You have not imported a group but a single Field, so you can not
use the Select module after Import.  Your data is probably importing
correctly as currently described and you should try the Print
(options="rd") to display how the data are stored within the DX data
model. You will see a single Field with 3 components (data, positions,
box). The data is just the atom labels.

I am still wondering what is in the 32 line header that you are ignoring.
I am guessing it contains the atom size, bond length, etc. that you really
want to display.
