Line chart of the average TC respect to different e -value thresholds on UniRef50-TM database. The number of homologues is counted by summing all homologues found in eight families and plotted in log10 scale. The standard error of TC score cross eight families is the range of dash line. SP is skipped due to minor change respect to different e-value thresholds.
