=head1 DESCRIPTION

=head2 Object cDNA

=over

=item baseseq

 Type [Sequence *] Scalar No documentation



=back

No documentation for cDNA

=head2 Member functions of cDNA

=over

=item truncate_cDNA

&Wise2::cDNA::truncate_cDNA(cdna,start,stop)

  Truncates a cDNA sequence. Basically uses
  the /magic_trunc_Sequence function (of course!)

  It does not alter cdna, rather it returns a new
  sequence with that truncation



  Argument cdna         [READ ] cDNA that is truncated [cDNA *]
  Argument start        [UNKN ] Undocumented argument [int]
  Argument stop         [UNKN ] Undocumented argument [int]
  Return [UNKN ] Undocumented return value [cDNA *]


=item read_fasta_file_cDNA

&Wise2::cDNA::read_fasta_file_cDNA(filename)

  Reads a fasta file assumming that it is cDNA. 
  Will complain if it is not, and return NULL.



  Argument filename     [UNKN ] filename to be opened and read [char *]
  Return [UNKN ] Undocumented return value [cDNA *]


=item cDNA_name

&Wise2::cDNA::cDNA_name(cdna)

  Returns the name of the cDNA



  Argument cdna         [UNKN ] Undocumented argument [cDNA *]
  Return [UNKN ] Undocumented return value [char *]


=item cDNA_length

&Wise2::cDNA::cDNA_length(cdna)

  Returns the length of the cDNA



  Argument cdna         [UNKN ] Undocumented argument [cDNA *]
  Return [UNKN ] Undocumented return value [int]


=item cDNA_seqchar

&Wise2::cDNA::cDNA_seqchar(cdna,pos)

  Returns sequence character at this position.



  Argument cdna         [UNKN ] cDNA [cDNA *]
  Argument pos          [UNKN ] position in cDNA to get char [int]
  Return [UNKN ] Undocumented return value [char]


=item cDNA_from_Sequence

&Wise2::cDNA::cDNA_from_Sequence(seq)

  makes a new cDNA from a Sequence. It 
  owns the Sequence memory, ie will attempt a /free_Sequence
  on the structure when /free_cDNA is called

  If you want to give this cDNA this Sequence and
  forget about it, then just hand it this sequence and set
  seq to NULL (no need to free it). If you intend to use 
  the sequence object elsewhere outside of the cDNA datastructure
  then use cDNA_from_Sequence(/hard_link_Sequence(seq))




  Argument seq          [OWNER] Sequence to make cDNA from [Sequence *]
  Return [UNKN ] Undocumented return value [cDNA *]


=item hard_link_cDNA

&Wise2::cDNA::hard_link_cDNA(obj)

  Bumps up the reference count of the object
  Meaning that multiple pointers can 'own' it



  Argument obj          [UNKN ] Object to be hard linked [cDNA *]
  Return [UNKN ] Undocumented return value [cDNA *]


=item alloc

&Wise2::cDNA::alloc(void)

  Allocates structure: assigns defaults if given 



  Return [UNKN ] Undocumented return value [cDNA *]


=item set_baseseq

&Wise2::cDNA::set_baseseq(obj,baseseq)

  Replace member variable baseseq
  For use principly by API functions



  Argument obj          [UNKN ] Object holding the variable [cDNA *]
  Argument baseseq      [OWNER] New value of the variable [Sequence *]
  Return [SOFT ] member variable baseseq [boolean]


=item baseseq

&Wise2::cDNA::baseseq(obj)

  Access member variable baseseq
  For use principly by API functions



  Argument obj          [UNKN ] Object holding the variable [cDNA *]
  Return [SOFT ] member variable baseseq [Sequence *]
