Hi,
I'm trying to use mri_label2voxel to produce an image of a segmented region in the original image voxel space and am seeing black lines through the output region, these are oriented parallel to the voxel axes. In the attached image you can see three of them: two parallel horizontal lines and one vertical one just cutting through the right hand side of the region. This appears to be some kind of aliasing artefact; if I move all the labels by adding 0.2 to each of the location values in the labels file then the lines are shifted to different voxels (not the immediately adjacent ones). Using the 1mm^3 voxel registered volume as the template does not show this problem, neither does viewing the label overlaid on orig.mgz in tkmedit. Is there anything I can adjust to avoid this while still outputting a volume in the original image dimensions?
Thanks, Ian Malone
