simple-main-pftc

name	simple-main-pftc
description	Use when working in SIMPLE's src/main/pftc subsystem, including polar Fourier transform calculation, correlation, geometry, memoization, CTF-aware paths, restore/state operations, and search support for alignment workflows.

SIMPLE src/main/pftc

This folder is central to polar-Fourier search workflows.

Read First

• simple_polarft_calc.f90
• simple_polarft_core.f90
• simple_polarft_corr.f90
• simple_polarft_geom.f90
• simple_polarft_memo.f90
• simple_polarft_ctf.f90

Structure

• The public type is declared centrally and much behavior lives in submodules
• Memoization and restore/state code are first-class concerns here

Connections

• Tight coupling with image/, interp/, ctf/, ori/, and strategies/search

Working Rule

Changes here often affect alignment performance and correctness simultaneously, so treat caching and geometry logic as part of the design, not incidental detail.
