How to transfer a segmentation model

This guide shows you how to export a custom segmentation model from one computer to another.

Reference keys: Cellpose, StarDist, Experiment

Context

When you train a model in Celldetective, it is saved locally in the celldetective/models directory. To use this model on another machine (e.g., moving from a training workstation to an analysis laptop), you need to manually transfer the model files.

Step 1: Locate the model

  1. Navigate to your Celldetective installation folder.

  2. Go to celldetective/models/segmentation. * If you trained a specialized model (e.g., for effectors), check models/segmentation_effectors.

  3. Find the folder with your model’s name.

Step 2: Export the model

  1. Zip the folder: Right-click the model folder and compress it into a .zip archive. * Ensure the zip file contains the model configuration (JSON files) and weights.

Step 3: Import on the target machine

  1. Transfer the .zip file to the target computer (USB, network share, etc.).

  2. Open Celldetective on the target machine.

  3. Go to the Segmentation module.

  4. Click UPLOAD.

  5. Select StarDist or Cellpose depending on your model type.

  6. Click Choose File and select your .zip file (or the unzipped folder).

  7. Click Upload.

The model is now available in the “My Models” list on the new machine.
