I don't think you need special software to do a sequential Bonferroni correction -- I guess it's easier to do that by hand (and maybe a calculator) or in a spreadsheet. For a recipe, see http://privatewww.essex.ac.uk/~scholp/bonferroni.htm (or just about any basis stats book) I hope this helps. Best wishes, Chris On 10/29/2010 12:44 PM, morphmet wrote:

Can somebody please help? I used the permutation test in MorphoJ for pairwise comparisons of Procrustes distances between group means (6 groups, 10 000 iterations). And the differences were (as I've expected) statistically significant. But now I am wondering if I have to correct the p values. Or are they already corrected? If they are not then I would like to perform the sequential Bonferroni. But how? Is there a user-friendly software that would do this for me? Any suggestions? Thank you! Tina Klenovšek Slovenia
