[Stephen Yip]

Hi,

I have the x and y vector components store in a mhd file. I'd like to create
a 3d vector by using the calculator filter.

1. How do I find out the names of my x and y components?
2. I attempted to create the 3d vector by entering
Vector_x*iHat+Vector_y*jHat+0*kHat
or Vector_1*iHat+Vector_2*jHat+0*kHat. I then get the following error.

Thank you,
Stephen
