Dear Freesurfer experts,

We are conducting a PETSurfer analysis, and have some questions on the best way to proceed.  Briefly, this is what we have done:

After running the standard Freesurfer analysis an all the T1 images, we have generated the segmentation for the GTM.
Afterwards, we have registered the PET images with the anatomicals, obtaining the template.reg.lta.
To check the preliminary results without any PVC, we have used the template.reg.lta to sample the PET volume onto the surface, with the following command:
 mri_vol2surf --mov subject_PET.nii \
 --reg subject_template.reg.lta \
 --projfrac 0.5 --interp nearest \
 --hemi lh --o lh.sig.mgh

We therefore obtained the lh.sig.mgh

First question. Is this procedure correct?
Yes (though you should always check the reg.lta with tkregisterfv). Also, why are you calling the output lh.sig.mgh? My question is about "sig"; it is not wrong to call it this, but "sig" is usually reserved for significance files and I wanted to make sure you were not confused by it.
Second question. Is the format of the of the output (.mgh) correct?
Any format (mgh, mgz, nifti) is ok.

In the wiki it is reported that: “If you are not using PVC, you can use the template.reg.lta to sample the PET volume onto the surface using mri_vol2surf, then apply standard surface-based analysis”.

Third question. At this point should we directly run the mri_glmfit with the previously obtained lh.sig.mgh?
This is probably not right. You  will need to run the mri_vol2surf command above for each subject to generate an output (and using --trgsubject fsaverage to put them into the same space), then concatenate all into one file (mri_concat lh.subj1.mgh lh.subj2.mgh ... --o lh.all.mgh), then possibly smooth (mris_fwhm), then feed that output as input to mri_glmfit.
Like in this way:

 mri_glmfit \
 --y lh.sig.mgh \
 --fsgd fsgd file dods\
 --C cor.mtx file \
--surf fsaverage lh \  
--cortex \
--glmdir glmdir

Many thanks for any information you’ll be able to provide,

 Best,

Pilar Maria Ferraro

Dear Freesurfer experts,

I hope you can help me with the following questions:

1. What is the best way to know the MNI coordinates to which a vertex of a
surface corresponds?

2. I have projected the surfaces of the subjects onto the average subject
from this dataset.
Can I know the MNI coordinates corresponding to a vertex of the average
subject of my dataset?
Or do I need to project it onto the fsaverage to know the correspondence to
de MNI space?

3. I know that the average surface is constructed by computing the MNI305
coordinate at each vertex,
But how can I obtain the MNI152 coordinates (instead of MNI305) to which a
vertex corresponds? (if it is possible).


Thank you very much in advance.

Best regards,
Marina

I think freeview will display the mni305 coords

2. I have projected the surfaces of the subjects onto the average
subject from this dataset.
Can I know the MNI coordinates corresponding to a vertex of the

Or do I need to project it onto the fsaverage to know the

An average subject is always in mni305

3. I know that the average surface is constructed by computing the

But how can I obtain the MNI152 coordinates (instead of MNI305) to

See case 8 in website above

Hello Stephan,
There is some information here about packages to install in order to run freesurfer - see highlighted "apt-get install" commands.
https://surfer.nmr.mgh.harvard.edu/fswiki/BuildRequirements
I think you will also need to install these packages,
libjpeg62_6b2-3_amd64.deb
https://drive.google.com/file/d/1Zdd-C3EQEEww180OzxEk1WV0h9obZYkD/view?usp=sharing
libpng12-0_1.2.54-1ubuntu1_amd64.deb
https://drive.google.com/file/d/1OWQSWL8a3Y8f1Weiauj9Lr2d3mtvZOm5/view?usp=sharing

We also have an Ubuntu VM you can download. &nbsp;While you may prefer to run on your own Ubuntu machine, it could also serve as a reference for you to see what we installed on Ubuntu 18.04 (including those extra packages).

