Now that the morph channels have been created via the DzCreateExPFiles-M4.comand, we can now inject the morphs into M4.  Navigate over to where your morphs reside in the Pose subfolder.  I don't know how your Pose folder is set up, but I can show you mine. 

In the attached image, you can see that I have all of the morph injections in 1 subfolder.  From here, simply double click on the morphs you want to add and Poser will inject them into the figure.

You could inject all of the morphs and then save the resulting .cr2, but I don't recommend that.  The figure becomes quite heavy and the odds of you using most of the morphs is nil.  I would recommend loading the Base morphs (INJ Base M4) and the ++ morphs (INJ Morphs++ M4)  These are what are used by 90+% of the figure character creators.

If you have any other questions, fire away.
