PowerI4:
A power spectrum estimator with interlacing and
fourth-order interpolation
PowerI4 is an estimator of the Fourier-space density and
power spectrum of particle distributions in a simulation box
for cosmological applications and the analysis of N-body
results. It implements an interlacing technique and
4th-order interpolation that allow a reduction of aliasing
spurious contributions below the percent level for all
wavenumbers up to the Nyquist frequency. code: https://github.com/sefusatti/PowerI4

REPS:
REscaled Power Spectra for initial conditions with
massive neutrinos
REPS (REscaled Power Spectra) provides accurate, one-percent
level, numerical simulations of the initial conditions for
massive neutrino cosmologies, rescaling the late-time linear
power spectra to the simulation initial redshift.code: https://github.com/matteozennaro/reps
