Collated project workbookOverview• The collated project workbook is the primary data object on which futureanalyses are run• The collated project workbook is located inside the project folder, , which bydefault is located inside the folder where the original input data is located.• The project folder may also contain some other folders: Binary<strong>Data</strong>,Annotations, Output, , and Genelists.• The Binary<strong>Data</strong> and Annotations folders should NOT be altered byusers. These are used for internal purposes.• The Output folder will contain the output of all subsequent analyses.• A Genelists folder may also be created, and may contain genelists to beused for subset analyses.54
The collated project workbook• This is the primary data object on which future analyses are run.• Contains three primary worksheets:1. Experiment descriptors (may edit this to specify analyses)2. Gene identifiers3. Filtered log ratio (or Filtered log intensity)• Additional results worksheets which may be automatically added:1. Gene annotations (obtained by running the menu item:Utilities Annotate data Import Affymetrix or SOURCE annotations)2. Scatterplot results3. Cluster analysis results55
