Software tools and services available for CIF

vcif, a CIF syntax checker
QUASAR, a CIF syntax checking and file manipulation tool (33560 bytes)
CYCLOPS2, checks apparent data names in text files against their occurrence in one or more CIF dictionaries (requires CIFtbx2)

enCIFer, from the Cambridge Crystallographic Data Centre. Graphical editor tool for single or multi-block CIFs featuring:
- Location and reporting of syntax/format violations using the current CIF core dictionary
- Correction of syntax/format violations
- Editing of existing individual data items or looped data items
- Addition of new individual data items or looped data items
- Addition of certain standard additional information via two data entry wizards:
  - Publication wizard - basic bibliographic information required by most journals and databases that accept CIF deposition documents
  - Data wizard - chemical, physical and crystallographic property information that enhances a CIF for journal or database deposition
- 3D visualisation of structure(s) in a CIF
CIFEDIT was created to view and edit CIFs, with particular emphasis on files that contain multiple blocks, which are quite important in pdCIF. For DDL 1.4 version dictionaries, CIFEDIT can use information from the dictionaries to validate CIF data items, as well as display the definitions for these items. The program is distributed as part of the NCNR CIFTOOLS and runs on Windows, MacOS (OSX) and virtually all Unix and Linux platforms.

Converting Fortran Applications for Use with CIF

CIFtbx2 Version 2.6.4 (including CYCLOPS2), a Fortran toolbox and dictionary checker capable of working with DDL1 and DDL2 compliant CIFs and dictionaries. Replaces:
- CYCLOPS, a CIF dataname checker (against the original Core CIF dictionary only)
- CIFtbx, a toolbox of Fortran routines for handling CIF data
