Miette uses a MOR pose for the body to set the body dials, its NOT an INJ file.

MOR Pose: an abbreviation for "morph pose", this pose changes the shape of the character by adjusting the figure's built-in morph targets (for example, to make the chest smaller or the nose bigger). 

INJ Pose: an abbreviation for "injection", this pose adds morph information to a figure, usually to a previously-empty parameter dial.
