text: user4209: I am analysing microarray ChIP data generated several years ago. I want to use the affy package for R. However, in order to load the CEL files and proceed with the analysis, I need the pombe annotation file which comes under the name of Sp20b_M_v04.cdf. I have looked everywhere for this file but I am unable to locate it. Is anyone in possession of this file or know where I can download it from?
  
  user3828: It looks like it's in GEO here: https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GPL10187
  There is apparently a zipped copy linked at the bottom in the supplementary files.
  When people upload a study based on an array, there is a corresponding 'platform' record where the array details should be deposited.
  Edit: you will probably need to gunzip the file first, to get it into CDF format.
