Macro Programming in ImageJ, Oct 18th

ImageJ is an open source image processing software designed for scientific image analysis. Its most often used distribution is called Fiji. This software has a lot of built-in functions and plugins. ImageJ has its own programming language based on Java. As scientists, we often want to perform image analysis on large datasets (detecting hundreds of particles on hundreds of images). If you don’t want to click the dots for all eternity, writing a macro is the perfect solution.

During this workshop you will learn how to automate some of your analyses by writing simple macros in ImageJ. Prerequisites for this workshop are basic skills in any programming language as well as basic knowledge of what ImageJ can do.

Workshop will take place October 18th, 10AM – 3 PM. Please find the application form here. We wait for applications until Oct 10 th. The cost of the workshop is 60 PLN.

Please install Fiji before workshop (https://fiji.sc/).

Kacper Łukasiewicz recently finished his PhD in the laboratory of Molecular Basis of Behavior, Nencki Institute. During his PhD he worked on alcohol-induced memory impairment and analyzed hundreds of images from immunostainings (and saved hundreds of hours using ImageJ macros for this).

Join us!

As our Nencki Open Lab project is dynamically developing, we are currently looking for PhD students and other scientists Ochota Campus who would like to join us!

Our plans for the following year include: workshops: i.a. Matlab programming, optics (we plan to build a fluorescent microscope from scratch!), 3D printing, analysis of behavioural data, Arduino, electronics, LaTeX and others; the next edition Nencki Open Lab Summer School on Behavioral Neuroscience and weekly seminars.

There are many ways in which you can contribute to the project:

  • organizing workshops – preparing announcements, spreading information about workshops on social media, taking care of workshop logistics

Deep Learning Workshop, June 10-12th

We would like to invite you to the lat workshop this year!

Deep Neural Networks have many successful applications in the recent past among which there are: objects recognition, language understanding, robotic or car movement and many more. They also grow a lot of public attention which leads to many unrealistic expectations and misunderstandings.

During the workshop we will present a theoretical basis of Deep Neural Networks as well as a simple yet powerful way of creating such networks which will be capable of object and pattern recognition as well as learning from the reinforcement feedback.

All algorithms will be explained so that the participants can easily understand what are the basics of the artificial neural network and what are the main challenges during the development.

We recommend that participants should have a basic knowledge of Python programming. Workshop will take lace June 10-12th. The deadline for application is May 30th, application form can be found here.

Workshops will start 10 AM and last till 6 PM.

Ephys and optogenetics workshop, April 24 – 26th

We have pleasure to announce the next Nencki Open Lab Workshop!

This time you will have an oportunity to learn about electrophysiological recordings and optogenetics. During the workshop we will go from basics (neuron biophysics, ion channels the design of the ephys setup) to practicals – building tetrodes and optic cannulas, using Arduino to control your optogenetic stimulation protocols, ephys data analysis and intepretation. We will discuss how to synchronize diffrent data streams and combine your recordings and stimulation with behavioral experiments.

During the workshop you will also have an unique opportunity to discussing your ideas and problems with experts!

Workshop will take place April 24-26th. You can find an application form here .

The cost of the workshop is 50 PLN. The deadline for applications is April 18th.

Braitenberg vehicles and Arduino – how to make a robot

In a now classic book, Valentino Braitenberg described a thought experiment in which, by building simple robots with motors and sensors we can obtain a set of machines exhibiting surprisingly complex behavioural repertoire. Braitenberg vehicles „love” or „hate” objects in their environment, they can learn new things and, to an observer, seem to be really intelligent creatures.

The book shows how complex behaviors can be generated by simple mechanisms and create a great starting point for thinking about animal behavior and the function of the nervous system.

In our next workshop, we will use Arduino to build robots inspired by Braitenberg vehicles. Our machines will search for light or avoid it, will detect obstacles, exhibit „feelings” towards other robots and many more. We will illustrate each of our vehicles with analogous mechanisms that can be found in real living systems, from bacteria to animals.

Beyond that, our workshop will be a great introduction to Arduino robotics. You will learn how to write and organize more complex Arduino code and how to combine many sensors with many effectors in an efficient way, how to use more advanced libraries and communication protocols.

Workshop will take place March 23-24th (weekend), 9AM – 4 PM. Please find the application form here. We wait for applications until March 12th.

We require a basic experience with Arduino programming.

The cost of the workshop is 50 PLN.

Using git for scientific software projects, February 15th

During workshop we will cover all the basic elements of how the code is nowadays managed using the open infrastructure provided by GitHub and the free CI runners. You will learn how to set up a repository so that others can contribute to it by sending pull requests, and to have the pull requests automatically tested.

Plan of the workshop:

– quick introduction to version control using git
– testing scientific code and using CI systems
– the OSS workflow using public code, branches, pull requests, and review

Please find the application form here. We wait for applications until February 11th.
