Here is my "success-story" on the conversion of CIF-files to PDB files.
According to your suggestions I tried the following:
I downloaded PLATON
- conversion of the first CIF-file caused the program to crash
- conversion of the second CIF-file produced a useful PDB file!!
=> success rate 50%
I tried to use "libcheck"
- there is a typo in the manual _FILE_OUT and _FILE_O are mixed up
- the warning message was:
WARNING : residue: C00 1 chain:AA - not found in the library
WARNING: can't find atomic scatt.factors for :
default symbol is "N "
- no PDB file was produced
=> success rate 0%
Pete Duntan suggested "Rasmol will read the small molecule cif file and
output a pdb file."
- Rasmol was able to read one of my three CIF-files
- It did output a PDB-file but the coordinates were completely screwed up
=> success rate ~10%
BABEL cannot read CIF-format (at least not the version we have installed)
As I reported before:
- CIFTr (from http://pdb.rutgers.edu/mmcif/). Gives a run time error.
- CIF2PDB (from http://www.bernstein-plus-sons.com/software/cif2pdb/DISCUSS.cif2pdb.html)
doesn't compile properly - at least in my hands.
I hardly can believe. Is CIF-format even worse than any language
produced in Babel
that noone can understand. Any hints and suggestions are still appreciated!
Pete
