[i] (Cutoff) parameter in blast algorithm that corresponds to strictness of search; the smaller the value, the stricter the search (less matches). (No. of families) the total number of families (>1 gene per family) in the data set. (Genes in families) total number of genes in all families. Mean, median, maximum, and skewness are computed for family sizes (number of genes).
