Dear BioC,

    I'm trying to learn about Affymetrix Tiling Arrays and I have a few
questions regarding the array design of the Yeast Tiling array

1. One of the sequences is labeled as "chloroplast" what is this sequence and
what is its purpose?

2. Some chromosomes are listed under 2 sequence sets and the PM Position numbers
do not match up - there are gaps in the sequence. Why?

3. What is the purpose of the gcBinXX sequences? Are they control sequences? How
are they organized?

4. What are the r2_ and X_ sequences?

Any kind of help would be appreciated.
