request for help about Euler deconvolution on Oasis Montaj

hello dear colleagues,
I use version 8.4 of Oasis montaj and I want to apply the "Located An-Eul Solutions" (Euler3D Menu), do I have to go through "Located Euler Deconvolution"? because the "Located Euler Deconvolution" requires to introduce a value of the structural index while the "Located An-Eul Solutions" allows to calculate the structural index for each anomaly, but the latter does not calculate the x-Euler coordinates and y-Euler.
Thanks for your help
