Hi Saad,

Now that I have my individual subjects, MNI registered x, y, z vector
maps -  How would you recommend comparing the following:
Controls vs Patients X-vector maps
Controls vs Patients Y-vector maps
Controls vs Patients Z-vector maps

Would these pre-registered maps lose any vital integrity by being
uploaded into SPM for a simply VBM t-test comparison?

Is there a way to set up something similar within FSL?

Thank you very much,
Catherine

Hi - you can use fslroi for this.

Hello experts -

Would you happen to know any programs or scripts that could help create

individual x, y, z vector maps from a primary eigenvector map?

Currently, I use FSL and get both dyads1* output from the bedpostx and V1

output from dtifit.

I would like to find a way to extract the 3 vector components from the

maps.

Thanks in advance for your time and help,

Catherine
