NAME
Bio::SeqIO::phd - .phd file input/output stream
SYNOPSIS
Do not use this module directly. Use it via the Bio::SeqIO class.
DESCRIPTION
This object can transform .phd files (from Phil Green's phred basecaller) to and from Bio::Seq::SeqWithQuality objects

APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
next_seq()
Title : next_seq()
Usage : $swq = $stream->next_seq()
Function: returns the next phred sequence in the stream
Returns : Bio::Seq::SeqWithQuality object
Args : NONE
Notes : This is really redundant because AFAIK there is no such thing as
a .phd file that contains more then one sequence. It is included as
an interface thing and for consistency.
_next_phd()
Title : _next_phd()
Usage : $seq = $stream->_next_phd() (but do not do this. use next_seq()
instead.)
Function: returns the next phred sequence in the stream
Returns : Bio::Seq::SeqWithQuality object
Args : NONE
Notes : An internal method. Use next_seq.
next_primary_phd()
Title : next_primary_phd()
Usage : $seq = $stream->next_primary_phd()
Function: returns the next phred sequence in the stream
Returns : Bio::Seq::SeqWithQuality object
Args : NONE (huh?)
write_seq
Title : write_seq(-SeqWithQuality => $swq, <comments>)
Usage : $obj->write_seq( -SeqWithQuality => $swq,);
Function: Write out an scf.
Returns : Nothing.
Args : Requires: a reference to a SeqWithQuality object to form the
basis for the scf. Any other arguments are assumed to be comments
and are put into the comments section of the scf. Read the
specifications for scf to decide what might be good to put in here.
Notes : These are the comments that reside in the header of a phd file
at the present time. If not provided in the parameter list for
write_phd(), the following default values will be used:
CHROMAT_FILE: $swq->id()
ABI_THUMBPRINT: 0
PHRED_VERSION: 0.980904.e
CALL_METHOD: phred
QUALITY_LEVELS: 99
TIME: <current time>
TRACE_ARRAY_MIN_INDEX: 0
TRACE_ARRAY_MAX_INDEX: unknown
CHEM: unknown
DYE: unknown
