Cytometry: single-window layout, study linking and a full notes editor

2026.10.20-cytometrie-depot-fcs-disposition · 2026-10-21

Delivered build : 1d4f0a05d3a01bd0f32b64e9fe994b728726ba5c

Changes

  • Cytometry: a single window (tubes, population tree, plot, gallery, mode rail), FCS drag and drop, one tube at a time or all tubes at once, Undo and Redo, context menus, freehand pencil, event inspector.
  • Metadata, Compensation (percent or ratio, heat map, previews), Quality, Diagrams and Reports modes, an axis scale panel, plot settings (histogram, contour, dot plot, palettes, resolution, smoothing) and extra statistics (standard deviation, CV, MAD, geometric mean).
  • The compensation matrix can be edited in the application: the file's own matrix is kept and you can revert to it at any time.
  • An analysis can be linked to a study and an execution: tubes come from the FCS files already attached to the execution's results, gate values go to the analysis workbook or back as execution results, and the study report shows a Cytometry block.
  • Gate statistics are no longer marked provisional: a gate drawn or modified by the user is validated automatically, and the export shows the validation and the author.
  • Otto: composite tools to prepare an analysis, propose a whole gating strategy in one confirmation and compare two groups; the geometry of automatic gates is computed from the data.
  • Executions: a planned session starts correctly again, and the "this device is behind" message no longer appears wrongly after each validated step. T-test reports name columns by their title, and a figure legend is prefilled with the test and the table read.
  • Journal notes: Edit, Insert, Format and Table menus as in a document editor, font, size, text and background colour, alignment, headings, subscript and superscript, table column widths and cell background. The server accepts only a bounded list of formats.

Known limitations

  • Conventional cytometry only; no tSNE, UMAP, FlowSOM or spectral cytometry.
  • Known gaps with usual cytometry tools: no compensation wizard, no gate copy and paste, no statistic heat map, no full quality-control panel and no child groups.
  • Medians have not been compared with reference data.
  • Note formatting is limited to the options offered by the toolbar and menus; a column width is only fixed once the column has been resized.
  • Cytometry features are added without changing laboratories' existing settings; no team under a GLP contract had signed at the date of this release.
