[Freesurfer] Synthsr command !

[Martin Juneja]

External Email - Use Caution

Dear Juan and FreeSurfer developers,

I am trying to run the *mri_synthsr *command on a MacPro M2 Max chip (OS
13.6.4) - but somehow, I am getting the following error when I try to run
this command. I am using FreeSurfer's 7.4.1 version.

*Illegal instruction: 4*


I would greatly appreciate any help in getting this resolved.



Thanks.

[Freesurfer] [TRACULA] how to setup with opposite phase-encoding

[Fahad Hannan]

External Email - Use Caution

Hi,

I've been trying to use TRACULA on my data, trying to setup a configuration 
file but I am having some difficulty on how to incorporate my data.

I have a DWI scan with 65 volumes (1 b0 image, 64 with b = 1000)
I also have separate volumes for b0 pairs having opposite phase-encoding 
directions.

I am not sure how to incorporate these into the configuration file. I can do it 
with using just the one b0 image, but I'd like to use the opposite 
phase-encoding as well.

How would I go about this in the configuration file?

Thanks,
Fahad Hannan

Re: [Freesurfer] Calculation of MRI intensity

[Douglas N. Greve]

you will have to binarize it first, eg, mri_binarize --i inputimage.mgz

Re: [Freesurfer] T1 maps longitudinal data

Currently, you'd have to convert them  to  t1-weighted images and then

you go the t1 maps from an mp2rage scan

Re: [Freesurfer] Freesurfer Intensity representation

[Douglas N. Greve]

See this tutorial 
https://surfer.nmr.mgh.harvard.edu/fswiki/MultiModalTutorialV6.0 on 
multimodal integration. Basically, you will need to run mri_vol2vol to 
map your MPF volume to the anatomical/conformed space, then run 
mri_segstats passing it the segmentation you want to use and the 
converted MPF image.


On 1/24/2024 11:04 AM, ERNEST KISSI wrote:


External Email - Use Caution

When MPF images are registered on T1 images, I think the intensity 
represents the MPF values, not the T1 values. This is because the 
registration process only transforms the spatial coordinates of the 
MPF images to match the T1 images, but does not alter the signal 
intensity or contrast of the MPF images. Therefore, the registered MPF 
images still reflect the macromolecular proton fraction of the brain 
tissue, which is independent of the T1 values.


Just wanna confirm. This is from a colleague.

Hi,

Please I made an initial enquiry about using freesurfer
for MPF maps. The feedback was that I register the MPF
maps on their corresponding T1 images using multimodal
registration. I used FSL to do the multimodal registration
and then use recon-all in freesurfer.

Now I want to know what the intensity and the volume of
the output in the aseg file represent. Is it the intensity
of the MPF or the TI and MPF?

Re: [Freesurfer] Recon-all Longitudinal Talairach issue

Dear all,

I have run recon-all successfully on multiple subjects on multiple 
timepoints. If I open the mri folder, it shows the correct talairach 
files and no issues arose during processing.


However, when I then run the longitudinal pipeline (first base, which 
also shows correct files) on the subjects (recon-all -long SUBJXXtp1 
SUBJXXbase -all) the talairach shows an failure detection and the 
subsequent file is talairach.invalid.mgz.


The actual segmentation etc. seems fine when inspecting, but when I 
then want to run segmentBS.sh on these processed folders, it gives an 
error.


I have run this a few month back without issue, and had just a few 
subjects left, but now all of them show this same error. Any idea how 
this could be caused?

Re: [Freesurfer] MRIread and RAS orientation

The vol structure will reflect how the volume is stored on disk. If you 
have two files that have the same structure (ie, order of rows, cols,

header orientation.

MRIread. The resulting .vol matrices for both files were, however, 
identical (i.e., voxel at location  in file1.vol had the exact 
same value as voxel in location  in file2.vol). Would you 
happen to know if the indexing of the vol structure is expected to 
come out the same with MRIread, regardless of the orientation?

I think you can verify it by checking several [c, r, s] locations of

MATLAB. And the index starts from 1.

Hi Dr. Doug,

Thanks for your prompt reply!

