Dears, I removed ape 4.1 and install 4.0 version and the problem with my tree is gone. I can extract clade even my tree having singletons. But the problem still occur in example tree, with new error message. With this tree:

((((A_1,A_2,)A,(B1,B2,B3)B)C,((((D1))),(E1,E2)E)D),(F1)F)R; or (((((A_1,A_2,)A,(B1,B2,B3)B)C,(D1,(E1,E2)E)D),(F1)F)G)R; I have this new error: Error in phy$edge[, 2] : incorrect number of dimensions And with this tree: ((((((A_1,A_2,)A,(B1,B2,B3)B)C)ABC,((D1,(E1,E2)E)D))DE,(F1)F)G)R; rsession running infinitely. I need force stop. Best regards, Mario On 1 June 2017 at 16:13, Mario José Marques-Azevedo <mariojm...@gmail.com> wrote: > Dear Eliot, > > Thank you for your answer!
