NCI Thesaurus

First download the latest version of the plain text tab delimited files. This should include both the main thesaurus file and the cross mapping file

• NCI Thesaurus
  • Load the Main Flat File
  • FDA Cross Mapping File

Load the Main Flat File

Download the file

wget https://evs.nci.nih.gov/ftp1/NCI_Thesaurus/Thesaurus.FLAT.zip
unzip Thesaurus.FLAT.zip
rm Thesaurus.FLAT.zip

This is a headerless tab delimited file with the following format

• code
• concept IRI
• parents
• synonyms
• definition
• display name
• concept status
• semantic type
• concept in subset

Next use the general file loader to load the NCIt terms

node bin/load.js file ncit Thesaurus.txt

FDA Cross Mapping File

Now download the FDA cross-mapping reference file

wget https://evs.nci.nih.gov/ftp1/FDA/UNII/FDA-UNII_NCIt_Subsets.txt

Then, after you have loaded the FDA-SRS data (if you are planning to load it) load the cross-reference mapping data

node bin/load.js file ncitFdaXref FDA-UNII_NCIt_Subsets.txt
