- Change type to "All Files"
- Select bvals, click Open

The values will appear as one row.

- Select the row of values, and Copy.
- Go to an empty cell (next row down)
- Paste Special,* select Transpose option
* To get to Paste Special, from Home tab in ribbon, click small down-arrow below "Paste", or after pasting, click on Paste options ("Ctr" usually on right).
Create new text file with column-format bvals
- Open Notepad
- Copy the column of bvals (make sure you don't include cells on the top row)
- Paste into Notepad
- Save as bvals4tracula.txt in the same folder as the bvals file
Create bvecs file
Repeat these steps for the bvecs file; the difference is that there are three measure for each volume, so you will be starting with three rows in bvecs, and creating three columns in bvecs4tracula.txt.
