The statistical significance of the motif. MEME usually finds the most statistically significant (low E-value) motifs first. It is unusual to consider a motif with an E-value larger than 0.05 significant so, as an additional indicator, MEME displays these partially transparent.

The E-value of a motif is based on its log likelihood ratio, width, sites, the background letter frequencies (given in the command line summary), and the size of the training set.

The E-value is an estimate of the expected number of motifs with the given log likelihood ratio (or higher), and with the same width and site count, that one would find in a similarly sized set of random sequences (sequences where each position is independent and letters are chosen according to the background letter frequencies).

[ close ]

The number of sites contributing to the construction of the motif.

[ close ]

The width of the motif. Each motif describes a pattern of a fixed width, as no gaps are allowed in MEME motifs.

The log likelihood ratio of the motif.The log likelihood ratio is the logarithm of the ratio of the probability of the occurrences of the motif given the motif model (likelihood given the motif) versus their probability given the background model (likelihood given the null model). (Normally the background model is a 0-order Markov model using the background letter frequencies, but higher order Markov models may be specified via the -bfile option to MEME.).

[ close ]

The information content of the motif in bits. It is equal to the sum of the uncorrected information content, R(), in the columns of the pwm. This is equal relative entropy of the motif relative to a uniform background frequency model.

[ close ]

The relative entropy of the motif.

re = llr / (sites * ln(2))

[ close ]

The Bayes Threshold.

[ close ]

The strand used for the motif site.

+
The motif site was found in the sequence as it was supplied.
-
The motif site was found in the reverse complement of the supplied sequence.
[ close ]

The position in the sequence where the motif site starts. If a motif started right at the begining of a sequence it would be described as starting at position 1.

[ close ]

The probability that an equal or better site would be found in a random sequence of the same length conforming to the background letter frequencies.

[ close ]

A motif site with the 10 flanking letters on either side.

When the site is not on the given strand then the site and both flanks are reverse complemented so they align.

[ close ]

The name of the sequences as given in the FASTA file.

The number to the left of the sequence name is the ordinal of the sequence.

[ close ]

This is the combined match p-value.

The combined match p-value is defined as the probability that a random sequence (with the same length and conforming to the background) would have motif-sequence match p-values such that the product is smaller or equal to the value calulated for the sequence under test.

The motif-sequence match p-value is defined as the probability that a random sequence (with the same length and conforming to the background) would have a match to the motif under test with a score greater or equal to the largest found in the sequence under test.