Hi FreeSurfer Experts,

As recommended I ran the following command:

mri_glmfit-sim --glmdir rh.volume.AgeSex.10.glmdir --perm 1000 3.0 abs --perm-resid --cwp 0.05 --2spaces

And I got the following error message:


ERROR: Flag --perm-resid unrecognized.

Hi Freesurfer community,

I have an issue that I spent ages trying to figure out and this error has
been asked about back in (17/12/2016) and the title is ([Freesurfer]
Tracula trac -all preprocessing error.

my error is:

ERROR: fio_pushd: /Volumes/HD/Post_HARDI/PAH_Clinical_110/07/C07/dlabel/mni

There is an issue that the mini folder is empty.

Attached is the log file and the configuration file (tracula_conf.txt)

Hi Freesurfer Community,

I have run Hippocampus subfield segmentation using scans from GE and
Siemens. The field of view (FOV) for GE and Siemens are different, with FOV
of 8 and 9 respectively. Will this affect the analysis since they have
different FOV?

Thanks,

Kate

Dear Freesurfer experts,

I have a little question about the structure 'chorid-plexus', I am not very
deep in brain anatomy and function. Could anyone have a sense of what is
the normal range of this structure volume from Freesurfer reconall?

I found that mean of 'chorid-plexus' in ADNI is around 1500 mm^3, when I
ran reconall for my local subejcts (a local dataset), I found the mean of
'chorid-plexus' is around 800 mm^3.

Could anyone give an explanation or a paper I could refer to for this
'chorid-plexus' structure?

Thanks  so much!

Best Regards,
An Lijun

Hi An Lijun

The choroid is a plexus of ependymal cells that produce CSF. it is pretty
tough to segment and mostly we include it to get more accurate segmenations
of the hippocampus where it is adjacent to ventricle and the ventricles
themselves. I'm not sure I've ever seen any normative stats on it though.

You can read more here:

????????External Email - Use Caution????????

Dear Freesurfer experts,?

I have a little question about the structure 'chorid-plexus', I am not very deep in brain
anatomy and function. Could anyone have a sense of what is the normal range of this
structure volume from Freesurfer reconall?

I found that mean of 'chorid-plexus' in ADNI is around 1500 mm^3, when I ran reconall for my
local subejcts (a local dataset), I found the mean of 'chorid-plexus' is around 800 mm^3.

Could anyone give an explanation or a paper I could refer to for this 'chorid-plexus'
structure?

Thanks? so much!? ?

Best Regards,An Lijun

Hello   Freesurfer team

I checked the freesurfer version 7.0.  It says that "  but for now you
should know that some features are not present in v7 (QDEC, GPU-capability,
and recon-all -make)."

https://surfer.nmr.mgh.harvard.edu/fswiki/dev7beta1

But from the hardware setup, it still needs  Graphics card: 3D graphics
card with its own graphics memory & accelerated OpenGL drivers.

This makes me confused.    Since version 7 does not support GPU anymore,
why does it still need the Graphic card?  I found GPU may be helpful for
some abnormal brain such as large ventricles. It may speed the calculation
time.   I do not know my observation is correct or not.

Thanks

Frank

It should be fine but please make sure you correct by scanner in subsequent analyses.

Hi Freesurfer Community,

I have run Hippocampus subfield segmentation using scans from GE and Siemens. The field of view (FOV) for GE and Siemens are different, with FOV of 8 and 9 respectively. Will this affect the analysis since they have different FOV?

Thanks,

Kate

Hi Frank,

We still recommend this since freeview benefits from having a fast GPU.

Hello   Dr.  Hoopes

Does it mean that in Beta version 7,  there is no GPU capability.  But
stable version 7 still support the existing GPU capacity..   Is it correct?

It means CUDA-accelerated binaries/recons on the GPU are no longer supported after freesurfer 6.0. I will make that clarification in the wiki page. Sorry for the confusion.
