Hi Guang,
I cc'd the freesuefer list as this is where the expert are... :). I do not think that I fully understand what you want to achieve here, so bear with me as my response might be really really daft. In that case I really recommend to bring this onto the experts on the freesurfer list... I guess my first question is: How did you get the niftii files in the first place? It looks like the tool you used there did have some differences in say the origin. Now, I am no expert, but I would go and register and reslice the volumes, taking your niftii as target (otherwise switch arguments), make sure the volumes are in the current directory or adjust the pathes:
tkregister2 --targ nu_C1NC0.mgz --mov nu_fs.mgz --regheader --reg nu_fs_2_nu_C1NC0.register.dat and then reslice:
mri_vol2vol --mov nu_fs.mgz --targ nu_fs.mgz --o nu_fs_C1NC0space.mgz --reg nu_fs_2_nu_C1NC0.register.dat
that should give you the freesurfer NU in C1NC0 space. If you want the whole surface recon in freesurfer in C1NC0 space you probably should do this registration with the initial volume you feed into freesurfer so that all following steps are already in the correct space.
I hope that helps Sebastian

Hello, Sebastian,
I hope I explained my question clearly, I attached the mri_info of these two mgz files. I noticed that there are few differences such as c_r, c_a and c_s. But why there are different? Oh maybe I need ask how could I make them the same?
Sorry, ask you so many questions.

Hello, Sebastian,
Sorry to bother you again, I got a question about mri_convert now,
I have a subject in dicom format, I convert it to NIfTI format. Then I convert both of them to mgz format, using mri_convert -- conform.
I thought they should look as the same, but actually they are not at all. Do you meet this kind of problem before? Does mri_convert treat dicom and NIfTI differently?
Thanks a lot!
Guang Zeng

Hi Guang,
always happy to help :)...

Hello, Sebastian,
Thanks a lot for your help yesterday about that "redraw fails" problem, it works on my machine now. However, I also noticed that although the tksurfer is working well now, that "redraw fails, no gl window open" message is still there.
Well, I have no real idea, except I recall that I saw these messages as well but always ignored them if tksurfer worked. Oh make sure you have "export doublebufferflag=1" in your bashrc, that often
convinces
tksurfer to use doublebuffering even if tksurfer thinks your
computer
can not do this.
Anyway, I am very glad that I can use tksurfer now, it bothers me for two weeks.
Glad I could help...
ahoi & regards Sebastian

hi Guang,
Have a look at this:
ERROR: ld.so: object '/home/m047599/freesurfer-install/
freesurferbin/
libGL.so.1' from LD_PRELOAD cannot be preloaded: ignored.
I guess there is a missing a "/" in the LD_PRELOAD line. Try:
setenv LD_PRELOAD ${FREESURFER_HOME}/bin/libGL.so.1 NOTE the extra "/" between ${FREESURFER_HOME} and bin. That
should
fix
this part of the problem, but whetheer it fixes tksurfer I do
not
know...
hope this helps Sebastian

Hi Guang,
let me send you the attachement again. This contains redhat
server 4
GL libraries that have to be unpacked in $FREESURFER_HOME/
bin.
The
system we use it on only has a lowly ATI card without
proper 3D
support, so I think MESA is installed there and we use
nomachine's
NX
client to access the server over the network, which works
nicely and
displays the full surfaces. Unfortunately since I
responded to
your
post other people tried my proposed solution and failed,
so I am
unsure whether it will help in your case...
good luck Sebastian
