Software for microscope control
Fast 4D Volumetric Scan
Two software tools are provided for fast 4D volumentric scans in Light sheet fluorescence microscopy. The first one creates a lookup table of light sheet position v.s. focus by performing an autofocus routine at each light position. The second one uses the lookup table and performs the high-speed volumetric scan. Each volumetric scan takes one second total, of two colors, which makes the videos of one frame per second in 4D.

We switched from Micro-Manager to MatLab, and this is the latest volume scan software.
DualAxisMirror.jar ver 1.1 (64-bit Windows) (2/28/2017)
This plugin controls two-axis mirrors for applications like spinning TIRF or ring TIRF in Micro-Manager 1.4.
- Maps mirror coordinates to image coordinates.
- Allows users to define circles with arbitrary centers and radii and submit them to National Instrument boards.
- Synchronizes drawing circles in multiple channels with camera shutter if the NI board supports external triggers.
Note: To install just copy the .jar file to C:\Program Files\Micro-Manager-1.4\mmplugins
This is a Micro-Manager plugin that allows user to adjust voltages over Optoune electrically tunable lens to change its focal distance.
To use this plugin, one needs to add an “UserDefinedStateDevice” in MM for the ETL and
- Change the “Command Mode” setting to “Binary”.
- Change the “Port” setting to the port that ETL connects to.
This is a script used in Micro-Manager for multiple-channel manipulation.
Script is also hosted on GitHub.

Image Surfer (tutorials)
ImageSurfer is a software application used to view stacks of grayscale images, taken from a confocal microscope, as volumes. The user may choose different views–each offering a different interpretation of the data. In turn, the user may interact with the data as a three-dimensional volume or surface.
This version allows users to set a threshold on particle size to filter out undesired particles found in auto-find, e.g. aggregated beads. The area value associated with each particle is added in a new column in the output .csv file.
Bio-formats support has been added since v08.10.
The Video Spot Tracker program is used to track the motion of one or more spots in a set of image files, a video file, from a Microsoft DirectShow-compatible camera, or from some scientific cameras.
See the Video Spot Tracker manual for more information about the program. There are four tutorials available online:

Microscope Simulator enables a scientist to simulate what a given 3D scene should look like under a fluorescence microscope. 3D scenes can be constructed from primitives or imported files in VTK, OBJ, or PLY format. Once a 3D model has been created, you can provide the point spread function (PSF) for a given fluorescence microscope and view simulated fluorescence images. Check out the tutorial.
The Microscope Simulator features an intuitive user interface and a multi-fluorophore optimization algorithm in the FluoroSim module.
The Microscope Simulator enables a scientist to simulate what a given 3D scene should look like under a fluorescence microscope or an atomic force microscope (AFM). 3D scenes can be constructed from primitives or imported files in VTK, OBJ, PLY, or UNCA format. Once a 3D model has been created, you can provide the point spread function (PSF) for a given fluorescence microscope and view simulated fluorescence images. In addition, you can specify the parameters of a simple AFM tip model and quicky generate a simulated AFM surface scan.
See the Microscope Simulator web page for more instructions on using the program. A tutorial is available online.
ImageTracker is a motion analysis application specifically designed for video microscopy. ImageTracker can stabilize image sequences with respect to moving objects, remove the effect of stationary components from bright field images, and compute and visualize dense displacement fields that explain motion in image sequences (optical flow). New in ImageTracker 3.0 is the ability to apply numerous image filters as well as an improved multi-resolution optical flow implementation.
The CISMM Video Optimizer provides contrast and gain control, cropping, and point-based image stabilization on stacks of TIFF files and video files. It also enables simplified background subtraction and the accumulation of minimum, maximum, and average video frames.
The CISMM Template-Based Matching program is designed to locate and identify objects within Scanned-Probe Microscope images and produce a file of descriptive statistics about these objects.
A manual and a tutorial are available online.
Network Extractor is a program for segmenting and collecting statistics on fibrous objects in 3D images. It has been developed with the specific target of fibrin network images in mind, but can be applied to images of any kind of fibrous object such as collagen or actin networks, for example.
PSF Estimator is a program for fitting mathematical models of point-spread functions from microscopes to images of fluorescent beads with diameters below the resolution limit imposed by diffraction. Currently, only PSFs from widefield fluorescence microscopes are supported.
Source code is available here.
The Stereo Spin program is used to display stereo images from a spinning-loop video, making it easy to display stereo content from scientific visualizations or animations that were not originally rendered in stereo. It drives OpenGL stereo hardware if it is available. It can also drive cross-eyed stereo on any computer.

Clarity is an open-source C/C++ library implementing many of the common deconvolution algorithms used in fluorescence microscopy. It is designed specifically for processing 3D images generated from optical sectioning. Clarity uses multithreaded algorithms to make full use of all the cores on modern multi-core computer systems. For even greater performance, the deconvolution algorithms can optionally run on commodity graphics processing units that feature hundreds of computing cores. Support for acceleration on graphics processing units is currently available on NVIDIA graphics cards.
A manual is available online.

The WebSlinger program is used to simulate the deformation of a 2D web of masses connected by springs. The springs can be linear or nonlinear (with specified strain/force curves). The initial rest length and spring constant can be calculated based on the initial positions of the points and an initial strain estimate.
You can interact with the simulation by pulling on individual masses with the mouse. You can also set trajectories for one or more masses and compute the response of the other masses.
The PreAnalysis application will open a vrpn tracker log or a live vrpn tracker connection in order to calculate and display a mean-squared-displacement (MSD) plot.
This program simulates the distribution of DNA in a gel electrophoresis study of Yeast chromatin cut by enzymes. It lets you specify the fraction of nucleosomes that are unwrapped (wrapped ones have inaccessible DNA). It lets you specify the variance in the distribution of nucleosomes around their mean distance. It lets you specify the number of cuts per unit length (enzyme concentration). It plots the effects of these on the log number of base pairs, which matches the gel electrophoresis mass distribution. This provides a way to investigate whether features seen in the distribution are caused by nucleosome unwrapping or by nucleosome position variation.
Camera-calibration program brought to you jointly by CISMM.org and Megawatt Solar, Inc. This tool lets you print out a 2D color pattern that uses red and green to form a grid and blue to identify the grid, so that by selecting a few boundary points and thresholds you can automatically determine the camera’s intrinsic and extrinsic parameters. It uses Tsai’s coplanar method (source code included) to do the calculations once it has selected the points.
