Thanks again for the pointer, Bruce.

You wrote:

…  mri_convert -rl rawavg.mgz <input vol> <output vol>

which does produce an output volume from which I now need to extract RAS voxel coordinates.

A pointer to a keyboard command would be most welcome.

Of interest is the difference between the color mappings for the input and output volumes in freeview.

When using the lookup table in freeview they are quite different whereas in grayscale they are almost identical.

I wonder if this is contributing to my difficulty in finding a tool to extract the voxel coordinates.

Thanks again.

Regards,

Don
