Hi pals!

I've been trying to import large video files >4GB of calcium imaging created in Nikon's proprietary format. I only seem to be able to open the first image in the series via plot function. What I would like to do is open the video and be able to play it within the figure. I have previously been able to export to .avi and play it that way, but I lose all the associated metadata of the file. How would I be able to do this and maintain all the info?

Hi Douglas,

Have you tried using one of the following?

Indeed, however, the file format is .nd2 which wouldn't be compatible with the videoreader.

I don't believe MATLAB provides any documented function for importing nd2 file formats. There is a file exchange submission which can be worth trying. It mentions about supporting nd2 formats, but has not been updated in a while.

It also references the original source, which might have an up-to-date code.
