Hi all,
I have problems analyzing affymetrix data and would like to seek help from the 
1. I tried to create the design file by copying the design table from abf1 
data. In Windows version R2.8.0, the data name is "abf1", while in Unix 
R2.8.0, the data name is "abf1.raw". Why?

2. I saw probeID for abf1 data has the following format: 
"1415670_at"   "1415671_at"   "1415672_at"   "1415673_at"   "1415674_a_at". 
But the probe IDs I obtained from my data look like this:
"7892501" "7892502" "7892503" "7892504" "7892505" "7892506" "7892507"
 "7892508" "7892509" "7892510"
Is there something wrong with my data?
