This may be a silly question:

I am new to Agi4x44PreProcess. I have 18 samples that I used Agilent 4x44 platform. I am having problems trying to load my data to allow Agi4x44PreProcess to read it.

I was following the vignette and found that Targtes.txt was created with all your arrays as a data.frame. I have been trying to do exactly the same but have not been able to do it.

Could you please give me and advice of how to create a "targets.txt" data frame that contain all 18 microarrays, so I can used the package?

I will really appreciate your advice and sorry for the inconvinience
