Human footprinting matrix used in the CART procedure. The file contains the original data file obtained from , the code used to transform them to files "genes.txt", "motifs.txt" and "upstream.txt", and the code used to load them to R data format. File "upstream.txt" contains a text plain matrix with genes in rows and predicted transcription factor binding site motifs in columns, adopting the value 0 when no TF binding site motif is predicted or the number of TF binding site motifs predicted by PRIMA.

Function codes and routines implemented in R for the CART procedure. The file contains the files used in CART procedure: onetree.R is used to train a single tree, consolide.R is used to summarize the 1,500 trees to obtain the gene score and rankvars.R is used to determine the score of the variables (TF binding sites motifs). Finally, Makefile is used to coordinate all computations using GNU make.
