Dear Emma, The problem as it turns out was that I was using Stereoscope to digitize my specimens. Stereoscope digitization differs a bit from geomorph and the coordinate organization caused the inflection of the points in geomorph. However, Aaron was able to add code to Stereomorph that rotated the coordinates properly that allowed me to then analyze in geomorph. Thanks for your email.

When this option is TRUE, the shape coordinates are aligned by their principal axes rather than how the configuration was digitized- this is for visualisation and isn't changing the shape infomration in any way. Might this be the source of your concern?

For a newly digitized dataset the plot of the aligned landmarks of all specimens is horizontally inverted This is not the case for an older dataset also digitized using TPSDig. This must be a common issue but am unable to resolve. Any suggestions?
