Images

The Images tab lists every image file found in the configured image directory. If a single image was opened using the Open button all the other images from the directory this image is placed in are also displayed there.

All discovered images are shown in a table. Use the search field at the top to filter by filename.

Click any row to:

  • Load the image in the viewport for preview.
  • Display image metadata in the meta panel below - dimensions, pixel size, number of channels, Z planes, and time frames.

The selected image is also the one used as the live preview source when editing pipeline parameters.

Selecting an image fills the Image Meta panel with detailed meta information about the image.

Image Meta panel

Use the Calibration section to correct pixel size if it was not embedded correctly in the source file - this affects the scale bar and all physical-unit measurements (area, distance) calculated during analysis.

The viewer panel shows the selected image with the following controls:

For multi-channel images, each channel can be independently configured:

  • Visibility toggle - show or hide a channel in the composite view.
  • Colour assignment - map a greyscale channel to a display colour (e.g. blue for DAPI, red for Cy5).
  • Brightness / contrast - per-channel min/max input range.
  • Auto-adjust - automatically set min/max from the image histogram.

When an image has multiple Z planes:

  • Use the Z-plane slider to step through individual planes.
  • Switch between projection modes (Max, Min, Avg, Sum, Middle) in the toolbar.

When an image has multiple time frames:

  • Click Play in the toolbar to animate the sequence.
  • Set the playback speed in frames per second.

A physical scale bar is overlaid on the image. The units are nm, µm or mm based on the actual zoom level. Pixel sizes are read from the image metadata.

If the image does not contain pixel size information use the Calibration section to define it manually.

For large images, a thumbnail minimap in the corner shows the full image with the current viewport highlighted.

As you move the mouse over the viewport, a HUD overlay in the top-left corner shows the cursor’s position (in physical units, using the calibrated pixel size) and the pixel value for every visible channel.

Position and pixel value readout

This is a live readout that updates continuously with mouse movement - it does not place a persistent measurement marker.

To place a persistent measurement use the cross fade button from the toolbar and click on the wanted position in the image. A permanent marker with the intensity values of all image channels is displayed. Right click on the permanent marker to remove it.

Draw manual regions of interest directly on the image:

  • Rectangle - drag to define a rectangular ROI.
  • Oval - drag to define an oval/elliptical ROI.
  • Polygon - click to place vertices, double-click to close.

Annotations are saved per-image to the project file and are preserved across sessions.

Some image formats (e.g. LIF, CZI) store multiple image series in a single file. Select the desired series index in the properties panel to analyze a specific sub-image.

See Image Formats for the full list of supported file types.
