Web5 de mar. de 2024 · as well as its E-value, or “expect score”. The E-value indicates the number of alignments with that particular bit score that would be expected to occur solely by chance in the search space. Alignments with the highest bit scores (and lowest E-values) are listed at the top of the table. WebFor example, an E value of 1 assigned to an alignment means that in a database of the same size one expects to see 1 match with a similar score, or higher, simply by chance. The lower the E-value the more “significant” the match is. However, keep in mind that virtually identical short alignments have relatively high E values.
