Dear All, On behalf of the Development Team, I’m proud to present to you the FinShape web App: http://finshape.morteo.mx <http://finshape.morteo.mx/> This is the evolution of the FinShape v0.1 Desktop App, that appeared on the research paper by "Morteo et al. (2017), entitled “Phenotypic variation in dorsal fin morphology of coastal bottlenose dolphins (Tursiops truncatus) off Mexico": https://peerj.com/articles/3415/ <https://peerj.com/articles/3415/> Based on the Weller (1998) method, it uses semi-automatic standardized and very precise (pixel) measurements on photographs to compute 2D ratios and fin’s surface area, which may be potentially useful to distinguish stocks and populations. Please give it a try and let us know what you think. The User Guide should be sufficient to operate the App; but if not, you may find details on the image selection criteria, and the full measuring process in the MSc thesis by Morteo (2004) (pages 20-24): https://www.researchgate.net/publication/200836165_Dorsal_fin_morphological_... <https://www.researchgate.net/publication/200836165_Dorsal_fin_morphological_differentiation_in_bottlenose_dolphins_Tursiops_truncatus_along_Mexican_coasts_an_adaptive_approach> If you find any issues, we’ll be more than glad to help you in any way we can to make the best use for this App. We hope you enjoy it!
