The first author conducted random checks of data entry against original data sheets.
We're all about open journalism though, so it's important that your entry includes the original data you used to write the piece (in.csv,.xls,.kml or any other machine readable format).
Data were entered using an excel spreadsheet and checked for entry errors, by comparing data entries with the original data forms.
A systematic effort to look for out-of-range data was conducted by doing frequency distributions for each of the variables, identifying out-of-range entries and correcting the errors by going back to the original data sheets.
Inconsistencies between the 2 entries were checked against original data and errors were corrected.
Data entry errors or inconsistencies were corrected, where possible, by the principal investigator by referring to the original data collection forms.
The adherence to hard rules for structure validity is often appropriate for processing large databases with preexisting quality issues, but a heavy-handed approach is not appropriate for original data entry.
Written informed consent was obtained from each patient for original data entry.
A link from each LacED entry to the original entry in the NCBI peptide database allows the authors of the submitted sequence to trace the inconsistency and to correct the data.
A link from the reconciled LacED entry to the original NCBI peptide database entry allows the author of the respective entry to correct an erroneous entry.
A link from the reconciled SHVED entry to the original NCBI protein database entry allows the author of the respective entry to correct an erroneous entry.
