Hi Bruce,

Thanks for your email. Just to make sure: the original voxel size is 0.35 um isotropic. so in my case, the scale bar would be 3.5 mm, right?

Thanks, Reza

it should be, unless you've "fooled" mri_convert into thinking the voxel dimensions are different than what they are, which is a standard trick with the monkey data. In that case its 10 of whatever your original voxel dimensions were.

cheers, Bruce

Hi,

Does anybody have any idea what the scale bar shows in Tksurfer? I have heard that the scalebar is 10mm for the human brain. I am working with the monkey brain. Is the length of the scale bar 1cm for the monkey brain as well?

Thanks, Reza
