Release 1.2.0

Version 1.2.0, released in the end of September, 2023, adds several more new features to GIMS:

  • Structure Builder
    • Optimized the Structure Viewer code, making it possible to visualize structures consisting of more than 15,000 atoms.

  • Control generator
    • Added sanity checks, which are used to compare the chosen calculation inputs against the structure and throw an error (or warning) if inconsistency is found.

    • Added new Extra keywords table, that allows a user to make as complicated file as they need (used at the user’s own risk; no constraints or sanity checks are run).

    • Rewritten and clarified help tooltips for the majority of the input parameters.

  • Output analyzer
    • Completely refactored Output Analyzer code.

    • Made plotly the new plotting backend.

  • Other
    • Added several new calculation apps, for GW and MD calculation, with included help and sanity checks.

    • Added CI pipeline to automatically produce standalone applications for Linux and Windows.

    • Added the first version of GW workflow, making it possible to produce the inputs and compare the outputs for several calculations at once.

    • Tests added, bugs fixed.

Should you come across a bug, please don’t hesitate to report it to our issue tracker.

Release 1.1.0

Well, it seems that some undocumented work has been done over the years…

Version 1.1.0, released in February, 2023, adds the following functionality to GIMS:

  • Structure Builder
    • A new Surface (Slab) construction field: allows a user to build the slab from the crystalline structure based on the Miller indices of the slab surface, the desired number of atomic layers of the slab and the thickness of the vacuum layer surrounding the slab. Once the slab is built, one can also terminate it with a layer of the desired chemical composition.

    • Added the Constrain/Release all atoms button to the Atoms section, making it simple to add a constraint to all atoms in one mouse click.

  • Control generator
    • Completely refactored Control Generator Form creation, effectively decoupling from the components the logic of one Form component acting on another. This made possible advanced filtering of the components shown based on the state of other components and the Structure given in the previous step.

    • Introduced a new Form component, RadioField, used for exclusive selection of one component from the group.

    • Added the output flags for Mulliken and Hirshfeld charge distributions.

  • Output analyzer
    • Added Mulliken and Hirshfeld charge distribution visualization.

  • Other
    • Fixed a bug with symmetry threshold not propagating correctly across different parts of code.

    • Added GIMS version selector in the header.

    • Rewritten the Docker file to get more stable and production-ready Docker environment; added CD rule pointing GIMS-dev server to the HEAD of the master branch of the repository.

    • Added end-to-end testing.

    Many bugs are fixed, (I hope not so) many are introduced. If you encounter a bug, we’d be happy if you report it to our issue tracker.

Release 1.0.0

(From June 03, 2020, to October 06, 2020)

With this new release we introduce semantic versioning of GIMS. The versioning we had before is deprecated. Once this release is finished, the corresponding commit will be tagged


  • Structure Builder
    • Multiple structure file upload: user can select several structure files. All uploaded structures are accessible via tabs.

    • New Supercell Button: user can create supercell either with simple multiples of lattice vectors (3 parameters) or with a supercell matrix (9 parameters). The new supercell will be created in a new tab.

    • Structure Info field: user gets additional information about structure, e.g. chemical formula, space group, occupied Wyckoff positions, ect. This feature integrate spglib in the backend of GIMS.

    • Primitive Button: New button in the side panel. It creates a new primitive structure (periodic systems only) in a new tab.

    • Brillouin Zone Viewer: If a periodic structure is loaded, the GIMS structure builder will automatically view the Brillouin zone of the Bravais lattice of the loaded structure. The BZ path according to Setyawan/Curtarolo, the cartesian Axis, and the reciprocal unit cell are shown as well.

  • Control Generator
    • Units (if applicable) are added to the input values

    • Rework input value structure (code structure): Each code has its own list of supported input values. Makes it more easier to include new codes.

  • Output Analyzer
    • Brillouin Zone Viewer added. BZ viewer displays actual path used in the calculation.

  • GIMS Backend
    • Restructuring of the backend: Backend is now organized as a python package (which simply allows a pip install . of the backend).

    • Extending backend tests.

  • GIMS Frontend
    • Restructuring of the dependencies: Some libraries, where the source code has been included in GIMS, have been removed. Instead, the corresponding libraries have been added as a dependency to the package.json file.

  • GIMS landing page
    • Small redesign to adapt the content to the description in the paper.

    • Add linkt to running GIMS versions and to the release notes.

Seventh release (r7)

(From March 18, 2020, to April 7, 2020)

This release improves several aspects of the project like testing, code documentation and adds some enhancements:

  • Enhancement: Consistent browser and in-app navigation. The usage of the browser native navigation elements is now consistent with the in-app navigation elements for the stand-alone apps as well as for the workflows.

Some important changes were required in the application:

  • Support of multiple instances of modules and nested modules inside another (e.g. StructureBuilder inside a workflow module). The StructureBuilder state is not a singleton longer.

  • Complete rewriting of the workflow implementation: The workflows are now implemented like application modules (Workflow.js) and contain UI components (modules or regular/simpler component)

  • URL based navigation point for every step in workflows: The URL is this way: #WorkflowName-workflow#StepComponentId

  • Wiki documentation piece updated and extended: Implementation details: workflows, application navigation. And Gitlab issue explaining the development process

  • Extension of the Front-End CI Testing-Suite. Some parts of the client are tested:
    • Output Analyzer module testing

    • The main output file parsing is tested for many combination of calculations (Single-point calculation, relaxation / Spin none, collinear / Band structure+DOS / Periodic, non-periodic / Exciting, FHI-aims).

    • Files parsing. The parsing of all the files making up the output is tested.

    • The parsing of the files containing the DOS and BandStructure data is tested.

  • File formats generated for exporting in Structure Builder. The functions that generate the different combination of file formats (molecule/periodic, aims/exciting, fractional/cartesian coordinates) to be exported are tested.

  • More details in this Gitlab issue

  • Code Documentation of Front-End. All the application code has been documented according to the JSDoc style

  • Enhancement: Refactoring Output-Analyzer. The OutputAnalyzer module has been deeply refactored, both the FHIaims and Exciting code parsers (Sebastian) and the user interface components: The OutputAnalyzerMod.js has been refactored to (electronic-structure-)code-independent.

  • Some minor UI improvements

Sixth release (r6)
