To create a seriation, choose Show Table from the Seriations 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 - you can override this). OptiPath also enters the date and time the seriation is created (which you can't override) and a few other values which you can override. By default, OptiPath will make your new seriation the active seriation (you can override this). For more information about the seriations table and its fields, see Seriations.
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.
Once you have created a new seriation you will need to create artifacts and features.
