Job: Patch CTF Extraction


Patch CTF Extraction takes particle pick locations and a CTF defocus landscape (as outputted by Patch CTF Estimation), and outputs particle pick locations along with per-particle CTF information. This is useful where particle picking has been performed on micrographs that have not yet been processed with Patch CTF Estimation. If following a standard cryoSPARC workflow, where Patch CTF Estimation is used on micrographs, followed by particle picking and extraction, this job is not needed.
