[Mrtrix-discussion] patch for DICOM mosaics

[Donald Tournier]

Hi everyone,

Here is a patch to fix occasional slice-ordering issues when loading
DICOM mosaic images. The images would sometimes be loaded upside-down,
due to my complete ignorance of Siemens' obscure 'SliceNormalVector'
CSA entry in the image headers (thanks to the SPM5 code for pointing
me in right direction...). Note that this problem really shouldn't
affect anything else: if you haven't had this problem yet, there is
nothing to worry about. You might want to wait until the next release
of MRtrix which will contain this fix anyway.

To apply the patch, simply unpack the files into the MRtrix code
folder - this should overwrite the 3 modified files. You should then
issue the ./build command and install as normal. In other words,
assuming you have already downloaded the patch file into the
mrtrix-0.2.5/ folder:

> cd mrtrix-0.2.5/
> tar xfjv mrtrix-0.2.5_dicom_mosaic_patch_2008-09-05.tar.bz2
> ./build

and copy over into your final installation folder as you would normally.

Regards,

Donald.
