hi....

is it possible to remove samples that belong to particular class ...

let me explaint it more clearly...

suppose i have four class a,b,c,d

number of records in a class:1000

number of records in b class:1000

number of records in c class:1000

number of records in d class:100

in this case for class d:100/3100 is less than .01...i want to to remove all classes that with ration less than .01...

how can i do that?

Knime should be able to handle very large datasets, it just may take longer. 

I cannot think of any other way to do what you desire.
