How can i add or set a long value to Weka Instance?
So far i only found instance.setValue() but as the attached URL stated that setValue() can only take int or double: http://weka.sourceforge.net/doc.dev/weka/core/Instance.html
Can anyone advise me please?

On page 23, it says:
So, now you have run a lot of experiments - which classifier is best? Try
cat *.out | grep -A 3 "Stratified" | grep "^Correctly"
..this should give you all cross-validated accuracies.
I suggest adding
cat *.out | grep -A 3 "training" | grep "^Correctly"
.. this should give you all training accuracies.
It's obvious once realized but it took me some time to realize.

Some feedback for the developers...
I find it impossible to read the text inside the nodes in the
Classifier Tree Visualizer since the characters are black and they're
on a dark grey background. (I'm referring to Weka 3.8.1 64-bit running
on Windows 10.) Increasing the font size to 20 points or above helps
slightly, but it's not an ideal solution. Could the background colour
be removed, please, or is there a way for the user to change it?
Dear Weka Geeks!
I am currently dealing with a multiclass problem. Among 10 class two of them are minority class and three of them are extreme minority (rare) class. I would like to investigate the potential of SMOTE in resampling and balancing class proportion. As far as I could work it out it seems that SMOTE just resample the rarest class and not the others. Am I right? Can someone hints me how can I apply it to all rare and minority classes in one data set. Ideally I would like to get something similar to what
"weka.filters.supervised.instance.Resample -B 1"
would produce but with SMOTE algorithm.
