Dear FSL experts:
When extracting brain in DTI, I find that the different threshold have different extraction results,0.2 is better among them.
Therefore I have the following questions:
1. When extracting brain , do I have to choose a specified threshold first and then visually check the extraction result ?
If so , how much is usually the specified threshold ?
2. Do you have any better suggestion to tell me that how to choose threshold ?
Thank you very much .
