Hello all, Does anybody happen to have code to convert a flat file of probe X and Y positions, into a CDF file in the classical text format? The input file would look like the one I've copied below. The result would look like one that could be processed by makecdfenv. In case you wonder, I need this format to submit my CDFs to the GEO database. It would be extremely helpful. Thanks in advance!

writeCDF in affxparser. You need more information than you have provided below. The input structure to that function is exactly what you get from using readCdf on a CDF file, so I suggest studying that outut a bit.
