Existing labels are the labels that the current loaded volume contains. For example, 1109 exists in the look up table. But the volume you loaded does not contain that label. So it is not possible to show that label for the volume.

Dear FreeSurfer experts,

I have two questions please.

1- I cannot understand the concept of "existing labels". Why few labels (such as #19) do exist in the LUT, but they cannot be overlaid on the brain? What should I do if I need to map one of those labels on the brain that disappear when I press the button of "existing labels"?

2- I can see that the 11115 label is named as ctx-lh-G-front-middle, and the 1109 label is named as ctx-lh-G-frontal-middle. Is there any difference between these two? If yes, what is the difference? If no, why their name is different? (The 1109 label disappears when pressing the existing labels button)
