Dear Pedro,
in order to calculate intensity summary for gene/exon probesets oneChannelGUI uses apt tools.
oneChannelGUI prepares a command line to be executed by the system function to run apttools.
It seems to me that the tilde in the path is probably creating some problem in the line command.
Probably you can solve the problem installing R in C:/ to avoid the tilde in the path.

However, could please open again oneChannelGUI and, in the main R windows, write the following code:

You can find me tomorrow morning on skype raffaele.calogero and we can fix the problem.
