HELP DSI Envisage Dark Save Question

[TaurusLittrowChip]

When one has the DSI Envisage software set up to save .FTS and so that it saves 4 images (LRGB) for one particular photo...when I go to combine the 4 into one color image in Photoshop or PSP do I need to subtract the dark frame from the result image or does the Envisage software take out the hot pixels in each of the LRGB images before it deposits them in the meade folder...Do I need to reach into the darks folder and use that at this point too, or is it already done?

If you had the dark subtraction box ticked when you captured the lights, and you had a temperature matched dark already captured then it is already done.
