 The first thing to do is get your data into TORTOISE. ​ You can import a variety of data formats (Phillips PAR/REC, DICOM, NIFTI, and Bruker). ​ I highly recommend importing from either DICOM or FSL NIFTI. ​ If you choose DICOM, you will need to supply TORTOISE with your gradient file, as it will not read the directions from your DICOM headers. ​ If you choose FSL NIFTI, TORTOISE will read your bvec and bval files from text, they just need to have the name (bvec or bval) in the filename and be in the same folder as the NIFTI file.  TORTOISE will search sub-folders for these files, so if you have multiple bvec or bval files in your folder or sub-folders,​ it will give you an error that it found multiple bvec/bval files and you’ll have to tidy up your file structure. The first thing to do is get your data into TORTOISE. ​ You can import a variety of data formats (Phillips PAR/REC, DICOM, NIFTI, and Bruker). ​ I highly recommend importing from either DICOM or FSL NIFTI. ​ If you choose DICOM, you will need to supply TORTOISE with your gradient file, as it will not read the directions from your DICOM headers. ​ If you choose FSL NIFTI, TORTOISE will read your bvec and bval files from text, they just need to have the name (bvec or bval) in the filename and be in the same folder as the NIFTI file.  TORTOISE will search sub-folders for these files, so if you have multiple bvec or bval files in your folder or sub-folders,​ it will give you an error that it found multiple bvec/bval files and you’ll have to tidy up your file structure.
