Help with placing basis function on dummy atom

Good evening,

I'm trying to place a single basis function on a specific coordinate, I have tried the following using dummy atoms based on the manual examples and a similar issue I saw posted here, but this is clearly not the correct approach as I'm getting a bunch of different errors:

&SEWARD
basis set
X....
X 100.000 100.000 100.000
end of basis set

end of basis set

My goal would ultimately be that of combining this with an actual molecule, but for now I am mainly interested in successfully placing this function in a specific coordinate.
Thanks for any help

Your second SEWARD works for me.

Re: Help with placing basis function on dummy atom

Dear Ignacio,

You're right, it works on its own, I had mistakenly thought this would require both declaring the dummy atom and the basis function, which is the reason I was getting the errors. Thank you for the help.
