Best Practices

Assigning ID numbers

To reduce errors and inconsistencies in RUCDR records, we highly recommend you adhere to the following best practices when assigning IDs for your study subjects

  • Use consistent separators. Separators are used within an ID to distinguish between site, family, and individual ID sections. The standard separator at RUCDR is a hyphen "-". Use the same separator, preferably a hyphen, between all ID sections. Good: 123-10-1234 / Bad: 123.10-1234
  • Use only numerals. We have observed many instances of transcription errors when IDs contain both letters and numbers, especially when RUCDR sample intake forms are handwritten. S can be mistaken for 5, I mistaken for 1, etc. For this reason, we encourage all users to use only numerals within their IDs.
  • Avoid leading zeros. Good: 123-10-1234 / Bad: 123-00010-01234

File Formats and Naming

Your AutoQC submission requires a number of different file types. When you are creating files for submission, please consider these best practices for file naming:

  • Do not include spaces or special characters (!@#$%^&*()?)
  • Include your NIMH Study ID
  • For phenotypic files, include the name or abbreviation of the clinical instrument
  • Example:
    • study999_phase1.zip
      • study999_phase1_sub.txt
      • study999_phase1_dx.txt
      • study999_phase1_id.txt
      • study999_phase1_ksads_phen.txt
      • study999_phase1_ksads_phen_dd.txt
      • study999_acknowledgement.txt
