Hello!  
I am working with sets of left and right long bones from the same specimens in MALPACA. I am trying to determine if I should build my consensus atlas from (A) just the left side or (B) left side and mirrored right side models.  
An additional consideration is that my sample is from subjects that were scanned from medical necessity. This means that some specimens may have abnormal morphology on one side or the other.

Just one side and use it, reflect the other to that side. Avoid abnormal samples in the template reconstruction.
