    Hi everyone,

    I repeate DTI measurement for four times and I've used the AIR registration tool provided in the DTI Studio to co-register the four datasets in the DICOM format from Siemens. However, it seems the tensor calculation is still done on the datasets without registration. Just wonder how we can tell the DTI Studio to work on the registered datasets. Any suggestion will be greatly appreciated!

    I've figured it out. When you click the "Automatic Image Registration" button to co-register the DTI series, please make sure to check off the option "Create new images after registration" so that DTI Studio will work on the registered DTI raw images during the later tensor calculation. DTI Studio is pretty handy. Many thanks!

    in the AIR-parameter dialog within DtiStudio, there is an option "create new images after AIR". if this option is unchecked, the AIRed images will overwrite the original images (in the memory, not the file). then, the tensor calculation will be carried out using AIRed images.

    if this option is enabled, the AIRed results will be created as new images. the program will still use the original for tensor calcuaton. the AIRed images can be resaved as new files for later usage.
