3.2.11.1 Export to FSL

Export Data in FSL-like format

  1. Start up DIFF_CALC according to the software guide.
  2. Click on load listfile, and navigate to your list file (if you have run the registration software, this will be the one ending in _DMC.list)
  3. A window may pop up asking about Endianism, select "statistical test" and click Done (unless you know what the endianism is, then you can specify big or little and click done).
  4. Click on the "export images" button on the left hand side of the GUI that has become active. For FSL: Select the "RAW FSL-LIKE UNSORTED". This may take a few minutes to finish, depending on how big your data is. It will create a bvecs, bvals and a 4D analyze file (.img/.hdr). The following message will be displayed when it is finished: "Raw images exported. 4Ddata UNSORTED bvecs, Flipped X". Similarly, for Camino: Select either the "RAW FSL-LIKE SORTED" or the "RAW FSL-LIKE UNSORTED" option depending on your desired scheme file version.
  5. You're done. Just click the "quit" button in the GUI to close the software. There will now be a new directory inside your proc directory ending in _FSL_RAW_UNSORTED (or _FSL_RAW_SORTED). If you go into that directory, you will see the files you need for running FSL or importing into Camino.

Notes

  • The statement "Flipped X" reflects a simple difference in coordinate system between our software and FSL and Camino.
  • If you need a mask image, use the mask raw images option of DIFF_CALC before selecting export images. The mask that is created here will be output to the same _FSL_RAW_UNSORTED directory.
