Hi Ayla,

Thanks. On a related note, there's a bug with the NRRD exporter in Seg3D2. It's the same problem as with other formats, lack of precision.

The spacing, offset, etc are exported to the .nrrd file as a number with format


So if you are using microscopy images, or high resolution MRI, for example, and your voxel size is 0.22 um, the values are lost.

A solution would be to use exponential notation with 12 digits of precision


Best regards,
