Table 2.

Detection results for both MRI-positive and MRI-negative subjects. For each subject the true-positive rate (TPR) and false-positive rate (FPR) are calculated as the percentage of lesional vertices correctly labeled, and the percentage of non-lesional vertices incorrectly labeled, respectively. The dice coefficient (DC) is also shown as a percentage to quantify the overlap between the detected clusters and the resection on the cortical surface.
