[BioC] Generating .CHP files from .CEL files

[Janet L Smith]

Thanks all - GEOArchive is indeed much better than the GEO Submission page. No need for .CHP files anymore... good.

I completely agree with Scott on this, i've tried all the GEO methods & GEOArchive is by far the easiest

If your analysis was using, say, Bioconductor tools, you never generated CHP files.  If so, it doesn't make sense for GEO to ask for them.
