We are starting to research Tractragraphy for 3d printing purposes and struggling to get the process started with our images. We have loaded all of our dwi images but run into a problem with the brain masking program returning an error saying we have no b0. We do indeed have a b0 in these files but something is getting lost. Is someone able to take a look at my files to help guide us back on tract?
Update. My files contain a Multivolume, each direction as a separate scalar, and a DWI volume. Exploring the metadata shows there is more then one b0 and the rest are showing as b800. When loaded and exploring the node information I see a ton of data. However, when I explore the sample data, it reflects a very clear b0 and subsequent set of coordinates for each image. So something with my data is not translating. Any guidance is welcome.
Can I suggest you try converting these images with dcm2niix. You could either run this directly from the command line, or you could install the Slicer Extension (select the View/ExtensionManager menu item and search for “SlicerDcm2nii”). Each vendor has their own method for storing gradient information in a DICOM, and each vendor has changed their storage over the years. Therefore, using a different conversion tool may help.
That worked! Thank you.
