usage: sct_dmri_compute_dti -i <file> -bval <file> -bvec <file> [-h]
                            [-method {standard,restore}] [-evecs {0,1}]
                            [-m <file>] [-o <str>] [-v <int>]

MANDATORY ARGMENTS

-i

Input 4d file. Example: dmri.nii.gz

-bval

Bvals file. Example: bvals.txt

-bvec

OPTIONAL ARGUMENTS

-method

Possible choices: standard, restore

Type of method to calculate the diffusion tensor:

-evecs

Possible choices: 0, 1

Output tensor eigenvectors and eigenvalues.

Default: 0

-m

Mask used to compute DTI in for faster processing. Example: mask.nii.gz

-o

Output prefix.

Default: “dti_”

-v

Possible choices: 0, 1, 2

Verbosity. 0: Display only errors/warnings, 1: Errors/warnings + info messages, 2: Debug mode

Default: 1
