Additionally, errors in the molecular formula may arise from workflows involving redundant human interventions. The accurate mass measurement itself includes an internal control mechanism: an incorrect molecular formula will not lead to a matching mass measurement. Errors occur if an incorrect formula is paired with the calculated and measured mass after the measurement. This can happen due to incorrect formula transfer (e.g., mistyping) or by pairing the numeric data with a newly generated formula. The script catches these mistakes and suggests a formula that does fit the calculated and measured masses by modulating the atomic composition of the given incorrect molecular formula (Figure , section c). Similar human-in-the-loop errors can occur when manually retyping numerical values from a printed report instead of directly transferring them into the SI. Common mistakes include transposition errors, where two adjacent digits are swapped, and substitution errors, such as typing "8" instead of "9" due to the proximity of keys on the keyboard (see Figure , section d).
