Hi Henrik,
Lowering memory helped - it's drinks on me when we meet.
It has been running for approximately 7 days now ("ETA for unit type
'expression': 20140320 23:20:26"). With the updated affxparser can I speed
it up by increasing the memory burden? The current memory allocation is
approxima
Did lowering "memory/ram" solve your problem?
Also, an updated version of affxparser that no longer should overflow
by the integer multiplication is available (on Bioconductor).
Cheers,
Henrik

Congratulations Damian,
I think your the first one to hit a limit of the Aroma Framework
(remind me to by you a drink whenever you see me in person).
I narrowed it down to the affxparser(*) package and I'll investigate
further on how to fix this. It should not occur and I'm confident
that it can
Hi Henrik,
Thank you, that was helpful.
I run to another problem though. I am trying to perform ExonRmaPlm(csQN,
merge=TRUE) but this produces a following error:

Thanks, that helped a lot. It took me less than 3 hours to perform the
background correction.
Now I'm wondering if for the next step, quantile normalization, I could do
a similar trick. Is there a way to precompute the target empirical
distribution based on all arrays and then do the normalizat

Hi,
I'm processing around 5500 affymetrix exon arrays.
The RmaBackgroundCorrection() is pretty slow, 1-2 minutes/array. I played
with setOption(aromaSettings, "memory/ram", X) and increased X up to 100
but it didn't have any effect on this stage of analysis.
Any way to speed the process up?
