Features of PSCF programs are listed below, grouped so as to indicate the programs and computational methods to which they apply:

Common features for SCFT and FTS (all programs):

Ability to treat mixtures containing any number of block polymer and solvent molecular species. Linear homopolymers are treated as a special case of a block polymer with only one block.
Ability to treat acyclic branched block polymers of arbitrary complexity, as well as linear block polymers
Ability to use canonical, grand-canonical or mixed statistical ensembles. Users may specify either a volume fraction or a chemical potential value for each molecular species
Thorough user and developer documentation provided via an integrated web manual
Well documented open source code written in object oriented C++
A library of examples containing input files for many types of calculation
Python tools for data analysis and manipulation of input and output files

Features for SCFT (all programs):

Efficient Anderson-mixing SCFT iteration algorithms
Efficient SCFT calculations for sequences of parameter choices along a path in parameter space ("sweeps"), using extrapolation to construct initial guesses

All features listed below are specific to the pscf_pc and pscf_pg programs. Both of these programs are designed for systems with periodic boundary conditions and provide very similar features. Both can be used perform either SCFT or PS-FTS calculations. In SCFT, the periodic computational unit cell is usually chosen so as to represent a single crystallographic unit cell, whereas in FTS it may represent a larger region.

Features for SCFT or PS-FTS on periodic systems (pscf_pc and pscf_pg):

Accurate pseudo-spectral solution of the modified diffusion equation for a continuous chain using an algorithm that is accurate to 4th order in the contour length step size
Periodic unit cells with 1, 2 or 3 dimensional periodicity
Unit cells with all possible 2D and 3D Bravais lattice systems (i.e., cubic, orthorhombic, monoclinic, etc.)
A companion matlab package Polymer Visual for visualization of structures with periodic boundary conditions

Features for SCFT on periodic systems (pscf_pc and pscf_pg):

Efficient algorithms to optimize unit cell parameters in SCFT so as to minimize free energy density
Imposition of any user-selected space-group symmetry on SCFT solutions
Built-in database of symmetry operations for all 230 3D space groups and 17 2D plane groups for use in SCFT
Inhomogeneous density constraints (a "mask")
External fields
Thin polymer films (implemented using a mask and external fields)

Features for PS-FTS (pscf_pc and pscf_pg):

Brownian dynamics (BD) and Monte Carlo (MC) sampling
BD algorithms: Leimkuhler-Matthews and predictor-corrector step algorithms
MC move algorithms: real-space and "smart"/force-bias moves
Efficient algorithms for adjusting the pressure field so as to find a partial saddle-point (i.e., to impose incompressibility)
Tools for calculation of free energy differences by thermodynamic integration, including the Einstein-crystal integration method
Parameter "ramps" in which one or more parameters change continuously during a simulation, which can be used for continuous thermodynamic integration
Analysis tools to compute several quantities of interest, including the structure factor, order parameters used to identify phase transitions, and derivatives of the Hamiltonian needed for thermodynamic integration calculations
Analysis tools can applied either during a simulation or during postprocessing of field trajectory files that are created during an earlier simulation.
