Synopsis
mri_normalize <input directory> <output directory>
Arguments
Positional Arguments
<input directory> |
input directory |
<output directory> |
output directory |
Required Flagged Arguments
none
Optional Flagged Arguments
-no1d |
disable 1d normalization |
-conform |
interpolate and embed volume to be 256^3 |
-gentle |
perform kinder gentler normalization |
-f <path to file> |
use control points file (usually control.dat) |
-w <mri_vol c> <mri_vol b> |
write ctrl point(c) and bias field(b) volumes |
-a <float a> |
use control point with intensity a above target (default=25.0) |
-b <float b> |
use control point with intensity b below target (default=10.0) |
-g <float g> |
use max intensity/mm gradient g (default=1.000) |
-v |
verbose |
-n <int n> |
use n 3d normalization iterations (default=2) |
-u |
print usage |
-prune <boolean> |
turn pruning of control points on/off (default=off). Useful if white is expanding into gm |
Outputs
wm |
wm volume of the cortical reconstruction is used as the input for mri_fill |
Description
["mri_normalize"] converts orig or nu volume from cortical reconstruction as input into a new volume where white matter image values all range around 110
Examples
Example 1
mri_normalize SUBJECT/mri/nu SUBJECT/mri/wm
Uses the nu volume (nonuniformity corrected volume), and creates the wm volume, with white matter voxels around 110 image value
