Where your scorer produces files that are supported by CARDS all you need to do is import the event.
From the main screen [Event F2] on the [1Start] tab click 'Import an event' and click [Import] . The quick key command is [Ctrl-I].
You will be shown a dialogue to open the event session file produced by your scorer. The file type normally is .csv, for example "myevent.csv".
[Open] the selected file and you are then asked to "save" the event. This is the CARDS event file and nothing to do with the original scorer's event. All the event detials, scores and names are extracted from the scorer's file. Also the ratings' impacts have been calculated so you can select the report button to show the impact results to the players.
