I have a plain text file with 12,000 probe id names from an affymetrix chip.

Can someone please review the details of how to output out a plain text file
with the GENE SYMBOLS

I am using AffyNet from Affymetrix.net and going to Batch Query in the
Expression section where it says
"Retrieve annotation for a probe list", where I search for "probe set id"
and view the list with "gene list". Is this
correct?

Some problems encountered so far:

1) affynet tells me it can only export 3000 genes
2) afffynet changes the order of the outputted genes by putting probe ids
that start with AFFY last. (they are in fact first)
2) affynet exports out more information than I need, I just need the gene
symbol.

Can someone please lead me through the procedure to output out a simple text
file of gene symbol?

thank you in advance
