Scanbox has a memory mapped mechanism to share the incoming data stream with other processes that intend to consume the data in real-time. Examples of simple uses of such data sharing include the calculation of rolling averages, displaying a real-time histogram, or generating a montage display for volumetric data. Of course, different experiments may need…

New alignment and segmentation tools
Improved alignment and segmentation tools have now been released in the latest version of Scanbox, while retaining much of the functionality of the last version. sbxaligntool. The new alignment tool, shown below, adds batch processing of files, including the processing of eye and ball motion if those data are present. A region-of-interest (ROI) can optionally be…

Spikefinder: the Vanilla algorithm
Over the last few months, the Spikefinder challenge has provided a playing ground for colleagues to offer ideas about how to estimate the spiking of individual neurons based on the measured activity of fluorescent calcium indicators. The challenge was for people to come up with strategies that beat the performance of state-of-the-art algorithms, STM & oopsi. A good number of algorithms were able…
Read MoreExternal TTL trigger
To automatically start /stop acquisition by means of an external TTL signal follow the following instructions. First, connect an appropriate TTL control signal to the P1.6 (pin #21) of the extension header of the Scanbox board. The view below shows a top view of the Scanbox control board. The pin in question is located on…
