    BLAST E-values: how they are calculated and what they mean. A crucial measure that accompanies every hit sequence that BLAST identifies is the E -value, from E xpectation value. (aka, E value, e-value, evalue). Here, we’ll walk through: What is an E -value? How it is calculated? How to interpret it?
