Select attributes subset doesn't showing attributes

Try putting a break point before execution of the that select attributes elements. Then, different variables will show up at that break point, and you can select the subset of attributes. You can save it and remove the breakpoint.

Ok, but why I cannot see variables in select attribute operator? On other machine (64bit version) it is not a problem. Do you see all your variables in that specific operator and what version of  RapidMiner you use?

I do not know why select attributes element does not show attributes in some cases - it usually happens if that element is deep inside the program flow. Following is the procedure for attributes to appear in select attributes elements, if such a thing happens

1) Put a break point by right clicking on the select attributes element, such that the program stops before execute that element
2) Run the program
3) Program will stop at the break point and show you the attributes that you can select. Select attributes you want to, save the program and start it again.

Hi,

if you are sure that the attributes are present in your data, you can also enter them manually in the select subset dialog. Just enter type them into the right edit field and press the green plus "+" right of it.

Best,
Marius
