Here are some of the features we have been developing to make it easy to build panoramas, pick regions-of-interest, and to visualize ROI location and data during acquisition using the NLW Mesoscope (aka the Kraken) on the latest version of Scanbox. The video below shows a brief demo of the following: The automatic creation of…
Read MoreSome time ago we talked about the advantages of synchronizing the digitizer sample clock to the laser. Our new system incorporates an on-board PLL multi-phase clock that allows Scanbox to automatically measure the contrast in a test image as a function of sample phase delay and select the optimal value for your setup. A typical measurement…
Read MoreUpdate[6/1/2018]: Please update Scanbox to make this feature work correctly. An error in the code of earlier versions incorrectly set the gain for fixed-type amplifiers (variable type amplifiers were handled correctly). An alternative, easy way to fix the issue without having to update Scanbox is to search for the constant INPUT_RANGE_PM_1V in scanbox.m and replace…
Read MoreThe Neurolabware mesoscope is up and running using our new tower system and today we took it for our first test drive with a tetO mouse. Here is the very first movie sequence of a large FOV with single-cell resolution. We can also build a panorama of a large region using Lissajous scanning (other…
Read MoreSome colleagues have asked about the possibility of integrating imaging acquisition from the port camera to do intrinsic and/or epi-fluorescence imaging ahead of targeting a region of interest with two-photon experiments in Scanbox. We have now added this option to Scanbox. To use this option you will need to wire the I2C port on the…
Read MoreNot long ago I mentioned Scanbox’s new ability to sample on a surface. Now you can access this new feature in the GUI by navigating to the Surface Sampling panel. Surface sampling allows you to link lines of the resonant scan to depths determined by the optotune setting. In other words, it allows you to…
Read MoreKnobby scheduler allows the user to move the microscope by specifying a list of relative changes in position at given frame numbers. One quick way to fill up the table is provided by a set of text fields in the knobby panel. This allows one to perform (x,y,z) tiling with a given range and step…
Read MoreMultiple users of the scope may be running projects that require different types of objectives. How to keep a spatial calibration for each and switch between them when necessary? Scanbox now includes an “objective” configuration variable — a cell array of strings each with the name of a different objective. Right now I have: Now,…
Read MoreDuring volumetric imaging, Scanbox displays all images as they are acquired. This can be inconvenient if we are trying to visually assess the activity of neurons within any one optical slice. One solution is to display the images separately in a montage by means of a Scanbox plug-in. However, it would be better to have…
Read MoreA new checkbox within the Laser panel (labeled AGC) allows you to turn an automatic control of laser power on and off. When AGC is on, Scanbox checks the distribution of pixel values on the image every T seconds, and increases or decreases the laser power by a certain factor if the fraction of pixels…