I’m sorry it was not clear. Basically, I would like to extract the 
cortical volume for each subject using a pre-defined ROI. As I have 
already created the surface ROI, thanks to your answer on the official 
website, I have no further question now on ROI.


This group analysiscan’s further survive the multiple correction using 
the mri_glmfit-sim that you gave me years ago, so there is no file 
like cache.th40.neg.sig.ocn.annot as before.


Instead, I tried to create a ROI and run command line as $mri_segstats 
--seg mask1.sm1.bin.mgh --exlude 0 --i 
groupAnalysis/lh.volume.g2v2.10.mgh --avgwf lh.volume.mask1.dat, where 
mask1.sm1.bin.mgh is the ROI and groupAnalysis/lh.volume.g2v2.10.mgh 
is the mris_proc processed file from a group of subjects. It did 
extract something, 1 number for each subject, but I believe there is a 
ratio or scalar between the actual volume of that vertex and those 
show in lh.volume.g2v2.10.mgh. Is there anywhere I can figure out 
where this ratio/scalar is? Thank you so much!

Do you need help with this? If so, can you give more info?

I have a further question as using this ROI to extract surface
information from ?h.area and ?h.volume. I’m using the command line

$mri_segstats --seg mask1.sm1.bin.mgh --exlude 0 --i
groupAnalysis/lh.volume.g2v2.10.mgh --sumwf lh.volume.mask1.dat

However, due to the calculation of surface and volume, we need
another input of sum file (ASCII file), how can I do that before I
can run the above?

Sorry, I don't know what you mean

Another simple question is, what is lh.volume.mgh in the group
analysis folder processed by mris_proc? Is that a simple merge of
all subjects lh.volume file? Why the number is between 0-10, is
there any way I can put ?h.volume or ?h.area back to gain each
subject’s real volume or area value on that surface vertex? Thank
you so much!

This is a vertex-wise measure of volume of the cortex at that point. 
Eg, a given vertex has an area defined by the mean area of the 
triangles that abut it. When this  is multiplied by the thickness, you 
get a volume measure (we actually compute it differently using a 
truncated pyramid, but that's the basic idea). You can use this in a 
VBM-like analysis.

*Subject:* Create a Binarized ROI for Surface

Dear Freesurfer Expert,

We would like to extract mean Cth values for each subject within a
own-creaded ROI (surface defined), using freeview (for instance).
Is it possible to create a ROI (i.e. spherical surface)
surrounding a particular vertex of an sig.mgh file? (and then
extract its mean Cth values for each subject)?

I think this is not a new question, and it was posted somehow on

Re: [Freesurfer] make_average_subject command error

[Huang, Yujing]

If you run recon-all, ?h.pial will appear as symbolic links to ?h.pial.T1.  
Here is the list of symbolic links you should find in your subject/surf 
directory:

rh.pial -> rh.pial.T1
lh.pial -> lh.pial.T1
rh.fsaverage.sphere.reg -> rh.sphere.reg
lh.fsaverage.sphere.reg -> lh.sphere.reg
rh.white.K -> rh.white.preaparc.K
rh.white.H -> rh.white.preaparc.H
lh.white.K -> lh.white.preaparc.K
lh.white.H -> lh.white.preaparc.H

I'm wondering why the symbolic links are not created.

To create the symbolic links,
1. cd to subject/surf directory
2. run ln command to create each link, for example, 'ln -s lh.pial.T1 lh.pial'

Best,

Yujing

Subject: [Freesurfer] make_average_subject command error


External Email - Use Caution

Dear Freesurfer experts,



We're trying to make an average subject for group analysis using Freesurfer 
7.1, but the make_average_subject command exits with errors after calling 
make_average_surf:


MakeAverageSurf(): 129 lh pial sphere.reg talairach.xfm 1 1


It appears to be trying to find the lh.pial surface for the first participant, 
but this file is named "lh.pial.T1". (In FS 5.3 and 6.0, this file was labelled 
"lh.pial", but with FS7.1, it seems to be named lh.pial.T1).


Does anyone have a suggestion for how to fix this problem? (We want to avoid 
changing all the file names to "lh.pial" from "il.pial.T1")
Should we call make_average_subject again with -no-surf-to-surf ?

