Thank you Carmelo and David for your answers.
I ran the outliers test as recommended by David and then copied the Mahalanobis
distance (squared, which are easy enough to convert back) along with the
individuals ID and pasted them directly in to excel.

I am currently trying to test the degree of difference (measured as a
Mahalanobis distance) between two groups.
To give some background I have 2 groups of fish that differ in their life
history strategy (groups A and B), these two groups have then been exposed to
different conditions to induce
Hi Alex,
If you want to remove the effect of size on shape that is caused by ontogenetic
allometry (differences in shape due to age/size per-say) you can regress the
Procrustes coordinates of your samples on the centroid size and then use the
residuals.
Hope this helps,
Oliver Hooker
