Hi Yu (posting to the board for reference) To get the cif files is quite easy E.g. at http://pdb.org/pdb/explore/explore.do?structureId=2v5p you'd go to the lower right part and get the structure factors from the "experimental details" box. At http://pdbe.org/2v5p you would click the "experimental data" link to be able to download the file.
If you are using phenix (it looks like you are) then phenix.fetch_pdb is much easier to use! There's also a phenix bulletin board you should use for questions relating to phenix ( http://www.phenix-online.org/mailman/listinfo/phenixbb) Also, if you have a recent version of COOT, then it can calculate a map for you on-the-fly through the "extensions" -> "PDBe" menu. Be aware that the version of COOT distributed with CCP4 does not work, but the versions from http://www2.mrc-lmb.cam.ac.uk/Personal/pemsley/coot/devel/build-info.html works. (The problem seem to be a change in the way PDBe was storing their files) Best regards, Folmer 2014-08-21 9:53 GMT+02:00 Yamei Yu <[email protected]>: > Hi all, > > I download the mmcif file from PDB entry 2V5P, and then I use > phenix.cif_as_mtz > (or cif2mtz ) to try to convert the cid file to mtz file but I got the > following error message:” Sorry: Please specify one reflection cif file.” I > also tried several other PDB entries but got the same error message.
