The T1 image is segmented into probability maps and brain masks. The basic brain mask is where gray matter is prob > 0.05, and a liberal "brainmasklots" is created for use as a mask in analyses. This is initially set with prob > 0.1, but that actually does not make a huge difference:
| prob > 0. |
|---|
| 5 | prob > 0. |
|---|
| 1 | prob > 0.1, close with sphere r = 7 | |
|---|---|---|
