Dear all,  
I downloaded the slicer morph extension to use the \_rec.log file for the reconstruction.  
however, the input and output option did not show up on my program and I was unable to use the log file.  
I tried redownloading the extension as well, but it did not worked.  
Can anyone explane to me why this may have happened?

Any advice would be appreciated.  
Thanks.

I cannot reproduce this with today’s preview, all three subcategories are there. How did you install the SlicerMorph extension?  
Try uninstalling and reinstalling the extension and see if that fixes?
