Dear Dr. Fyllas
Thank you very much for providing a revised version of your manuscript addressing the reviewers' comments. The manuscript can now be accepted for publication subject to two minor technical corrections.
First, on lines 237-238 of the revised version, you mention that the sampling of the trait quartets is done without the assumption of an underlying statistical distribution. However, a few lines above (line 229) you mention the sampling was done from an uniform distribution. Can you please clarify in the text this apparent contradiction?
Second, please define the abbreviations presented in Table 1.
Once these two issues are addressed, the manuscript will be ready for publication.
Thanks for your submission to GMD.
Carlos A. Sierra
