Input Engine Recommendations
Please note the following:
- The header names in your experimental design file should follow these rules:
- The first character must be a letter (A, B, C, . . ., Z) or underscore (_).
- Subsequent characters can be letters, numeric digits (0, 1, . . ., 9), or underscores.
- Blanks cannot appear in SAS names.
- Special characters, except for the underscore, are not allowed.
- The columns of your experimental design file must be in the following order:
- A column for each experimental factor.
- A column named File that lists the file names (with or without extension) of the raw microarray data files. File extensions are recommended.
- A column named Intensity that identifies the intensity measurement variable in the raw data file.
Note: This field is required only for two-color arrays.
- Any additional columns that you want to include.
- The File column must be after the experimental factor columns but before the Intensity column (if used).
- The values in the Intensity column of your experimental design file must not be numeric strings.
- The variable name used to identify genes in the raw data files must not be a numeric string.
