Focus 1.0 is the first version released for the users and is in beta stage. The current minor release version is 1.0.0
Installation and setup
Focus depends on Qt5 for deploying a GUI. Other EM Suites are used wherever required. Find information on how to download, install and setup Focus software for the first time.
Once Focus is installed it can be easily launched using the Command line or Desktop utilities provided with Focus. Following links give more information on launching Focus, adding a project, configuring global user settings and brief introduction of the GUI.
The links below would help you to start using Focus. The first things to do in any project is to import images and later once imported process them and manage them. Processing depends on the type of EM method used and is detailed in later sections.
Focus allows to process images via the precompiled scripts. Each script calls a few executables (external or internal) and fetches parameters associated with the project or the image from the configuration files as required. Processing can be either done manually for each image allowing to tune-in the parameters and later a bunch of images can be processed in parallel.
Remote monitoring allows to see the status of the processing in Focus from a website that can be accessed remotely. This in turn helps to check the recording status of the microscope.
2D Crystal Processing
Focus includes scripts prebuilt to carry out complete 2D crystallographic image processing. Following pages describe how to start from images/movies, create final 2D maps, merge the data to produce 3D and finally refine the reconstruction to minimise the effects of missing cone.
Exporting the data
Once the images have been processed they can be exported. The export function in Focus organizes the image files and metadata in the arrangement required by the target package. For example, if the target package is RELION, the data will be reorganized so that all aligned average images and a single metadata STAR file are created in a single subfolder. On the other hand, if the target package is IMOD, the electron tomography data will be reorganized so that there is one MRC stack for each specimen location, containing the entire tilt series ordered by tilt angle, irrespective of the recording order (e.g., if they were acquired using the Hagen scheme).
