I am trying to reanalyse some older data and would like to be able to make a custom cdf to the old Mg_u74a chip. I have the original cdf file but cant get hold of the v1 probe sequence file (if it was ever available). I am aware of all the issues with this particular chip and though that some of them could be overcome by a new cdf file if the sequence data was available. If anyone happens to have this file could you let me know. Thank you Vicky
