Dear Virginia,
I am the maintainer of oneChannelGUI.
oneChannelGUI summarize intensities using APT tools.
One of the important points, indicated in the installation instructions, is that R folder and your data folder
are without "space in the path", which are creating problems when the command for APT tool is executed by oneChannelGUI.

Please check if you have space in the above indicated paths and be sure that the working folder of oneChannelGUI is the one where the cel files are located.

If you are still having troubles please load oneChannelGUI and execute in the main R windows the following commands and send their output to me together with you target file:

Dear list,

This is my first experience working on microarray data. I am trying to
analyze Human Gene 1.0 ST microarray data with oneChannelGUI. However,
this seems to be not a straightforward task. I have been playing
around with data and the application and I am a little bit confused
and without any result yet!

First, I installed all the packages and then, followed the user guide
When I select "GENE 1.0 ST ARRAYS: probe sets summary from Affymetrix
APT" option to perform a new analysis, it asks me if I want to use APT
for gene/exon summaries. I click "yes" and chose the organisms (in my
case, Hs). Next, I select the working directory, the target file and
answer "no" to the question "are you using genechips version 1.1?".
Finally, as APT tool intensity summary option, I select "rma-sketch".
Inmmediatly, I get a series of error messages (see below).

I really do not know what is happening here. I would like to make the
background correction, normalization and summarization, and also run
On the other hand, I can load a normalized tab delimited data set and
apply some functions on it, but I do not know how to include the
annotations into the final list of differential expressed genes (top
anybody has a suggestion about what is happening here and how could I
solve it?
I would appreciate your help.

Best regards and thank you in advance for your attention.
