Hi Stefan

Many thanks for your reply.

No worries on that score, it's just [not so] simple biology.

You are correct that the image inversion is is along the x-axis. The 
colour/shading is correct.

I've not been able to fix the inversion having tried with 16m, 16m-png, 
16m-rdp, 16m-tight, 8-tight, 8 and 8-png (I hope that's enough for a 
representative sample)

What I have now found is that an earlier version of the software (EMAN2 
2.0) *does* get displayed correctly through x2go. I've narrowed this 
further to version 2.07 is OK when displayed via x2go, while version 2.1 
exhibits the inversion.
