import .voi file into matlab

Hi

I was given an .voi file 3D, file attached fyi. It was generated via a segmentation tool and the roi was given by each slice and a serial of pixel coordinates. Never seen this before so just wondeirng anyone knows a good way to import this file? I was hoping to get a 3D BW mask from this file.

Many thanks in advance!

Hi,

I don’t think there is a direct command for importing .voi file in MATLAB. You can see the list of supported file formats for Import and Export operations in the link provided below:

https://www.mathworks.com/help/matlab/import_export/supported-file-formats.html

But I found implementation of some ways to perform this operation on file exchange. These implementations will help in extracting a sub volume of interest from a given volume of interest. Please refer to following links for some information: https://www.mathworks.com/matlabcentral/fileexchange/47295-voi-extraction-from-a-3d-dataset

Hope this helps!
