This is a web tool to create artificial data sets for testing pattern discovery programs. Artificial sequences are generated according to a certain nucleotide distribution with a set of embedded motifs from the ABS database. The motifs are planted in a subset of similar positions to simulate the existance of related motifs in a set of orthologous or co-regulated genes from a microarray experiment. A graphical representation of the produced data set is also displayed.

- Length: size of each artificial sequence (bp)
- Number of sequences: size of the data set
- Number of planted motifs: motifs included on each sequence
- Species: a specific data set to detect motifs from this species will be produced
- Nucleotide distribution: A,C,G,T content of the random regions between planted motifs
- Probability to plant a motif: probability to insert a motif in a sequence
- TF name: planted motifs are associated to these TFs

This is an artificial data set produced by this application.
