What version of the product are you using? On what operating system?
rf_ace_v1.0.3_*
all operating systems

Please provide any additional information below.
The parameter mTry should not relate to the total amount of features, but 
instead accept a positive integer with the absolute values of features to be 
selected.
As a default value there are two suggestions which performed quite nice for me 
in the past:
1 - mTRy = root(M)...where M is the total amount of features as suggested by 
Breiman
2 - mTry = log2(M)+1...as implemented in WEKA

best regards,
Berni
