Synopsis
    * creating a database object by connecting to the existing JASPAR6-type database
    
my $db = TFBS::DB::JASPAR6->connect("dbi:mysql:JASPAR6:myhost",
"myusername",
"mypassword");

    * retrieving a TFBS::Matrix::* object from the database
    
# retrieving a PFM by ID
my $pfm = $db->get_Matrix_by_ID('M0079','PFM');

#retrieving a PWM by name
my $pwm = $db->get_Matrix_by_name('NF-kappaB', 'PWM');

    * retrieving a set of matrices as a TFBS::MatrixSet object according to various criteria
    * creating a new JASPAR6-type database named MYJASPAR6:
    * storing a matrix in the database (currently only PFMs):
    
#let $pfm is a TFBS::Matrix::PFM object
$db->store_Matrix($pfm);

Description
TFBS::DB::JASPAR is a read/write database interface module that
retrieves and stores TFBS::Matrix::* and TFBS::MatrixSet
objects in a relational database. The interface is nearly identical
to the JASPAR2 and JASPAR4 interface, while the underlying data model is different

Methods description
connectcode    nextTop
 Title   : connect
Usage : my $db =
TFBS::DB::JASPAR6->connect("dbi:mysql:DATABASENAME:HOSTNAME",
"USERNAME",
"PASSWORD");
Function: connects to the existing JASPAR6-type database and
returns a database object that interfaces the database
Returns : a TFBS::DB::JASPAR6 object
Args : a standard database connection triplet
("dbi:mysql:DATABASENAME:HOSTNAME", "USERNAME", "PASSWORD")
In place of DATABASENAME, HOSTNAME, USERNAME and PASSWORD,
use the actual values. PASSWORD and USERNAME might be
optional, depending on the user's acces permissions for
the database server.
dbhcodeprevnextTop
 Title   : dbh
Usage : my $dbh = $db->dbh();
$dbh->do("UPDATE matrix_data SET name='ADD1' WHERE NAME='SREBP2'");
Function: returns the DBI database handle of the MySQL database
interfaced by $db; THIS IS USED FOR WRITING NEW METHODS
FOR DIRECT RELATIONAL DATABASE MANIPULATION - if you
have write access AND do not know what you are doing,
you can severely corrupt the data
For documentation about database handle methods, see DBI
Returns : the database (DBI) handle of the MySQL JASPAR2-type
relational database associated with the TFBS::DB::JASPAR2
object
Args : none
delete_Matrix_having_IDcodeprevnextTop
 Title   : delete_Matrix_having_ID
Usage : $db->delete_Matrix_with_ID('M00045.1');
Function: Deletes the matrix having the given ID from the database
Returns : 0 on success; $@ contents on failure
(this is too C-ike and may change in future versions)
Args : (ID)
A string. Has to be a matrix ID with version suffix in JASPAR6.
Comment : Yeah, yeah, 'delete_Matrix_having_ID' is a stupid name
for a method, but at least it should be obviuos what it does.
get_MatrixSetcodeprevnextTop
 Title   : get_MatrixSet
Usage : my $matrixset = $db->get_MatrixSet(%args);
Function: fetches matrix data under for all matrices in the database
matching criteria defined by the named arguments
and returns a TFBS::MatrixSet object
Returns : a TFBS::MatrixSet object
Args : This method accepts named arguments, corresponding to arbitrary tags, and also some utility functions
Note that this is different from JASPAR2 and to some extent JASPAR4. As any tag is supported for
database storage, any tag can be used for information retrieval.
Additionally, arguments as 'name','class','collection' can be used (even though
they are not tags.
Per default, only the last version of the matrix is given. The only way to get older matrices out of this
to use an array of IDs with actual versions like MA0001.1, or set the argyment -all_versions=>1, in which case you get all versions for each stable ID

Examples include: Fundamental matrix features -all # gives absolutely all matrix entry, regardless of versin and collection. Only useful for backup situations and sanity checks. Takes precedence over everything else -ID # a reference to an array of stable IDs (strings), with or without version, as above. tyically something like "MA0001.2" . Takes precedence over everything salve -all -name # a reference to an array of # transcription factor names (string). Will only take latest version. NOT a preferred way to access since names change over time -collection # a string corresponding to a JASPAR collection. Per default CORE -all_versions # gives all matrix versions that fit with rest of criteria, including obsolete ones.Is off per default. # Typical usage is in combiation with a stable IDs withou versions to get all versinos of a particular matrix Typical tag queries: These can be either a string or a reference to an array of strings. If it is an arrau it will be interpreted as as an "or"s statement -class # a reference to an array of # structural class names (strings) -species # a reference to an array of # NCBI Taxonomy IDs (integers) -taxgroup # a reference to an array of # higher taxonomic categories (string) Computed features of the matrices -min_ic # float, minimum total information content # of the matrix. -matrixtype #string describing type of matrix to retrieve. If left out, the format will revert to the database format, which is PFM.
The arguments that expect list references are used in database
query formulation: elements within lists are combined with 'OR'
operators, and the lists of different types with 'AND'. For example,
    my $matrixset = $db->(-class => ['TRP_CLUSTER', 'FORKHEAD'],
-species => ['Homo sapiens', 'Mus musculus'],
);
gives a set of TFBS::Matrix::PFM objects (given that the matrix models are stored as such)
whose (structural clas is 'TRP_CLUSTER' OR'FORKHEAD') AND (the species they are derived
from is 'Homo sapiens'OR 'Mus musculus').
As above, unless IDs with version numbers are used, only one matrix per stable ID wil be returned: the matrix with the highest version number
The -min_ic filter is applied after the query in the sense that the
matrices profiles with total information content less than specified
are not included in the set.
get_Matrix_by_IDcodeprevnextTop
 Title   : get_Matrix_by_ID
Usage : my $pfm = $db->get_Matrix_by_ID('M00034', 'PFM');
Function: fetches matrix data under the given ID from the
database and returns a TFBS::Matrix::* object
Returns : a TFBS::Matrix::* object; the exact type of the
object depending on what form the matrix is stored
in the database (PFM is default)
Args : (Matrix_ID)
Matrix_ID id is a string which refers to the stable
JASPAR ID (usually something like "MA0001") with
or without version numbers. "MA0001" will give the
latest version on MA0001, while "MA0001.2" will give
the second version, if existing. Warnings will be
given for non-existing matrices.
get_Matrix_by_namecodeprevnextTop
 Title   : get_Matrix_by_name
Usage : my $pfm = $db->get_Matrix_by_name('HNF-1');
Function: fetches matrix data under the given name from the
database and returns a TFBS::Matrix::* object
Returns : a TFBS::Matrix::* object; the exact type of the object
depending on what form the matrix object was stored in
the database (default PFM))
Args : (Matrix_name)

