Need help reading this data

[Celestic]

Hi I am a computer science graduate student and need help reading some data for this bioinformatics research I am helping out on. I have a few hundred text files containing the following sample information:

Geno SNP_A-8343733 NA
Geno SNP_A-8338245 1
Geno SNP_A-8338251 NA
Geno SNP_A-8338258 0
Geno SNP_A-8344803 1
Geno SNP_A-8349310 1

I want to know how to read this data and what kind of data is this? I am new to Biology and Bioinformatics in general so any help would be greatly appreciated!

check out "affymetrix array snp calling" output formats and codes

SNP_A* are snp ids (which map to dbSNPS's rsIDS)

The code is probably ...
0=AA (homozygous for the reference allele)
1=AB (heterozybous)
2=BB (homozygous for the alternative allele)

but make sure.

Okay thank you. I found out that it is affymetrix array snp calling 6.0 but not sure what I can do with this data exactly?
