Dear Bioconductors,
I try to use marrayQualityPlots from the arrayQuality package on a raw
data object generated by limma. I get an error message that I do not
understand (see below).
My installation is the following:
Mac OS 10.2.8
Darwin 6.8
R 2.0.1
arrayQuality 1.0.7
hexbin 1.0.10
Any hint would be highly appreciated. Thanks!
Georg
here is the error message:

Dear Georg,
It looks like maQualityPlots is crashing in one the internal functions
plotting the density of your data, but I never saw this error before.
Could send me the original image processing file and the command you
used to generate your RGList (or your RG object if you don't have the
file) so that I can find what is causing this problem?
Thank you very much for your help,
Agnes

Dear Agnes,
thanks for your offer to help. It might have been a problem with
memory, since today i tried it with data from only two hybridisations
(instead of twelve) and it worked, although it took a long computation
time. I will let you know when I found out more.
Now i have a different problem: I do not know how to do with the png
file of the diagnostic plots (in fact, I do not know much about
graphics at all). The plots and the characters are too small to be
readable and magnifying does not help. Unfortunately, postscript does
not work as an output file, it gives me the error message:
> maQualityPlots(RG, DEBUG=TRUE, dev="postscript")
[1] "function starting"
[1] 17328 2
[1] "Re-evaluate Weight"
check Control color code 2 3 4 5
[1] "Set up data and normalization"
[1] "Reading normalization parameters"
list()
Using normalization method: p
[1] "Name the output file"
[1] "hps-d4-cg-p4-slide16-25"
[1] "Name of output device"
[1] "diagPlot.hps-d4-cg-p4-slide16-25.ps"
[1] "start layout"
Error in ifelse(onefile, "Rplots.ps", "Rplot%03d.ps") :
Object "onefile" not found
Now my question is: what is wrong with postscript here? Or
alternatively, is there a way to produce larger png files with larger,
readable characters and plots?
Thanks a lot,
Georg

Hi Georg,
If maQualityPlots is too slow, you can try to speed up the process by
changing the default normalization method to global median or loess.
To do so, you can try:
maQualityPlots(RG, norm="m")
The diagnostic plot from arrayQuality is pretty complex to generate,
and
unfortunately making the font bigger requires a lot of modifications.
The resulting plot should be of size 1600x1200. You should also be
able
to zoom in the png image using any image viewer until the plots and
the
characters are big enough. If not, could you please send me your file
so
that I can investigate what causes this problem?
I will try to fix the postscript extension problem as soon as
possible.
Regards,
Agnes
