[i] (bp) Length in base pairs. (Obs and Exp) Observed and expected frequencies of occurrence in library. The expected frequencies are derived from the nucleotide frequencies of each sequence in the library. Decimal scientific notation is represented by eX, where X represents the exponent. Negative decimal scientific notation is represented by e-X, where X represents the negative exponent.
