Hi Viviana

So I have shosen to chek whether environmental factors have such impact. So I want a help on any method can allow me this explication.

Dear Hanen,
 
You can just install the new version, without uninstalling the old one. It will be like an update.
 
About PLS, it depends on your question. Are you asking on how to do a PLS with MorphoJ or the theory of it? In the first case, you should read the manual that comes in the software (in "Help"). In the second case, you might want to make more clear the aim of your study.
 
The relationship between shape and other factors can be assessed through several methods. PLS is one of them, and its aim is to study the covariation between the shape and the factor(s) without making one of them the independent variable explaining the other, but actually treating them as equals. Other options such as regression (of shape against continuous variables), MANOVA, CVA or DA can be used when the enviromental factor is represented as a grouping factor of the sample.
 
Hope this helps,
 
Viviana
