Re: [Swarm-Support] Problems creating input object from .scm

[David Camacho Trujillo]

Many thanks for fast the response.
Well, I am sure that the serialization part is some thing I want to implement
soon or late in my model, but by now it is not the point.
Sorry, seems to me that I explain my self wrong. 
My problem is not related to any Output, but the other way around, with the
“Input”. (I just called here so a class that import data form a .txt table)
The mention of the Output was just trying to explain, in my concepts (very
likely wrong) the “position” on the Hierarchy of this “Input” class I create.

I will try in other words to explain my self better. 
For my problem, apart from some parameters, my model has to:
Open a file (HERE is the problem, but JUST when I try to utilize replicator2)
Read the data into the file (a table)
Perform an interpolation of that data
stored the interpolated data into an object
be able to pass this last interpolated data to the agents created by the
“modelSwarm” class.

And every thing goes fine. It is just that when trying to run this (changing
systematically some parameters) utilizing replicator2, that so called by me
“Input” class, could not open the file and the program exit.
(I hope this time it is more clear my simple problem)
many thanks in advance!
David
