Fix pour gives an error 'atom attributes radius, rmass'

I am working on the ‘Pour 3D with ellipsoids’.

The below line keeps giving me an error, ‘Fix pour requires atom attributes radius, rmass’
I have set the mass and shape for ellipsoid particles and using pair_style gayberne

fix ins all pour 3000 1 300719 region insreg diam one 0.5 dens 1.0 1.0

when I revised the line to not have diam and dens, it still gives same error.

Yes, but not the radius. Fix pour is for granular particles, which use atom style sphere.
As the error message indicates, it is not compatible with atom style ellipsoid since that does not include a radius property (the diameter(s) of the ellipsoids are set in the pair_coeff commands and per-type and not per-atom).
