How does the supercomputer that translates to binary code all the information received by ALMA antennas operate? In this episode, Lorenzo Martínez-Conde, an engineer who has been working at ALMA Observatory for 15 years, explains how the brain of the system behind this radio telescope operates and how each piece of information we have about the Cosmos is obtained through a complicated mathematical process that synthesizes the observations made.Let's journey through the two essential correlators of ALMA's Little Universe.

Abstract: Cryo-correlative light and electron microscopy (CLEM) is a technique that uses the spatiotemporal cues from fluorescence light microscopy (FLM) to investigate the high-resolution ultrastructure of biological samples by cryo-electron microscopy (cryo-EM). Cryo-CLEM provides advantages for identifying and distinguishing fluorescently labeled proteins, macromolecular complexes, and organelles from the cellular environment. Challenges remain on how correlation workflows and software tools are implemented on different microscope platforms to support microscopy-driven structural studies. Here, we present an open-source desktop application tool, CorRelator, to bridge between cryo-FLM and cryo-EM/ET data collection instruments. CorRelator was designed to be flexible for both on-the-fly and post-acquisition correlation schemes. The CorRelator workflow is easily adapted to any fluorescence and transmission electron microscope (TEM) system configuration. CorRelator was benchmarked under cryogenic and ambient temperature conditions using several FLM and TEM instruments, demonstrating that CorRelator is a rapid and efficient application for image and position registration in CLEM studies. CorRelator is a cross-platform software featuring an intuitive Graphical User Interface (GUI) that guides the user through the correlation process.
