RE: Voxel data greater than 255

Hi Mohan,

While I know little about the matlab code, maybe you need to properly
specify the type of data you are reading/writing, whether it is bytes, shorts,
ints or floats, for example. Maybe the type is considered byte, if you have
not otherwise specified it.

RE: UID in Nifti File

Richard Reynolds — Tue, 20 Mar 2012 16:18:50 GMT

Hi Vanessa,

Whether that UID is for the subject or the user of the software, there is no
explicit field for it in NIfTI. Such information might fit into a GIfTI header
(surface data format), but the NIfTI format is pretty tight, being based on
ANALYZE.

Also, in light of most users wanting data to be anonymous, such a field might
not be well used.

UID in Nifti File

vsochat — Sat, 15 Oct 2011 20:16:29 GMT

Hi,

Does nifti not store any sort of UID from the original image file? I don't see it in any of the header fields.

Many thanks!

Voxel data greater than 255

Mohan Boddu — Thu, 01 Sep 2011 15:13:32 GMT

Hello,

I am using nifti matlab tools. I have used load_nifti.m and save_nifti.m files. When I trying to save a nifti image where the data is more than 255, I am not getting the correct output but when I am doing modulo of the data with 255 then I can see the ouput. But I want correct label numbers not the modulo numbers. Could any one please help me out.

Thank you,
Mohan Boddu
