Re: [opendx-users] Formatting 4-vectors.

[David Thompson]

Are you asking to select a single element from the 4-vector to send 
to Format? If so, use compute with a statement like a.n where n is 
the number of the element you want -- for example a.0 will give you 
the first element in the vector.

David
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
