Name
mri_concatenate_lta
Description
Concatenates two consecutive LTA transformations into one overall transformation, Out = LTA2*LTA1
Synopsis
mri_concatenate_lta [options] lta_1 lta_2 lta_final
Arguments
Required Arguments
lta_1 |
maps some src1 to dst1 |
lta_2 |
maps dst1(src2) to dst2 |
lta_final |
the combined LTA maps: src1 to dst2 = LTA2*LTA1 |
Optional Arguments
Flag |
Description |
-tal file1 file2 |
if lta2 is talairach.xfm specify src (file1) and template (file2) for the talairach xfm. |
-invert1 |
invert lta_1 before applying it |
-invert2 |
invert lta_2 before applying it |
-invertout |
invert output lta |
-out_type |
set final LTA type: 0=VOX2VOX (default), 1=RAS2RAS |
-subject subject |
set subject in output lta |
-rmsdiff radius outputfile |
computes RMS diff between transforms using MJ's formula a radius of 70 is suggested. RMS will be saved in outputfile unless outputfile = nofile Eg, mri_concatenate_lta -rmsdiff 70 rms.dat lta1 lta2, note: no output lta |
You can use 'identity.nofile' as the filename for lta2 e.g.: mri_concatenate_lta -invert1 lta1.lta identity.nofile inv1.lta
