Hi Mahendra,<br>
Probably the format is slightly wrong for the lines with the calcium ion coordinates. For example, the name CA for the calcium ion should *not* line up with the name CA in the protein alpha-carbon lines.<br>
<br>
In the ATOM and HETATM lines of PDB files,<br>
<<a href="http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/tutorials/pdbintro.html#coords" target="_blank">http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/tutorials/pdbintro.html#coords</a>><br>
<br>
...the ion name CA should be in columns 13-14, whereas the alpha-carbon name CA should be in columns 14-15.<br>
<br>
Misalignment of ion names is a common problem with the output of many programs.<br>

When I loaded it in chimera, the protein structure looks fine but two calcium atoms that the protein binds could not be visualised, although the pdb file-format looks good.<br>
