The PDB offers several ways to locate experimental data files for
structure entries. The SearchFields interface offers an option to
narrow a search to only include entries that have experimental data
(X-ray structure factors or NMR restraints) available. This option
can be activated by selecting "Experimental Data Availability" from
the custom options at the bottom of the SearchFields page. To further
narrow the search to only structure factors or only constraint data,
select the preferred experimental method from the pull down menu in
the "Exp. Technique" field. Information about this and other options
available on the SearchFields interface can be found on the
SearchFields help page.
Experimental data files can be downloaded from the Structure Explorer
page, if the experimental data file is available for that structure.
Click on the "Structure Factors" or "NMR Restraints" link on the left
side of the page to access the experimental data file.
Experimental data files are also available for downloading from the
RCSB PDB FTP site. Directories for either X-ray structure factors or
NMR restraints can be found at
subdivided by the second and third character of their PDB IDs at
data files for structures that have been removed from the archive
can be found at ftp://ftp.rcsb.org/pub/pdb/data/structures/obsolete/.
