Hi everyone, if there is an easy way to crop volume into a defined ROI, e.g. 5mm x 5mm x 5mm? The current setting allows for dragging the ROI boundaries. I wonder if we can specify the volume we need and drag the ROI location instead?

You can specify the dimensions of the ROI as I did in the screenshot below, and then use the middle handle (orange one) to drag it wherever you want.

You may want to disable to scaling and rotation interactions during the move to avoid the issue of acciendetally changing the dimensions…

This is exactly what I was looking for. Thank you so much! I was trying to find it from the crop volume module. 3Dslicer is great but sometimes you have to know where one feature might be hidden.
