enter image description here.

you can set Discretize filter to use 2 bins.

Set makeBinary, useEqualFrequency to True and desiredWeightOfInstancesPerInterval accordingly

You need to set attribute indices accordingly. For example below command only change index 2. weka.filters.unsupervised.attribute.NumericToBinary -R 2

  1. Click to empty place near to NumericToBinary
  2. Click to AttributeIndices empty place and write your attribute value.

You Didn't mentioned Sufficient details in question. But in any kind of relational databases you can access any cell just like accessing cell in 2d Array.You have to mention exact location(indices) to do that.
