Export data underlying dwell time analysis may not have a normal distribution; consequently, an MLE analysis was performed (Kay, 1993). The differences between dwell times in REF and mex67-5 strains were tested using the distribution independent Wilcoxon rank-sum test and were found to be significant at P < 0.05 for the transition and cytoplasmic docking states. For more details and a discussion of error measurements, see the Materials and methods section Statistical analyses.
