**v_ase 0.4.3 — clearer scientific controls, synchronized trajectories and GIF export** ·
[Changes](https://v-ase.readthedocs.io/en/latest/whats-new.html)

An ASE-native workspace for building, editing and visualizing atomic structures,
trajectories and volumetric data.

![Phosphorene nanoribbon manipulation](https://raw.githubusercontent.com/lgyEthan/v_ase/main/docs/assets/github/readme_phosphorene_twist.gif)

Trajectory navigation retains double-precision coordinates and committed edits
through frame switches, animation output and scientific project exports.
Renderer scale and atom radius remain independent.

## Installation And Launch

macOS and Windows users can install the self-contained
[desktop app](https://v-ase.readthedocs.io/en/latest/desktop.html) from
[GitHub Releases](https://github.com/lgyEthan/v_ase/releases/tag/v0.4.3).
It runs the same GUI with native Command/Ctrl shortcuts and file dialogs;
Python installation is not required. Python and Jupyter remain available
independently. Drag a desktop tab out to detach it into another window.
Dropped files offer trajectory, new-tab and new-window destinations. Each
window closes independently; Windows Alt+F4 closes the active window, while
explicit Quit checks all windows. The app icon now features the full atomic-bead
castle with its small Pinocchio detail and no projecting red foundation board.

| Desktop download (0.4.3) | Install and launch |
| --- | --- |
| [Mac, Apple silicon](https://github.com/lgyEthan/v_ase/releases/download/v0.4.3/v_ase-0.4.3-mac-arm64.dmg) | macOS 15+: open the DMG, drag **v_ase** to **Applications**, eject the disk image, then launch the Applications copy. |
| [Mac, Intel](https://github.com/lgyEthan/v_ase/releases/download/v0.4.3/v_ase-0.4.3-mac-x64.dmg) | Same steps; choose Intel when **About This Mac** shows an Intel processor. |
| [Windows, Intel/AMD x64](https://github.com/lgyEthan/v_ase/releases/download/v0.4.3/v_ase-0.4.3-win-x64.exe) | Windows 10/11, 64-bit: run the EXE installer, complete installation, then launch **v_ase** from Start. |

The Mac downloads are **Developer ID signed and Apple-notarized**, with
stapled tickets for the app and DMG. macOS may show its normal first-open
confirmation for an internet download. The Windows build is **not yet
publisher-signed**; after verifying its source and checksum, a SmartScreen
prompt may offer **More info → Run anyway**. Do not disable OS protection.
[Step-by-step installation, ZIPs, checksums and troubleshooting](https://v-ase.readthedocs.io/en/latest/desktop.html).
Maintainer build, signing and notarization steps are in
[the desktop build guide](desktop/README.md).

`.vase` is registered as a project type. To make double-click use v_ase, choose
**Get Info → Open with → v_ase → Change All** on Mac, or **Open with → Choose
another app → v_ase → Always** on Windows. You can also select v_ase for
`.vasp`, `.xyz` and `.cif`; browse to the installed application if it is not
listed. Extensionless `POSCAR`/`CONTCAR` can be opened using **File → Open**.
[Complete file-association instructions](https://v-ase.readthedocs.io/en/latest/desktop.html#open-vase-by-default).

For the Python/browser/Jupyter installation:

```bash
python -m pip install v_ase-gui
v_ase gui POSCAR
```

Use `v_ase gui` for an empty workspace or `--interactive` to edit a file.

## Save And Share

One HTML file for offline viewing and project recovery.
[Project HTML](https://v-ase.readthedocs.io/en/latest/save-projects.html#project-html) · [Export HTML View](https://v-ase.readthedocs.io/en/latest/save-projects.html#html-view)

