Octopus 1.1.0

Octopus 1.1.0

Save and Load Layout

• Save a generated layout together with its settings and covariate colors, then load it back to reproduce the exact plate arrangement.
• Layouts are saved as a JSON file.
• Saved layout files record the app version that produced them, for provenance.
• Export controls are consolidated into a single Export menu.
• Every export now gets a timestamp in its filename, so repeated exports no longer overwrite each other.
• Loading a sample CSV or a layout JSON file now first validates it, and confirms before overwriting a displayed plate layout.
• Plate detail tooltips are hardened so they can use parentheses.
• (#21, #22, #23, #24)

Group Distribution Warnings

• The Covariate Summary now flags covariate groups that are poorly distributed across plates or rows, without blocking plate generation.
• A treatment group with fewer samples than the number of plates is flagged, since it cannot be placed on every plate.
• A QC / reference group that is missing from a used row of the generated layout is flagged.
• A group that is present on every plate but is spread unevenly (Poor or Bad balance) is flagged.
• Moving samples within or across plates updates the Covariate Summary and its warnings automatically.
• (#28)

N/A values setting

• A new "N/A values" setting unifies how blank or not-applicable covariate values are grouped.
• Builds on a fix for a | in a covariate value corrupting grouping, plate details, and the Excel export.
• (#25, #26, #27)

Stricter CSV reading

• Files that are not a simple sample table are now rejected with a clear message instead of loading silently.
• This covers duplicate or empty column headers and rows that do not line up with the header.
• (#29)

Downloadable offline app

• Every release now attaches a single self-contained HTML (e.g. octopus-1.1.0.html) that can be downloaded and opened in a browser.
• No internet connection is required, since all code, styles, and images are built in.s
• Releases are produced automatically.
• (#31)

Octopus name and icon

• The Octopus name and icon now show in the browser tab.
• (#30)
