Thanks.

Exactly, what I need is to stop everything before the process gets on its
way, then go back, make corrections and run again. I know there are some
options to create another subdirectory (if the original does not exist) and
have an output file that I can copy to the correct path after the process
finishes, but for now I will play with your recommendation, and see how I
can progress.

It takes hour for several reasons, my slow pc, slow network, my programming
style : (, and lots of data sets to read and process. For sure, should this
gets unsustainable, I will contact the group again.

As always, the feedback is really appreciated.
