There are more 3D scans than registered meshes

[experiment-designer]

Thanks for the great project and the dataset

In the downloadable registered meshes zip file (from the coma website), some folders contain only a few '.ply' registered meshes, whereas the corresponding 3D scan folder contains a few hundred scans

For example, in FaceTalk_170811_03274_TA/mouth_middle there are only 36 registered meshes.

Is this caused by some failure in the FLAME registration process?
