[BioC] Matchprobe package

[Wenqiong Chen]

Hi, Nathan:
I was the one who posted the message long time ago which you quoted in
your message. This is the command I tried which worked eventually, which
is, believe or not, much straightforward.
> makeProbePackage("disdiv712a",
datafile="diS_div712a_probeSequenceFile.txt", maintainer = "Joan Chen
<jchen at diversa.com>", version    = "0.0.1", force=TRUE)

Where you only need to supply unzipped txt file of your probe tab file.
You do need to supply the column names in this txt file.
Hope this also works for you!
Best,

Dear Nathan,

please excuse the delayed reply. The answer is yes. You can import a
wide variety of probe-description files by adapting the function which
is given to the  'makeProbePackage' function by the 'importfun' 
parameter. Have a look at the default 'getProbeDataAffy', this is a
function that works for the "normal" probe_tab files. Its (simple)
commented source code is available through the source packages
(.tar.gz). I recommend using this as a template and adapting it.

You can use "options(error=recover)" and the debugging browser of R to
see what exactly is going wrong with your file. I am afraid it is
difficult to tell for me from  the information you provide, and I
suppose with a little bit of basic R knowledge (maybe ask a local guru)
you should be able to trace this down.

  Best wishes
  Wolfgang