The editor keeps the atomic viewport wide, with no permanent left navigator.
The optional **Objects** drawer overlays the scene, while the right workbench
has **Style / Build / Analyze / Render** tabs. An icon bookmark strip sits above
the selected section title; hover or keyboard-focus an icon to see its name.
Each section has its own symbol, including selection Transform, Cell matrix and
energy-minimization Relax. Search in the header finds existing controls.
The left icon toolbar separates selection/measurement, transforms of selected
objects, camera orbit and object creation. Move/Rotate/Scale require an editable
selection; click one and drag in the viewport, or enter an axis and value.
Apply/Enter confirms, Cancel/Escape restores the original, and switching tools
cancels a provisional transform. Keyboard G/R/S retains its modal workflow.
Saved per-atom colorscales are applied before a reopened project is ready to render.
Atom appearance uses compact per-label rows with horizontal scrolling, distinct
scope headings, and explicit property/range/target controls. Scrollable tables
keep their headers flush with the top border, including Relaxation cutoffs. **Fixed atom
selection** captures colorscale targets until you choose **Use current selection**;
selection changes never redirect the mapping. Trajectory coordinates, colors and
radii are presented together. **Show output frame** draws a crop guide over the
editable canvas. Video supports inclusive source-frame ranges and animated GIF
with **Loop forever** or **Play once**, alongside MOV/AVI.
Desktop project and structure files have paper-shaped document icons bearing
the castle; the application keeps its full castle icon. Only `.vase` is registered
as the native default type. Structure formats including `.extxyz`, `.xyz`, `.vasp`
and `.cif` appear under **Open with** without changing their existing defaults.
An empty workspace opens its first file without replacement/append choices.
The right panel overlays the scene without shifting the camera and expands up
to 900 px when the window permits. Bonds opens editable pair specifications by
default; **Reset to suggested cutoffs** restores radius-derived suggestions.
Ctrl+A selects the entire number in an input on Mac as well as Windows; Tab and
Shift+Tab move through successive bond cutoffs. The visible Reset menu offers
coordinates-only and full reset. Open uses Command+O on Mac / Ctrl+O on Windows. **Fit view** or F frames the structure when the viewport has focus.
Save
reuses an approved writable project target; Save As chooses a new one. When
the browser only supports downloads, v_ase labels the result a copy rather
than implying it can overwrite the original. Closing a changed document
offers Save, Discard and Cancel and keeps a replacement blank tab when the
last tab closes. Direct and notebook editors adopt tabs in place without
reloading the original document. Pending physical edits settle before Save,
Close or Replace can discard anything; invalid scientific inputs block Save
before a file destination is chosen. Uploaded project tabs retain their
format and writable target after an internal-tab reload, including after
Save As. Clean saved appearance and the latest unsaved visual edits survive
child-tab reloads. Exact delivered Command shortcuts on macOS and Ctrl
shortcuts on Windows/Linux are listed in
[Keyboard shortcuts](https://v-ase.readthedocs.io/en/latest/shortcuts.html).
Plain arrow keys orbit or tilt the structure view; Option+Left/Right on macOS
or Alt+Left/Right on Windows/Linux steps the selected trajectory. A single
atom's Measure readout leads with its chemical element and user label rather
than a property count.
Analysis plots open in a resizable dock below the canvas, with a full-work-area
Back view on short windows.

Render → Renderer exposes lighting, quality, output dimensions and an
independent physical output scale (px/Å); changing that scale does not zoom the
live viewport or resize atom glyphs. Image, Video and Interactive HTML each
have format-specific settings next to their export action; changing an
export draft and canceling its dialog leaves the project profile unchanged.
Objects lists loaded field objects and opens their actual isosurface and plane
property controls; Analyze retains field import, processing and combinations.
Objects also links vector layers and their live style controls, while Build
separates selection transforms from periodic-cell
matching and rigid translation from Analyze's translation map. Command search
can reveal a matching control directly. Replacing a dirty tab asks Save,
Discard or Cancel; uploaded HTML projects keep their HTML save profile when
opened in a new tab. Fullscreen editing requests Keyboard Lock where the browser
permits it; the status distinguishes active, denied and unsupported capture.
File-menu controls remain available when reserved keys cannot be captured.

## Analyze Structures And Fields

### Ordered Geometry

Click 2, 3 or 4 atoms deliberately in order for distance, angle or torsion.
Marquee, label and Select all selections show a count without incidental geometry.
[Measurements](https://v-ase.readthedocs.io/en/latest/selection.html#ordered-geometry-through-a-trajectory)

### Property-based atom size

The Atom appearance controls include a global-size slider with a numeric input
and an independent per-atom property radius mapping. Select an available
numeric field, input range, minimum/maximum size multipliers and exponent.
Enabling the mapping first reveals the field picker; it does not apply a
placeholder property. Custom and charge presets fit the displayed frame's
finite values, including signed data and the frozen atom scope.
The mapping multiplies existing label and selected-atom sizing; a zero factor
hides the glyph, not its scientific atom or bonds. Current and trajectory fits
lock their resulting limits until fitted again.
[Field, scope, fit and export details](https://v-ase.readthedocs.io/en/latest/property-radius.html).
