Raw data to your experiment is provided in an archive called a DTT. If you have a large amount of data, your DTT may be broken into several pieces with extensions like DTT, D02, D03, etc. You must have all of the files for a single set in order to read any of the data in them. If you do not have GCOS, you can still extract the individual files in these archives. First, you must rename the files. If you have only a DTT file, rename it to .ZIP. If you have several files for a single archive, rename the last file to .ZIP. That is, if you have three files in your set, rename .D03 to .ZIP. Then proceed through the remaining files - .DTT should become .Z01, .D02 should become .Z02, and so on until you have renamed all of the files. You can now open the .ZIP file with any compressed file software, and you should see the following two files for each sample:
- sample.DAT: The raw image of the microarray - sample.CEL: The probe-level data for the array. These are the files most commonly used as "raw data" by analysis packages Modified from here <http://array.mc.vanderbilt.edu/microarray/dna/targ_geno.fgsr>, found using Google.
