Llr computes the probability distribution for the log-likelihood ratio (LLR) of N letters. If a range for N is given, the distributions for each value in the range are computed. If fraction (frac parameter) is given, then only the most probable fraction of values are used to speed the calculation.

MEME is a tool for discovering motifs in a group of related DNA or protein sequences. MEME takes as input a group of DNA or protein sequences and outputs as many motifs as requested up to a user-specified statistical confidence threshold. MEME uses statistical modeling techniques to automatically choose the best width, number of occurrences, and description for each motif.
