Hi,

Thank you again for responding to my previous questions! 

I'm writing a python class to show MR images, and I need to have one brain MRI volume (e.g. nifti or mgz) in which left and right are labeled in some way. 

FSL website used to provide a test MRI volume that was labeled:

Unfortunately I can't find this volume on the internet anymore! So I need help :) 

Thank you,
Arman
