A matrix is a representation of a profile. The matrix has the nucleotides as row labels and equence position as column labels. A matrix also includes annotation in the form of tags consisting of name and value. This is the Adenine row in the matrix. This is the Thymine row in the matrix. This is the Cytosine row in the matrix. This is the Guanine row in the matrix. This is a collection of tags that contain annotation of the matrix. The format of this Matrix. This is usually Position Frequency Matrix, Position Weight Matrix or Information Content Matrix. A identifier for this matrix This element represents a row in tha matrix. This is a collection of columns for this row. This is a type that contains annotation information. The name of this tag. The values of this tag. This element indicates one of the Jaspar sub-databases. This element indicates the format of a matrix. It can be either PFM, PWM or ICM. The tags used to seach the database with. The name of a matrix. The Id of a matrix. Fetch a Matrix by it's name.

This is a Web service interface to the Jaspar database which contain profiles of transcription factor binding sites. Profiles can be fetched as Position Frequency Matrices (PFM), Position Weight Matrices (PWM), or Information Content Matrices (ICM).
