Using NI DAQmx in MATLAB

This post is from Rob Campbell:
As part of TENSS we have created a set of examples showing how to use DAQmx in MATLAB without the Data Acquisition Toolbox. This is achieved using…



OpenMV – Fast and easy machine vision

OpenMV is an open source machine vision system. It’s designed to be easy-to-use, with a gentle learning curve. They want this to be the “Arduino of Machine Vision”. The software IDE is free and…



PMT power supply

I was cleaning house a bit, and among my old files I found this, which might be worth sharing. Years ago I made a centralized power supply for a custom 2-photon imaging system I built. There were two epi…



Analysis algorithms: performance quantification and ground truth

We recently tweeted about a preprint from Eftychios A Pnevmatikakis and Andrea Giovannucci (code). The preprint is on motion correction for calcium imaging data. It is a nice quick read and discusses earlier work in the area….



SpikeGadgets extracellular recording and open source software

SpikeGadgets makes hardware and software for extracellular array recording.

They make nice looking hardware, both for recording from arrays, and for controlling experiments.



iPad/iPhone/iOS app RayLab for optical design

RayLab is an iOS app (iPhone/iPad) for optics analysis. It has some nice features– more than I expected. It’s a nice piece of work! For many practical applications it cannot replace conventional optic design software (e.g., Zemax/OSLO/CodeV). That…



ViRMEn – Virtual reality MATLAB engine

Dmitriy Aronov, while postdocing in David Tank’s lab at Princeton, developed a virtual reality engine that runs in MATLAB called ViRMEn. It’s open and there’s a good amount of documentation. The downloadable versions



Slack software for labs

Slack is very useful team coordination software. It’s been such a help in my own lab, that I suspect that given a properly configured Slack account, I could simultaneously run GE, Google, Intel, and the US Federal…



Orange is open software for data exploration

Orange is a user friendly, graphical data mining package built with Python, from the University of Ljubljana. Check it out. They have a good blog for the project too.



moco, fast open-source motion correction for 2-photon calcium imaging movies

Results are similar to the slow version of TurboReg, but it runs about twice as fast as the fast version of TurboReg.

Here’s the paper.
Here’s the code.



Open source structured illumination MATLAB code

Peng Xi (Peking University) shared this resource his lab has developed: software for processing images for structured illumination (a superresolution technique).
Here’s the Github repository.
And here’s the paper (pay wall).

Previously on…



Ufora – easy parallel computing in Python

It’s still early days, but this looks impressively good. Ufora might be one of the easiest-to-try ways to use parallel computing. With just a couple of lines of code, you can run your existing Python…



CANDLE-J for denoising 2p data

Collaborative Approach for eNhanced Denoising under Low-light Excitation, or CANDLE, is a denoising algorithm specialized for the type of images that are acquired in 2-photon imaging applications. There’s code for both ImageJ and MATLAB available at that…



Phase retrieval

Microscopists are often adapting techniques pioneered for astronomy. Adaptive optics is the example you all probably know. Relatedly, phase retrieval was originally developed for telescopic imaging systems, and was adapted for high NA microscopic imaging systems by…



Calcium imaging analysis GUI for MATLAB

Stephan (currently in the Gilbert lab @ Rockefeller) wrote in to share his code for analyzing calcium signalling data in MATLAB. Thanks, Stephan!

Stephan writes…

I made a MATLAB GUI that automatically extracts ROIs from calcium imaging data….
