Create a CSV data dictionary using the CSV_dd_template. You can create either:
a. One data dictionary for each data file or
b. One data dictionary representing all data files in your dataset -
See the CSV_dd_quick_guide for more details about completing the template
-
Enter a new row in the data dictionary for each column/row name in your data matrix
a. Use "*" wildcard when the description applies to multiple column/row names
b. For example - if the same description applies to all spectra data column names in the data file(s)
i. one row in the data dictionary can refer to "wave_*" and this definition will be understood to apply to multiple column names within a data sheet -

Save the CSV_dd template following the CSV Reporting Format guidance with the filename "dd.csv" or "*_dd.csv". Alternatively you may choose to name you data dictionary:
a. With the same name as the associated data file, but include '_dd.csv' at the end of the file name
b. Create a unique filename for your data dictionary
c. Incorporate a wildcard into the filename if data dictionary applies to multiple data files (for example - "soil_cores_*_dd.csv")
