ROI

Postby Ursul » Fri Jun 23, 2017 2:11 am

Hi,

I am trying to draw a cube-like ROI of 5mm isotropic using the "ROI/Add ROI" tool in mango and then checking the "Cube" box and entering 5mm of width. But somehow my ROI mask is only 4 mm in the z direction, while it is 5 mm in the other directions. The voxel size of my images is 1mm isotropic so I do not understand why it is doing so in the z direction. Do you have any idea of what could be wrong here?

Thanks in advance,

Best,
Ursul

Looks like it's some roundoff error with odd number sizes. I'll get this fixed in the next release.

We have a beta site. I'll try to add this fix and post a beta version to test sometime this week. No definite date on the release.
