SF-Tool: a Crystallographic Experimental Data Validation and Conversion Tool

These crystallographic data validation tools check your model coordinates against the structure factor data.
  1. Upload your coordinate and structure factor files and indicate their file format.
  2. Choose which checks and /or utilities you would like to run.
  3. Use the Run button at the bottom to start.
Note: If you are not certain of the format/program used, select the Guess SF file format? box before running any checks. If you have refined your data using the TNT or SHELX suites, or other program not included in our drop-down list, then indicate if the data has been calculated as amplitudes (F) or intensities (I).

Input your files and select file format: (help)

Perform other checks on your data:

Fix chain_ID and alt_ID for alternate residue conformations in your coordinate file

Check if your structure factors are twinned...(requires mmCIF format)
