since all of the data follow a Gaussian distribution. The results
were also standardized and subjected to cluster analysis followed
by multidimensional scaling analysis, using the Statistica 7.0 software

The texture means obtained by instrumental tests were compared
using variance analysis followed by the Tukey test (significant
difference when p 6 0.05), using the PASW Statistics 18
software (SPSS Inc.), since all of the data follow a Gaussian
distribution.
