There are two ways to create a new data set. You can import a data set from Excel or you can create it from scratch in OptiPath. In either case OptiPath will create a new seriation as well as a new data set. You may have as many data sets as you want but you can only work with one at a time.
To create a data set from scratch, choose Show Table from the Data Sets menu. Then place the cursor in the last (empty) row.
You must give your new data set a unique name (by default OptiPath will enter the current date and time). The other fields are optional. By default, OptiPath will make your new data set the active data set (you can override this). For more information about the data sets table and its fields, see Data Sets.
Keep in mind that any information you enter into a row of a table may not be saved or take effect until you place the cursor in another row! You will automatically be taken to the next row if you hit the Enter key after editing an entry.
If you import a data set from Excel, OptiPath will automatically create a data set and seriation for you (and artifacts and features and data).
Once you have created a new data set you will need to create artifacts and features and you will probably want to set the seriation parameters.
