Hi,
  STRIDE (the program that VMD uses to determine secondary structure)
most likely doesn't recognize the residue names (and/or atom names, etc) in
your structure file, so it is unable to compute the secondary structure.
You can fix this by using conventional (e.g. matching the PDB) names.

Cheers,
