[Gate-users] Dose actor voxel precision issue

[Matthew Strugari]

Hi all,

When using the dose actor with sub-mm voxels, I notice issues with the floating point precision of the Offset and ElementSpacing stored in the output mhd files:
Offset = -25.440999999999999 -25.440999999999999 -26.25
ElementSpacing = 0.49399998784065247 0.49399998784065247 1.5
Which are based on my settings:
/gate/actor/dose1/setSize 50.882 50.882 52.5 mm
/gate/actor/dose1/setVoxelSize 0.494 0.494 1.5 mm

I have been ignoring this and manually overwriting the header files since the difference is insignificant but it would be nice to avoid having to do that. Has anyone else experienced this issue?

Cheers,

Matthew
