DESCRIPTION

TFBS::TFFM is a class to hold basic information about a TFFM. It was mainly designed to store the information about a TFFM stored in the TFFM table of the JASPAR DB newly introduced in the JASPAR 2016 version. It does NOT (currently) store the actual XML describing the the model but this would be simple to add. At the time of this writing the relationship between JASPAR matrices as stored in the MATRIX table and TFFMs was not completely clear and the matrix IDs related to a TFFM are stored in the TFFM table. The relationship could be 1:n, m:1 or m:n in the future so this may well be changed and a joining table created to facilitate this.

 Title   : ID
 Usage   : my $id = $tffm->ID();
 Function: Get/set the ID of this TFFM.
 Returns : The ID of this TFFM.
 Args    : None for get or a new string ID.

name

 Title   : name
 Usage   : my $name = $tffm->name();

 Returns : Log(p) value of the 1st-order model.
 Args    : None for get or a new 1st-order log(p) value.

log_p_detailed

 Title   : log_p_detailed
 Usage   : my $log_p_val = $tffm->log_p_detailed();

 Returns : Log(p) value of the detailed model.
 Args    : None for get or a new detailed log(p) value.

matrix_ID

 Title   : matrix_ID
 Usage   : my $matrix_id = $tffm->matrix_ID();
 Function: Get/set the ID of the matrix associated to this TFFM.
 Returns : ID of the matrix associated to this TFFM.

matrix

 Title   : matrix
 Usage   : my $matrix = $tffm->matrix();
 Function: Get/set the matrix object related to this TFFM
 Returns : A reference to TFBS::Matrix object which was used to train the
           TFFM.
 Args    : None for get or a new TFBS::Matrix object reference.
