Hello,
I am using R 2.10.0. The sessionInfo data is below at the end of this
message. I am using Ubuntu 10.04.
I am attempting to re-annotate custom Affy PM-only chip using a new
gene-annotation for my prokaryotic genome. I have gotten stuck on
altcdfenvs, however.
What I have done so far:
1. Changed the makeProbePackage code to not require MM probe data
2. Created a probe package from my probe_tab file with makeProbePackage (for
some reason 4800 probes did not match between the probe_tab file and the
Affy-supplied .CDF file)
3. Installed the new probe package with help from James MacDonald
4. Started following the altcdfenvs documentation....selected the
constituting elemets, matched the probes.... Everything went smoothly until
match analysis:
> alt.cdf <- buildCdfEnv.biostrings(m, nrow.chip = 330, ncol.chip = 330)
Warning message:
In buildCdfEnv.biostrings(m, nrow.chip = 330, ncol.chip = 330) :
Check index for MM probes.
I assumed that the geometry of my chip is 330 x 330, as these are the
largest X and Y values in the original probe_tab file.
I don't know why i got the MM probes error.
Also, I find that the altcdfenvs documentation becomes much less
understandable from this point on.....I don't know what to do with
validAffyBatch(abatch, alt.cdf), etc....where does abatch come from?
If you can point me to any informative discussions on how to proceed, I'd
really appreciate it. Sorry for the newbie questions.
