[Camino-users] Information

[Philip A Cook]

Hi,

The three numbers are the orientation of the principal direction (eigenvector with largest eigenvalue), in voxel coordinates. The number in parantheses is the value of the underlying scalar background, which by default is FA. If you'd like it to be a particular eigenvalue, you can use "-scalarfile" to use that image in place of FA.

Your error message suggests a problem with your scheme file. Since this is the example scheme file, I suspect some kind of platform dependent parsing problem. Just to be sure, can you send me your scheme file? Also, what OS you are running on, and if you have the system configured for a language other than English. These things can affect how Java processes text.

Thanks

Are the 3 numbers  before the round parentheses the eigenvalues and the value in round parentheses the FA or MD?
