Hi Ayla,

Thank you for getting back to me. The version you refer me to is the current version that I have installed on my Windows computer. I suspect that I am having issues with some filters because the development libraries are 32 bit. Just to be clear, I don’t have trouble loading in large datasets into Seg3D (I’ve tried up to 13 gigs). It’s when it comes to applying filters that the program crashes. Do I have to build from scratch on my Windows machine in order to ensure that the development libraries behave for large datasets?


I found some information about this here:


Specifically, the section that states:



A Visual Studio binary build is available. To our knowledge the Windows Visual Studio development libraries are only available in a 32-bit version. A 64-bit version can be built from the source code download, configuring it as described on the Qt webpage.

Do you happen to already have a version that fixes this problem, or could you provide me with the Qt webpage i.e. a set of instructions to build this myself? Thank you!

Hi Katie,


You can download a 64-bit Windows build from

Good afternoon,


I’m having issues with using the Otsu filter on my 64 bit Windows 7 machine. Every time I try to use it, Seg3D crashes. I believe it has to do with the large dataset I’m using (3.3 GB) and the development libraries only being 32 bit. Do you happen to have an already compiled version for 64 bit windows, or could you please provide me with a place where I can find instructions to build a 64 bit version?


Thanks so much,

Katie Matusik
