Hi everyone,
Before posting more questions, I would like to manifest my gratitude 
to Knime Community, who is providing valuable answers, tips, advices which are improving my knowledge so fast.
In this moment I am developing a PhD dissertation and Knime’s workflows are improving a lot the analytical possibilities and forthcoming achievements of the study.
As soon as my understanding of Knime get sharper, I hope to be able to contribute posting answers to questions of others as well.
Thank you very much,
Cadu
