Audit Data References
Scan all notebooks for data file references and verify they exist on disk.
Steps
-
Scan all
.ipynbfiles innotebooks/for data loading patterns:- Python:
pd.read_csv(...),pd.read_stata(...),pd.read_excel(...),pd.read_parquet(...),open(...),np.loadtxt(...) - R:
read.csv(...),read_csv(...),read.dta(...),haven::read_dta(...),readxl::read_excel(...),load(...) - Stata:
use "...",import delimited "...",import excel "...",insheet using "..." - Also check the
.mdJupytext pairs for the same patterns
- Python:
-
Extract every referenced file path and normalize it:
- Resolve relative paths from the notebook's directory (
notebooks/) - Resolve paths using
DATA_DIR,RAW_DATA_DIRfromconfig.py/config.R
- Resolve relative paths from the notebook's directory (
-
Check that each referenced file exists in
data/rawData/ordata/ -
Scan
data/rawData/anddata/for all data files present on disk -
Report three categories:
Resolved — referenced and found:
- File path, which notebook references it, line/cell number
Broken — referenced but not found:
- File path as written in code, which notebook, suggested fix (closest matching file, or note that it may need to be downloaded)
Undocumented — on disk but never referenced by any notebook:
- File path in
data/rawData/ordata/that no notebook loads
-
Print a summary: total references, resolved, broken, undocumented files
Error handling
- If no notebooks exist, report "No notebooks found" and stop.
- If
data/rawData/does not exist, warn but continue checkingdata/.

Use when the project collects primary data or runs a field, lab, or survey experiment, before the intervention begins — write the pre-analysis plan, size the sample from a power calculation, and register with the AEA RCT Registry. Apply after the design is chosen in aer-identification and before any outcome data are seen.
