I am curious to know how to plot a group confusion matrix like in the TDT publication Figure 5A . The figure is very useful for decoding visualization, especially for multiclass classification. However, I can’t find such related descriptions in these demo scripts.
I have tried ROI-based decoding analysis with my own dataset for 4-conditions, but got only one value showing the accuracy to classify the 4-conditions. The problem is how can I get the exact value of each cell in the confusion matrix.
Should I change the default model parameters (train: ‘-s 0 -t 4 -c 1 -b 0 -q’; test: ‘-q’)? any suggestions?
Thank you in advance.
