[Mrtrix-discussion] BASIC question on importing data

[Ivan Alvarez]

Hi Alessandro,

Have a look here: 
http://www.brain.org.au/software/mrtrix/faq.html#FSLencoding

Ideally you should extract your gradient table from the original DICOM 
files. Failing that, if your acquisition was in real axial orientation, 
you can copy-paste your text-files so they look like this: 
http://www.brain.org.au/software/mrtrix/tractography/dwi.html#dwscheme

and then feed that file to subsequent commands using the *-grad* flag.
