[cmview-users] Problem running various pdb files

Thanks Jose,

It is a weird problem of editor!! Everytime I add chainA (manually), every 6 space (in the columns) change to a tab. Probably, cmview cannot translate it back to space, so the formatting error occurs. 
For the moment, I don't have any problem any more.

Cheers
Maryam

To be honest I can't see why it goes wrong there. If you can send me the PDB file I could have a look and maybe find out what's happening exactly.

Cheers

Jose

          the problem in running the cmview for my pdb files is still
          persisting. How can I generate a pdb file that cmview likes? I
          changed the header to the one that was working, and I added
          chainA to the column 22. When I wanted to load I still got two
          options for chain (A & NULL (attached as NULL). I solved
          that by adding numbers from the main pdb file.
>Then, I loaded again and I got wrong number format error. Could you please let me know how can I solve it? How can I have the right format?

I had done it once and it was working but now I can't make the same configure file again! Could you give me a hint? I will appreciate it a lot? Or is it a bug that dssp is not running, since I read something about it while I was looking through the problem.

So I've managed to track it down to a problem with the chain code used for the ATOM lines (your file has an empty chain code) and the one used for the SEQRES lines (chain code A). It is a bug in CMView: it does not match the 2 sequences up and then tries to guess a sequence from the residue numbers in ATOM lines, instead of using the SEQRES one.

                                                    code A for your ATOM
                                                    lines (replacing the
                                                    blank in column 22),
                                                    then you get the
                                                    correct contact map
                                                    displayed. Also I've
                                                    noticed that your
                                                    coordinates end at
                                                    TYR 226, but the
                                                    SEQRES sequence has
                                                    a few more residues.
                                                    It would be good if
                                                    you also removed
                                                    those from SEQRES so
                                                    that you don't have
                                                    a few trailing
                                                    unobserved (empty
                                                    coordinates)
                                                    residues.
