> ​Hello all,
>
> I recently have started to figure out how to use imageJ to analyze the uCT
> scans of bone geometry. The size of raw file is quite large, which is about
> 16GB. Because of lare size of the file, it gives me an error with memory
> issue. So what I have tried next is to open up file by specifying the range
> of images. The size of file is 2048x2048; 2016 planes. It shows me an image
> when I have selected 1(Z begin)-250(Z End) with 1 for Z step. The problem
> arise when I have tried to select beyond 250 and it gives me following
> messages.

> The file I am opening is ct.img.hdr file and this scan was done by inveon
> uCT scan. The disc image file (.ct) is ~16GB
