### CAMB: initial condition

Hello. I have question about initial condition in CAMB.
I know that initial clxg, i.e. related with initial power spectra().
But I couldn't find that.
I would like to know where the part that relation between initial condition and initial power spectra is.
I thought it will be in power_tilt.f90, but I couldn't find that.
Where can I find that?

Thank you for any help.

The series solutions for the initial perturbations are set in initial(...) in equations.f90.
