Yes! The iMRMC can analyze single reader data. The key is how to format the data as the input file. First, create ROC data input file following the documentation. Then, edit the input file as following.
Duplicate the single reader's data with a new and different reader ID.
Original input file:
| readerID | caseID | modalityID | score |
|---|---|---|---|
| truth | posCase1 | truth | 1 |
| truth | negCase1 | truth | 0 |
| Reader1 | posCase1 | modalityA | 1.45 |
| Reader1 | posCase1 | modalityB | 1.98 |
| Reader1 | negCase1 | modalityA | -1.11 |
| Reader1 | negCase1 | modalityB | -0.87 |
New input file: Duplicate reader1's result with a new reader ID "reader2"
| readerID | caseID | modalityID | score |
|---|---|---|---|
| truth | posCase1 | truth | 1 |
| truth | negCase1 | truth | 0 |
| Reader1 | posCase1 | modalityA | 1.45 |
| Reader1 | posCase1 | modalityB | 1.98 |
| Reader1 | negCase1 | modalityA | -1.11 |
| Reader1 | negCase1 | modalityB | -0.87 |
| Reader2 | posCase1 | modalityA | 1.45 |
| Reader2 | posCase1 | modalityB | 1.98 |
| Reader2 | negCase1 | modalityA | -1.11 |
| Reader2 | negCase1 | modalityB | -0.87 |
