Hi all,
I got some problems when I tried to overlay some maps one brain surface. The following steps is just for test.
1. recon-all -all -notalairach -i MP-rage/001.dcm s test 2. I use matlab to load the save dataset (MP-rage/001.dcm ~ 160.dcm) and then mark the back-head (>1000). The output is test_mark.img (analyze format) 3. thregister2 --targ ./test/mri/orig/001.mgz --mov test_mark.img regheader reg reg.dat So I got reg.dat in this step 4. thsurfer test lh inflated --overlay test_mark.img overlay-reg reg.dat fthresh 1000 The weird thing happened in the final surface image. The mark is not shown in back-head. It is located in the botton of the brain surface. If in the 4, I do the following instead (no registration) thsurfer test lh inflated --overlay test_mark.img --fthresh 1000 The mark is in the right location (back-head), but a little offset.
Whats wrong in my procedure? Am I doing right in the registion part? Is it correct to register to /mri/orig/001.mgz?
Thanks! Elva
