How to get the prediction result of each decision tree in random forest?

First I built a random forest regression model
RFModel6=TreeBagger(nTree,TrainVARI,TrainYield,...
'Method','regression','OOBPredictorImportance','on', 'MinLeafSize',nLeaf);
Then how can I get the predicted value of each decision tree?

Hi hanwen,
I understand that you are trying to predict value of each decision tree from the ensemble of bagged decision trees.
You can access an individual tree by using the "Trees" property of "TreeBagger" class and predict using each individual tree.
% Example
total_trees = RFModel6.Trees % cell array of trees
predicted_data = cell(nTree, 1) % dummy output cell array
for tree=1:nTree
predicted_data{tree} = predict(total_trees{tree}, X_input);
end
Hope this helps!
