So if i have understood there is no program inside or external to R that can convert a jpeg or tiff file in a txt.

so if i have agilent tiff file i need agilent program in order to obtain a txt final file and then of course i can use glad or acgh etc

best regards

Dear all
is it possible to read jpeg files from a Agilent scanner regarding CGH arrays with R....i don't know if pakages like aCGH or GLAD are able to import and translate in a txt file this kind of image.

I think that there is no software available in Bioconductor to do image analysis of orange-packed arrays.  (Someone will chime in if I am incorrect here, I am sure.)  Also, the JPEG images are likely not to be of use, anyway.  You would need the tiff images to do the image analysis.  Your best bet is to go back to the original producers of the data and ask them for the text files.
