Hi Jim, Bioconductor users

thanks for the note. I tried the package and it looks good.

Unfortunately i get some error messages when analysinf the raw data.

> rawData <- ReadAffy(widget=T) # creating the affybatch from CEL files.
>
> arrayQualityMetrics(rawData, "data_raw", force= TRUE, do.logtransform= TRUE) # QC of raw data
The directory 'data_raw' has been created.
Error in seq_len(maxr) :
  argument must be coercible to non-negative integer
KernSmooth 2.23 loaded

Warning message:

do.logtransform = TRUE) :
  Could not draw spatial distribution of intensities

Error in sfs(x) :
  error in evaluating the argument 'object' in selecting a method for
function 'sfs'

But after normalizing the datausing the gcRMA algorithm I don't get
these errors.

Does anyone has an idea as to what these errors means?
I read in the mailing lists, that the spatial dist. is quite a memory
consuming procedure, but I am using a 64Bit Unix server (Ubuntu) with
48GB RAM. So I don't think that can be a problem.
Beside I don't understand the other errors.

I do get as a result a list of images as I suppose. I just want to
make sure, that these error messages have nothing to do with the
results themselves.

I hope someone can explain them in short.

Thanks

Assa
