Thanks Miguel and Angel!

Hello,

I am working with PDB consensus coordinates derived from several
structures and I'm not able to view the molecule as backbone, wireframe,
etc. in Jmol. I only get atoms as unconnected spots. I have no problem
with Rasmol or Chime.
Any idea? I send a PDB test file.

Your file format is incorrect.

In the case of N, C, and O atoms you have put the element symbol in the
column reserved for the the alphabetic remoteness indicator and have left
the element symbol blank.

You have:

ATOM      1   N  GLY     1       4.794  -0.966  -4.193  1.00 99.00
ATOM      2  CA  GLY     1       3.792   0.001  -4.433  1.00 99.00
ATOM      3   C  GLY     1       2.880   0.006  -3.283  1.00 99.00
ATOM      4   O  GLY     1       2.357  -1.002  -2.940  1.00 99.00

You need:

ATOM      1  N   GLY     1       4.794  -0.966  -4.193  1.00 99.00
ATOM      2  CA  GLY     1       3.792   0.001  -4.433  1.00 99.00
ATOM      3  C   GLY     1       2.880   0.006  -3.283  1.00 99.00
ATOM      4  O   GLY     1       2.357  -1.002  -2.940  1.00 99.00

I have attached 'repaired.pdb'

In addition, filling in columns 77 & 78 with the element symobl is
recommended.

An excerpt from the PDB specification is below.

* Six characters (columns) are reserved for atom names, assigned as follows.

   COLUMN     VALUE
   -----------------------------------------------------------------------
   13 - 14    Chemical symbol - right justified, except for hydrogen atoms
   15         Remoteness indicator (alphabetic)

   16         Branch designator (numeric)

   77 - 78    Element symbol, right-justified
