Hi Michael,
if I understood correctly your question, I would do the following:
- Average replicates by specimen (I assume you did this to reduce
measurement error so you wanna take averages for each observation)
using the "Average observation by..." function
- Use the DFA module to perform a discriminant analysis using a
classifier for dataset as grouping variable. One of the graphs is "a
diagram with the shape difference between the two group means" (quoted
from MorphoJ user guide)
Again, not sure if I interpreted correctly your question...
I hope this helps,
Carmelo

Hi All,
I am running MorphoJ on Mac OSX. I am looking at morhological variation
between two datasets. In each dataset, each specimen has four replicates. I
combined the datasets, made classifier files and ran the Procrustes fit and
generated the covariance matrix. How then do I make a vector diagram/warp
grid that visualizes shape change between the average shape of the two
datasets? Thanks in advance for your help.
Mike
