calculation.
	Notes	: This is an estimate of the Tm that is kept in for comparative reasons.
		  You should probably use Tm instead!

		  This Tm calculations are taken from the Primer3 docs: They are
		  based on Bolton and McCarthy, PNAS 84:1390(1962)
		  as presented in Sambrook, Fritsch and Maniatis,
		  Molecular Cloning, p 11.46 (1989, CSHL Press).

		  Tm = 81.5 + 16.6(log10([Na+])) + .41*(%GC) - 600/length

		  where [Na+] is the molar sodium concentration, %GC is the
		  %G+C of the sequence, and length is the length of the sequence.

		  However.... I can never get this calculation to give me the same result
		  as primer3 does. Don't ask why, I never figured it out. But I did
		  want to include a Tm calculation here because I use these modules for
		  other things besides reading primer3 output.

		  The primer3 calculation is saved as 'PRIMER_LEFT_TM' or 'PRIMER_RIGHT_TM'
		  and this calculation is saved as $primer->Tm so you can get both and
		  average them!
