a Number of viral copies entered in procedure.
b Tropism was inferred from the generated restriction pattern.
c Number of discordant clones between PSSM and SVM; all clones were predicted to be R5-tropic in PSSM, but either dual-tropic, X4-tropic or undetermined in SVM.
d E value obtained from the formula E = D(1-((D-1)/D)n) representing the expected number of independent clones, n = number of analyzed clones; D = number of input RNA copies. Numbers in bold italics indicate conditions where the amount of clones analyzed was greater than the expected number of individual amplifiable genomes present, suggesting resampling conditions.
e Population based phenotypic results obtained on same amplicon used for clonal analysis; D/M: dual tropic or mixed tropic virus population.
