WebThe accuracy of PSI-BLAST statistics might lead us to speculate that the lambdas for gapped alignments are a function only of the scale of the substitution matrix and the gap costs. Unfortunately, this is not the case, as an examination of Table 3 demonstrates. It appears that the effect of specific gap costs on lambda is a function at least of ...
