Hi Shreya,

You don't need to open the data in the 3D viewer for BoneJ's analysis to run and give you a result. Since your images are so big, I'd suggest turning off the 3D rendering options in BoneJ's Particle Analyser.

Experience shows that ImageJ's 3D viewer prefers small volumes, and as far as I'm aware is strongly constrained by the amount of video RAM on your graphics card. So you need a big card (with some GB of VRAM) to open that much data, even with resampling. You can try cropping out empty space and resampling the stack prior to trying to load in the 3D viewer.
