Dataset FAQs

What is a PIF?
PIF is short for "Physical Information File," a hierarchical file format (JSON) that is specially designed to handle materials data. Read more in our publication, review the online documentation, or check out a graphic for the hierarchy.


I uploaded a file(s), but why don't I see any PIF records?
It could be due to one of the following reasons:
  • Depending on the file type/size, it might take some time before PIFs start to appear. Check back in 5 minutes.
  • It might be the wrong file. Doesn't hurt to double check this.
  • You selected the wrong ingester. You have to choose a file format that is supported by our platform. PIFs can be directly uploaded, while select other formats require the appropriate ingester.
  • Your file has a formatting error. This is particularly true with the CSV Template Ingester, and your CSV file must conform to the documentation we specify.

Why does nothing happen when I click the "Download" button on a material's detail page?
If you are using an ad blocker, this may be causing issues. Try whitelisting https://citrination.com.


How do I get the structure of an organic molecule to render on the Citrination UI?
You have to record the SMILES string representation of the molecule as a Property, not a chemical formula or ID.


What does the "Create new version" button do?
Pressing this button will remove all PIF records from your dataset and any files that you uploaded to the dataset. It will then increase the version number that you see underneath the title by 1.
