Table 1. Database auto-evaluation by assignment tests of random subsets of fibre and drug samples.

Values indicate the probabilities P of assignment (direct method) and inclusion to either groups (resampling method), as well as their standard deviations among replicate subsets (n = 10).

	Direct method	Resampling-based method
	Probability of assignment to the correct group	Probability of inclusion
		to fibres	to drugs
Fibres	1.00 ± 0.00	0.50 ± 0.03	0.0 ± 0.0
Drugs	1.00 ± 0.00	0.0 ± 0.0	0.53 ± 0.04
