  1. Top 25 overrepresented words for the proximal promoters in Arabidopsis thaliana. The Word attribute describes the short nucleotide sequence associated with a putative word. S and ES describe the number of sequences a word occurs in and the number of sequences the word was expected to occur in respectively, while O and EO describe the total number of occurrences and the expected total number of occurrences. The score SlnSES describes a statistical coverage of the sequences analyzed in the set and is based on a Markov Chain Background Model. Each set of attributes was computed for the masked as well as the unmasked version of the corresponding segment with the emphasis placed on the unmasked version (i.e. sorting of the table based on the unmasked SlnSES score).
  2. Further information for the word is provided through its reverse complement (RevComp) and the position of the reverse complement in the set of results (RC_Pos) as well as a notion describing if the word is a genomic palindrome (Pal).
  3. Finally, PValues describes a p-value that is assigned in order to provide statistical insight allowing the determination if a word is relevant or was discovered as interesting by random chance.
