Hi,
Just trying to understand how FSLView decides on the default
(brightness) window. Is there anything to do with scl_slope and
scl_inter?
Asking, because with some nii I get:
- three whole-white ortho views;
- brightness Min and Max that are completely outside the range of pixel
values in the nii.
No major issue here, because once I change the 'Min' and 'Max' manually
to the min and the max, voila the whole-whites disappear and I get the
expected display. The min and the max I input are consistent with:
- the output from 'fslstats -R';
- the output from Image Histogram.
These pixel values are without linear remapping using scl_slope and
scl_inter. (Which I understand to be correct, as the scl_slope and
scl_inter values in the file are aberrations from dicom-to-nii
conversion, which is a separate matter).
Wondering how come a different set of min-max is used for the default
window.
Thanks,
mary
