How to convert *.BAR file output of Affymetrics TAS software?

Question

[Ashutosh]

Dear Community,

Recently I downloaded a quantile normalized BAR file from GEO for a Nucleosomal tiling array. I want to make an average plot for the genome wide nucleosomes distribution around TSS for a group of genes. Is it possible to use .bar file for genome wide profiling? How a bar file can be used to achieve this? How 2 different bar files can be compared , if they are similarly normalized?

Thanks
