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? Second question. Is the format of the of the output (.mgh) correct?
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? 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.

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? An average subject is always in mni305
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). 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=s... libpng12-0_1.2.54-1ubuntu1_amd64.deb https://drive.google.com/file/d/1OWQSWL8a3Y8f1Weiauj9Lr2d3mtvZOm5/view?usp=s...
We also have an Ubuntu VM you can download. 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).

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!

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:

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

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,

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

External Email - Use Caution 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.

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. Andrew
