autoFISH - automated FISH experiments

Python library to control an automated fluidics system and perform acquisition on a microscope for sequential FISH experiments.

⚠️ TESTED FOR WINDOWS only: micromanager and most microscope controls work only under Windows.

Protocols for smFISH experiments

We provide detailed protocols for single molecule FISH adapated to autoFISH here.

Documentation

We provide details documentation for the fluidics system and the experimental workflows with the links below:

Fluidics system and software usage

• Documentation to use Python control software: PDF or WORD

• Documentation to build the fluidics system: PDF or WORD

• Documentation to use a TTL trigger with the LEICA Thunder: PDF or WORD

Getting started

Installation

We recommend using a package manager (conda) to maintain a clean Python installation. This nees to be done only once.

1. Download latest version of miniconda from here.
2. Open Anaconda terminal and create dedicated environment: conda create --name autofish python=3.10
3. Activate environment: conda activate autofish
4. Pip install autofish (as an alternative see development installation below)
   • Base version (without pycromanager) : pip install autofish
   • [Optional] Install pycromanager : pip install pycromanager

Starting autofish

1. Open Anaconda terminal and activate environment: conda activate autofish
2. Start user interface with command autofish

Upgrading to a new version

1. Open Anaconda terminal and activate environment: conda activate autofish
2. Upgrade autoFISH pip install --upgrade autofish

Development installation

If you want to modify develop the package, several options exist.

1. Recommended is to clone the repository. This will then also allow to propose your changes to the main autoFISH repository as a PullRequest. See for instance here for an explanation for how this is done. This also allows to easier add changes from the main repository

2. An alternative is a local installation. While this might be easier in the short run, it will be challenig to integrate future changes on the main repository. Rather than performing the pip install (step 4 above), you

   1. Download the zip archive of the branch you are interested in.
   2. Unzip on your machine.
   3. Open Anaconda terminal at location of the autofish package.
   4. Activate environment: conda activate autofish
   5. Editable install pip install . -e

Configuration files

The behavior of the fluidics and acquistion system is defined by several config files.

• To test the installation of autofish, you can use demo configurations which require neither a microscope nor a fluidics systems: https://github.com/fish-quant/autofish/tree/main/demo

• We provide config files that we use on our system (with a Nikon Ti): https://github.com/fish-quant/autofish/tree/main/configs

Pycromanager

One of the acquisition options is by using Pycromanager. We found that keeping both micromanager and Pycromanager up-to-date can help to prevent problems.

Last tested, compatible versions:

• Pycromanager: 0.27.2
• Micromanager: nightly 20230224
