when i execute the command

$HHEd -A -D -T 1 -H hmm12/macros -H hmm12/hmmdefs -M hmm13 tree.hed triphones1

i have the error :

TB 350 ST_aa_2_ {}

tree based clustring

error [+2663] chkTreeobject:TB only valid for 1 mix daigonal covar models

Does this error  want to say that: i cannot work with a mixture of Gaussian in the definition of the model HMM

because  I worked with a number of Gaussian =4 .And I think it is the only point where I diviated of this tutorial.
