HI Bruce,
Ok, great. I just thought some sections of white matter had not been traced in their entirety (see red crosshair in attached image). If you think this all looks reasonable, please can you advise on the misaligned as outlined in the original post?
Best wishes,
Mason

Hi again Bruce,
I have now installed the relevant libpng packages and have freeview open. The segmentation doesn?t look brilliant in some areas. What do you think?

Hello Freesurfer developers,
I am using Freesurfer and SamSrf for prf mapping. I have ran the recon-all
command which finished without errors. However, the white/grey matter
boundaries are significantly misaligned with the subjects T1 (images
attached). Below are the steps I have taken to reach this point in the
analysis:
1. Run fsl_anat to get a bias corrected T1 and T1_biascor_brain.
2. Ran Feat
? Distortion correction of the EPI
? Motion correction
? No smoothing
? Highpass filter
? No registration to whole brain
? Register to T1_biascorr_brain
? Register to standard space
3. Ran recon-all on T1_biascorr
4. Convert T1/T1_brain/orig(001) from mgz to nii
5. Check registration (using the SurfaceProjection command from the SamSrf
package) which leads to the attached images named S1 and S1.
Freesurfer version:
freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c
Platform: Linux 5.3.0-40-generic x86_64
Uname: Linux masontwells-VIG800S 5.3.0-40-generic #32~18.04.1-Ubuntu SMP Mon
Feb 3 14:05:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
As you can see, the registration is significantly misaligned.
Can anyone offer any advice on this/suggest a way to rectify it?
Thanks in advance,
Mason

I think the problem is not with running the version he downloaded, but the fact that he could not download it, because all download links on the website at https://surfer.nmr.mgh.harvard.edu/fswiki/mri_deface are dead.
I downloaded mri_deface from that website about a month ago, back then the links were still okay. It seems something went wrong on the server in the meantime.

Hi everyone,
I am confused by the two types of registration files: .lta and .dat.
.dat file is simpler and easier to understand. But for the .lta files,
there seems to be no detailed explanation regarding it. Can anyone point
out to me where can I find the detail explanation of the file? And, what's
the relationship between .lta and .dat file?
Also, .lta files seem to cause some compatibility issues. For example, if I
use the tkregister2 utility to make some changes to the registration file
of type .lta (generated by bbregister), like below
tkregister2 --mov $someSeries --reg
$SUBJECTS_DIR/$subjectid/mri/transforms/FLAIR.auto.lta --surf pial
and save it from the GUI, then many errors occur in the console window,
like below:
......
MatrixAsciiReadFrom: could not scanf parms
ERROR: TransformLTA2RegDat(): type = 2011264000, must be 1 or 0 or 14
Segmentation fault (core dumped)
Actually that is because the registration file has been saved in the format
of .dat, although the file extension is still .lta, and the tkregister2
program finally cracks when reading the newly saved .lta file.
Anyone can solve my confusion? Thank you!

Dear FreeSurfer team,
I am currently using FreeView v3.0, Darwin Build Mar 25 2020 00:009:39
Would it be possible to add the following features as command line flags to FreeView?
1) Set opacity for a surface
It is currently only possible via CLI to set opacity for volumes, surface overlays, and labels, but not for the surface itself.
2) Set smoothing iterations for isosurfaces
This can only be done in the GUI, not yet via the CLI.
Thank you for your consideration.

Hi Javier
no, that's not correct, depending on which training set you mean. For the
Bayesian segmentation (aseg) we used 40 datasets distributed in age and
pathology (10 each for young, middle age, elderly and AD).

I can not open the power point for some reason. Is there any paper where I

people, is this correct?

HI Bruce,
Ok, great. I just thought some sections of white matter had not been traced in their entirety (see red crosshair in attached image). If you think this all looks reasonable, please can you advise on the misaligned as outlined in the original post?

Hello Freesurfer developers,
I am using Freesurfer and SamSrf for prf mapping. I have ran the recon-all
command which finished without errors. However, the white/grey matter
boundaries are significantly misaligned with the subjects T1 (images
attached). Below are the steps I have taken to reach this point in the
analysis:
1. Run fsl_anat to get a bias corrected T1 and T1_biascor_brain.
2. Ran Feat
? Distortion correction of the EPI
? Motion correction
? No smoothing
? Highpass filter
? No registration to whole brain
? Register to T1_biascorr_brain
? Register to standard space
3. Ran recon-all on T1_biascorr
4. Convert T1/T1_brain/orig(001) from mgz to nii
5. Check registration (using the SurfaceProjection command from the SamSrf
package) which leads to the attached images named S1 and S1.
Freesurfer version:
freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c
Platform: Linux 5.3.0-40-generic x86_64

Feb 3 14:05:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
As you can see, the registration is significantly misaligned.
Can anyone offer any advice on this/suggest a way to rectify it?
Thanks in advance,
Mason

Hi Javier
no, that's not correct, depending on which training set you mean. For the
Bayesian segmentation (aseg) we used 40 datasets distributed in age and
pathology (10 each for young, middle age, elderly and AD).

not sure we can help if everything looks good in freeview. Doesn't that
