Dear FSL experts,
I am new to FSL FIX. In the 'fix4melview_<Training>_LOO_thr<thr>.txt', are labels on the 1st column, 'Signal', 'Unclassified Noise', and 'Unknown' predicted from the trained classifiers? Is the evaluation on the 2nd column, 'True' and 'False', determined by the prediction and the hand labeling?
For the LOO results, how should I interpret TPR and TNR of different thresholds?
Besides, is it necessary, or important, to redo hand labeling based on 'fix4melview_<Training>_LOO_thr<thr>.txt' results on each component?
Thank you!
