Getting started

I have downloaded the code onto my Mac with condo.
It passed its internal test.
What can I do next?
The command psi4 gives an error
psi4 <./test, where ./test is the first calculation of your recent paper gives the same error.

psi4 takes an input file as argument not a redirect through <. You could look in shared/psi4/samples for an input file of something you’d like to run, then execute psi4 input.dat. Look at the results in output.dat
