[aspect-devel] Plate motion reconstrucion - Layered rheology

Hi Eleonora,

Could you elaborate on that? What is the error message that you see if 
you follow the instructions that Anne send?

If this continues to fail that might mean GPlates has again changed its 
data format (they did that once in the past, and we currently support 
both formats). If Anne's suggestions do not help, could you send me 
which version of ASPECT and GPlates you are using (and ideally also the 
plate reconstruction you used if that is possible, though better send 
that in a private email off the mailing list)? Then I can try to 
reproduce the issue and look for a fix.

Best,

Rene
