[BioC] [R] make.cdf.package: Error: cannot allocate vector of size 1 Kb

[James MacDonald]

This problem may well be due to the repeated R_alloc calls, and might be fixable by refactoring the code, but I am not sure that is the answer here. This package is designed for the 3' biased arrays (and works well enough for them), and isn't intended to be used for the newer random primer arrays. The makecdfenv/affy packages have been supplanted by the pdInfoBuilder/oligo packages for the newer generation of arrays.

Crispin Miller's group was able to get makecdfenv to work by stripping out the background probes first, and have cdf packages available on their website if the end user insists on using affy for this array:

http://xmap.picr.man.ac.uk/download

which by the way appears to be down now.

Anyway, the supported methods of analyzing these chip types are listed in the workflows page

http://www.bioconductor.org/docs/workflows/oligoarrays/

and you will note that makecdfenv/affy is not one of them.

Best,

Jim

For me this tops out at about 13 gigs.

The reason is I think in the C-level implementation details. R_alloc is
called repeatedly during file parsing, where likely the author intends
to Calloc / Free.
