Petri dish guide
From photo to reviewed count.
Prepare a clear photo of an existing, closed dish. Upload a batch, check the proposals, correct the marks, and export the record.
Follow the Petri dish guide →Getting started
Your first experiment,
one clear step at a time.
Start with a task you already do. See what to bring, what to check, and what you can take back to your lab record.
Interactive practice
Try the review before you upload.
Explore a generated practice plate. Switch the overlay, edit a few marks, and download a practice CSV. No account needed.
Open the DishFlow demo →Instrument files
Start with a worked calculation.
For plate-reader and assay data, open the calculation demo, inspect its settings, and check the supported file formats before using your own export.
Try the assay demo →A useful first run
Bring one small, familiar experiment.
Choose work you can check against your original record. You should be able to explain the inputs, inspect the result, and understand what the export contains.
Keep the context
Use your existing experiment and plate IDs. Keep observation times, conditions, replicates, and source files together.
Check the result
Automatic proposals start the review. You decide whether the image or assay supports the conclusion you need.
Keep your originals
Save the export alongside the original photo or instrument file. The photo notebook keeps a resized review copy.