Best regards,
Asuka

[Freesurfer] Calculation of MRI intensity

[ERNEST KISSI]

External Email - Use Caution

Hi Freesurfer Team,

Please I want to calculate the mean intensity of a skullstripped MRI image.
I do not want to use recon-all because I do not want to parcellate or
segment it. Is there such utility or function in freesurfer?

Thank you.

Sincerely,
Ernest Kissi Kontor.

Dear Yujing,

Thank you for your kind help (and sorry for my late reply).
It worked with the added flag; - measures thickness.
I appreciate your advice on adding directives at the end of the recon-all 
command.

Dear Yujing,



Thank you very much for your kind help.



So, you're saying I need more directive other than -qcashe?

My command was;

for d in Te* te* EPK* epk*

do recon-all -s $d -qcache

done



Do you think I should add another directive, such as -all or -autorecon-all?

So, the command line looks like this?

recon-all -s -subjid -qcashe - autorecon-all



I ran recon-all -qcashe not on the fsaverage folder, but in the SUBJECT_DIR.

In the previous post, I attached the wrong recon-all log (which was from 
fsaverage>scripts folder), but now I'm attaching the recon-all log file from a 
random subject folder.

Could you please look and check this recon-all as well?

Many thanks!



Best,

Asuka

Your recon-all command doesn’t have the directive to tell it what to run. You 
also need to specify input files for your initial run.  See this wiki page for 
detail MailScanner has detected a possible fraud attempt from 
"secure-web.cisco.com" claiming to be

The recon-all.log attached contains runs between 2009 and 2010 on subject 
‘fsaverage’.



‘fsaverage’ is an average subject comes with Freesurfer distribution in 
$FREESURFER_HOME/subjects/. fsaverage is a template brain based on a 
combination of 40 MRI scans of real brains. It can be used as a common space 
for group comparison. You don’t want to run recon-all on it.



Your SUBJECTS_DIR should not set to your Freesurfer download/install directory. 
Set it to some other directory where you have the write permission.



You should see ‘fsaverage’ as a symbolic link in your SUBJECTS_DIR.

Dear Freesurfer researchers,



I have an issue with recon-all-qcashe results. (please find the recon-all.log 
attached.)

The command created fsaverage mgh files (e.g., lh.thickness.fsaverage.mgh), but 
it did not create fsaverage files with different smoothing levels (e.g.,  
lh.thickness.fwhm10.fsaverage.mgh, lh.thickness.fwhm15.fsaverage.mgh, 
lh.thickness.fwhm20.fsaverage.mgh...etc) in the individual subject "surf" 
folder.



I used the command below:

for d in Te* te* EPK* epk*

do recon-all -s $d -qcache

done



(Subjects names start from either Te, te, EPK or epk)

For several subjects with failed recon-all commands, I re-ran the command 
individually:

 recon-all -s subjectname -qcashe



(output from the terminal window)

It could also be that recon-all was running at one point but died in an 
unexpected way.

If it is the case that there is a process running, you can kill it and start 
over or

Hello freesurfer experts ,
I change the command and reduce the threads from 200 to 50 , seems ok now ,
I use the cluster to run the jobs and submit jobs to cluster, I found there
have several jobs assigned to the same node , do this be ok to run
different subjects in one node with the same time ? Thanks.

[Freesurfer] make_average_subject command error

[Asuka Toyofuku]

External Email - Use Caution

Dear Freesurfer experts,


We're trying to make an average subject for group analysis using Freesurfer 
7.1, but the make_average_subject command exits with errors after calling 
make_average_surf:


MakeAverageSurf(): 129 lh pial sphere.reg talairach.xfm 1 1


It appears to be trying to find the lh.pial surface for the first participant, 
but this file is named "lh.pial.T1". (In FS 5.3 and 6.0, this file was labelled 
"lh.pial", but with FS7.1, it seems to be named lh.pial.T1).


Does anyone have a suggestion for how to fix this problem? (We want to avoid 
changing all the file names to "lh.pial" from "il.pial.T1")
Should we call make_average_subject again with -no-surf-to-surf ?

Best regards,
Asuka
