Dioptra is free. Dioptra Lab is for labs that run the same work every week.

Every table, formula, analysis, graph and export is free and MIT-licensed, for anyone, for any use. Lab is a yearly license for batch analysis, instrument import, journal figure checks, Prism hand-off, regulated records and site licenses.

02 What Lab contains

Five groups, and what stays free in each

1. Batch analysis and instrument import

Save a project as a template and apply it to a folder of data files: every analysis, graph and layout is recomputed, with a summary table such as EC50 per plate. Read SoftMax Pro, BMG MARS, Gen5 and Magellan exports, endpoint and kinetic, through a plate map. A watch folder analyses each new export as it lands; dioptra batch does the same from the command line.

Free: importing one plate-reader file, the full command line, re-running a project on new data by hand.

2. Journal figures and reports

Presets for Nature, Cell Press, Science, PLOS, eLife, ACS, Elsevier, APS and JPhysiol: width, fonts, line widths, DPI and file type, applied to every graph at once. A figure check for small text, thin lines, low resolution, colour pairs a colour-blind reader cannot tell apart, and mismatched fonts. Layouts at final size with panel letters. A methods paragraph with references, and a Word or PDF report of the project.

Free: SVG, PDF and PNG at any size, multi-panel layouts, colour-blind-safe palettes, the one-line methods text on each results sheet.

3. Prism hand-off

Write .pzfx files that Prism 5 and later opens: data tables with replicates, formats, row titles and exclusions, for a PI or collaborator who still uses Prism. Convert a folder of .pzfx and .prism files to .dioptra in one step, with a report of what did not carry over.

Free: opening .pzfx and .prism files, however many.

4. Records for regulated labs

The technical controls of 21 CFR Part 11 and EU Annex 11 on a desktop without a server: named users and roles, an append-only hash-chained audit trail, electronic signatures bound to the record, and a validation pack with IQ and OQ protocols and an automated OQ that reruns the NIST and reference suites. Dioptra supports Part 11 compliance; the customer writes the SOPs and runs the PQ.

Free: the command history of every project, and verifying a file's audit trail and signatures.

5. Site licenses and support

One key for a department or institution, with no license server, no seat counting and nothing to install beyond the app. A shared template library on a network or synced folder. Email support with a reply within two working days, numerical questions answered with a reference, and early builds.

03 The license

A key, not an account

Offline. A key is a signed statement of who it is for, the plan and the dates. The app checks the signature itself and never contacts a server, so it works on air-gapped instruments and behind firewalls. Enter it under Help, Dioptra Lab.
Per person. Use your key on every computer where you are the main user. A site key covers everyone at the site.
30 days of grace. Lab features stay on for 30 days after the end date, then pause until a renewed key is entered.
Your projects always open. When Lab pauses, projects, data, reports and figures made with it keep opening, audit trails and signatures stay verifiable, and templates can still be applied one file at a time.
Readable source. The Lab code is published in the repository under the Dioptra Lab License, so it can be read and audited. Everything else is MIT.

04 Questions

Questions

I am a student. Do I need Lab?: No. Everything a course, a thesis or a paper needs is in the free version: all tables, formulas, analyses, graphs and exports, and opening Prism files. Lab is for repeated, high-volume or regulated work.
Can a site pay by invoice or purchase order?: Yes. Email the Dioptra Lab address with the organisation, the number of people and the purchase order, and an invoice will follow. Corporate sites are quoted the same way.
Can I get a refund?: Yes, within 30 days of purchase, for any reason. Ask by email or through the Paddle receipt.
Who handles VAT and sales tax?: Paddle sells Dioptra Lab as the merchant of record. It charges and remits VAT or sales tax for your country and issues the receipt or invoice.
Does this page track me?: No. There are no analytics, trackers or cookies here. Nothing from Paddle loads until you press a buy button.
What happens to the free version?: It stays free and MIT-licensed. Nothing in it moves to Lab.
