[Mrtrix-discussion] importing data from seimens machine

[Donald Tournier]

Hi Rakesh,

Yes, the DW directions in Skyra data are stored under a different tag than
they used to. On top of that, if you sent your images out from the Skyra
through a Syngo.Via server, there's a chance the DW directions would have
disappeared from the DICOM headers altogether (we certainly have a few
datasets affected by this). This last problem has since been fixed, but it
could be the reason why you're having trouble.

In any case, I recently submitted a patch to the mailing list (
http://www.nitrc.org/pipermail/mrtrix-discussion/2012-October/000567.html)
which should allow you to handle these new data. Since the text of that
message seems to have mysteriously disappeared from the archives, here are
the instructions on how to install the patch from that message:

*$ cd mrtrix*
*$ tar xvfj mrtrix-0.2.10_DICOM_multiframe_patch.tar.bz2 *
*$ ./build clean*
*$ ./build*
*$ sudo ./build install*


Hope that sorts out the problem.
Cheers,

Donald.
