Hello everyone, total noob on 3DSlicer here!

I have two partial cranial DICOM datasets of different length due to the unsufficient FOV of the CBCT used.  
It´s two different folders composed of 200 and 400 .dcm files each, with an overlapping segment of about 150 mm which I believe should be sufficient for proper alignment of both volumes.

Could I please get a step by step tutorial for importing both folders, aligning both volumes and finally exporting it all as either a single .dcm file or a dicom dataset?

Thanks in advance

@mikebind has a module for that:
