How to visualize tracking data imported from Optitrack Motive as an fbx file?

We are performing Motion capture recording using Optitrack Motive. I extracted this motion capture data from Motive as an fbx file. Now, this fbx file contains only the tracking data (just co-ordinates) and does not have a model. I imported this fbx file into Unity as an asset. I need to able to apply this motion capture (fbx file) onto a character rig in Unity. I tried draggin and dropping the fbx file into the character rig ('Man in Suit') but ti doesn't seem to work. I need help in applying motion capture data onto a character in Unity.
