Hi Gabi, Answer 1: After you have performed your CVA in MorphoJ there will be a "CVA..." under the Project Tree tab. Click on the branch of the CVA that has a notepad next to it (likely named CVA...,score"). After it is selected, go to File > Export Dataset... You will be prompted to select the data type (should say CV scores) and classifiers you want extracted with it. Select CV scores and any classifiers. You can name your file and add a .csv instead of .txt so you can import it into Excel. For this step, I use OpenOffice because it handles tab delineated files better.
Answer 2:For discriminant function among all of your sites, you will need to export your shape data from morphoJ and do it in a different statistical program. Which data you plan to use will be up to your specific research question, but you can export the Procrustes coordinates and centroid size by again going to the Project Tree tab. After you have done your Procrustes Fit, go to the Project Tree and select the very first branch (should be the name of your dataset). Again go to File > Export Dataset and select the data and classifiers you want. If you wanted to use PC scores from the Procrustes coordinates, you have to run the PC first and then go back to the Project Tree, click on the PC scores branch and back to Export Dataset. Doing your DFA outside of MorphoJ will allow you for stepwise selection of variables, which may or may not be applicable to you.