Warning : According to the current JASPAR6 data model, name is
not necessarily a unique identifier. Also, names change
over time.
In the case where
there are several matrices with the same name in the
database, the function fetches the first one and prints
a warning on STDERR. You've been warned.
Some matrices have multiple versions. The function will
return the latest version. For specific versions, use
get_Matrix_by_ID($ID.$version)
get_TFFM_by_IDcodeprevnextTop
 Title   : get_TFFM_by_ID
Usage : my $tffm = $db->get_TFFM_by_ID('TFFM0001');
Function: fetches TFFM data under the given ID from the
database and returns a TFBS::TFFM object.
Returns : a TFBS::TFFM object
Args : TFFM ID
TFFM_ID id is a string which refers to the stable
JASPAR TFFM ID (usually something like "TFFM0001") with
or without version numbers. "TFFM0001" will give the
latest version on TFFM0001, while "TFFM0001.2" will give
the second version, if existing. Warnings will be
given for non-existing TFFMs.
get_TFFM_by_matrix_IDcodeprevnextTop
 Title   : get_TFFM_by_matrix_ID
Usage : my $tffm = $db->get_TFFM_by_matrix_ID('MA0001.1');
Function: fetches TFFM data under related to the given matrix ID from the
database and returns a TFBS::TFFM object.
Returns : a TFBS::TFFM object
Args : Matrix ID
Matrix ID id is a string which refers to the stable
JASPAR matrix ID (usually something like "MA0148.3").
Note that this *should* be a fully qualified matrix ID (with
version) as the TFFM is related to a specific version of a
matrix. If no matrix version is given, the latest version of
the matrix is retrieved and the corresponding TFFM for that
matrix version is retrieved (could be no TFFM).
In general only a few matrices have associated TFFMs so in many
cases no TFFM will be retrieved. In these cases we return undef.
get_TFFM_by_namecodeprevnextTop
 Title   : get_TFFM_by_name
Usage : my $tffm = $db->get_TFFM_by_name('HNF-1');
Function: fetches TFFM data under the given name from the
database and returns a TFBS::TFFM object
Returns : a TFBS::TFFM object
Args : A TFFM name - the name of the transcription factor for which
this TFFM was modelled. This is the same as the name of the
matrix used to train the TFFM.

Warning : According to the current JASPAR data model, name is
not necessarily a unique identifier. Also, names change
over time.
In the case where there are several TFFMs with the same name in
the database, the function fetches the first one and prints
a warning on STDERR. You've been warned.
Some matrices have multiple versions. The function will
return the latest version. For specific versions, use
get_TFFM_by_ID($ID.$version)
newcodeprevnextTop
 Title   : new
Usage : DEPRECATED - for backward compatibility only
Use connect() or create() instead
store_MatrixcodeprevnextTop
 Title   : store_Matrix
Usage : $db->store_Matrix($matrixobject);
Function: Stores the contents of a TFBS::Matrix::DB object in the database
Returns : 0 on success; $@ contents on failure
(this is too C-like and may change in future versions)
Args : (PFM_object)
A TFBS::Matrix::PFM, FBS::Matrix::PWM or FBS::Matrix::ICM object.
PFM object are recommended to use, as they are eaily converted to
other formats
# might have to give version and collection here
Comment : this is an experimental method that is not 100% bulletproof;
use at your own risk

General documentation
JASPAR6 DATA MODELTop
JASPAR6 is working name for a relational database model used
for storing transcriptional factor pattern matrices in a MySQL database.
It was initially designed (JASPAR2) to store matrices for the JASPAR database of
high quality eukaryotic transcription factor specificity profiles by
Albin Sandelin and Wyeth W. Wasserman. Besides the profile matrix itself,
this data model stores profile ID (unique), name, structural class,
basic taxonomic and bibliographic information
as well as some additional, and custom, tags.
Here goes a moore thorough description on tables and IDs


----------------------- ADVANCED ---------------------------------
For the developers and the curious, here is the JASPAR6 data model:
  
MISSING TEXT HEER ON HOW IT WORKS
It is our best intention to hide the details of this data model, which we
are using on a daily basis in our work, from most TFBS users.
Most users should only know the methods to store the data and
which tags are supported.
