hi, i kept having the error message about the data

The leaf of the tree:myTree labeled Node1 had no match in the data. Please make sure that all leaf names correspond to a sequence name in the data file.

my code:
Tree myTree = (Or((Mc,Gb)(Hm(Gr(Ch,Bo)))));

my data is in .txt file, the leaf names are Or, Mc,etc

Do I need any specific struture of the data?can it be .txt? or must be .seq?

Should the species name start with #?seperate with the ACGT by space?

Thank you so much

Hi, Sergei

I changed the tree defined to

(Or,((Mc,Gb),(Hm,(Gr,(Ch,Bo)))))

Error:The number of tree tips in myTree (7) is not equal to the number of species in the data filter associated with the tree (0).

the data file is 7 species, start with species name, then sequence. does the data file need a special format?

Thanks
