Usage: @T1scale <-T1 T1vol> <-PD PDvol>
Fix bias field shading in T1 by scaling it with PD image.
You can also get a decent result even without the PD volume.
-T1 T1vol: The T1 volume
-PD PDvol: The PD volume (aligned to T1)
-odir ODIR: Directory where output gets dumped.
Default is T1scale/
ODIR will contain multiple volumes with the one
of most interest being T1.uni+orig
Script will reuse existing volumes
-align: Align PD volume to T1. Script assumes volumes are in
close alignment. With this option, output PD+orig volume
will be in alignment with T1+orig.
Without this option, PDvol is assumed in alignment with T1vol
-mask MVOL: Create mask for the output
If not specified, the script will generate one with
3dAutomask on fattened PDvol.
-head_mask: Create mask using 3dSkullStrip's -head option.
-unmasked_uni: Do not apply masking to uniformized volume (default)
You can mask the output after you decide which mask
is best. Here is an example with smask:
3dcalc -a T1.uni+orig. -b smask+orig. \
-expr 'step(b)*a' -prefix T1.uni.m
-masked_uni: Apply masking to uniformized volume
-echo: Set echo
