Hello,

I am using the oligo package to work with tiling arrays.

I was wondering if there is a way to either:

1.  See how the pmindex function in oligo is calculating the indices?
or
2.  Obtain the actual x,y coordinates for each probe?

I found the functions indices2xy and xy2indices in the affy package, but can't seem to find an equivalent function in oligo.

Any advise would be greatly appreciated.  My session info is below, in case it is helpful.

Thanks!
