Dear SPM developers,
I came across with a problem when I try to reorient .nii images via
display button with the latest Update 1048. I think this may be a bug,
so I report the problem.
Below is what I did.
1) Dicom files were converted to an Nifti image with Jolinda Smmith's
MRIConvert. Files are stored as a single nii file.
2) An nii image was displayed with "Display" function. SPM5 displays
the image without any problems.
3) I set AC-PC manually and push "Reorient images...", reorienting the image.
4) Then I get into trouble. The graphics window went white only with a
frame and an error message in Matlab says, "Image cannot be
resampled..." "file too small"
5) I checked the file size and saw that now the nii file I tried to
reorient is only 348 bytes, which is the same as usual .hdr files.
That is, nii file with a header and an image (over 20Mbytes) was
replaced with a mere header information and image itself was lost...
So, this must have something to do with handling header information of
nii format.
I checked the following to make sure that this is a problem of
handling nii format and this doesn't happen with previous versions;
A) I prepared Analyze format images (.hdr and .img files) and went
through the same procedure I described above. This time everything
works fine.
B) I re-installed SPM5 in a different directory, and applied Update
958 (the last update). This also worked fine. Nii files were handled
correctly.
Below is my computer environment, (though I think it is not so
important since Update958 works fine with this environment...)
CPU: Athlon64 3800+
OS: openSUSE 10.3 64bit
Matlab: R2007b 7.5.0.338 (64bit)
gcc: 4.2.1
Any advice or proposal would be appreciated.
Best regards and wish you a happy new year!
