[opendx-users] Formatting 4-vectors.

[John Vaul]

I have a field in which the positions component is a 4-vector, ie each 
data component
has associated with it four numbers in the positions component. I want 
to selected a single
component from the positions component and format it for output.
So far I have extracted the positions component from the field and used 
select to choose the item I want to output to screen, but the format 
module does not like the 4-vector. Any ideas?

Thanks
