eTIV vs. manual ICV
by Alexopoulos, Dimitrios 17 Apr '20

17 Apr '20

External Email - Use Caution I was just wondering if using the eTIV from FS 6.0 is a reliabile measure for intracanial volume normalization. Typically, manual ICV includes extra-axial CSF which I don't think is included in the eTIV method, correct? Our population is a control adoloscent cohort and we are interested in global GM and WM, and cortical aparc volumes.

Re: [Freesurfer] Does FS guarantee the same results if run several times?
by Xiaojiang Yang 17 Apr '20

External Email - Use Caution Thank you Douglas! In my case, two runnings were from Centos7 and Redhat7 respectively. Good thing is that the difference of the average thickness is small - it's 0.006 mm. Both lh and rh have 0.006 mm differences, but one's lh is thicker than the other's, while its rh is thinner than the other's. Xiaojiang

Re: [Freesurfer] Does FS guarantee the same results if run several times?
by Xiaojiang Yang 17 Apr '20

17 Apr '20

External Email - Use Caution Hi Douglas, I checked the recon-all.log files for both, and found the difference - my mistake, one used FLAIR as extra input and the other did not. I did find another case that has two different results in two runnings. Both runnings have MPRAGE and FLAIR as inputs, but one of the runnings has used the option "-openmp 16", and the other did not. Also, the two runnings were from two different machines. What do you think is the factor that has caused the different results, the openmp or different machine? The FS on two machines are the same version (V6). Thanks! Xiaojiang

Hi all, Which of the three autorecons makes use of https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfields flags? autorecon1, 2 , or 3? My goal is to use the flag specifically with one of the three and not with recon-all in general as shown in the above page.

Re: [Freesurfer] PET Surfer / New questions
by Ferraro, Pilar 17 Apr '20

17 Apr '20

External Email - Use Caution Dear Freesurfer experts, Many thanks for your prompt reply and all the helpful information. Below are few remaining questions I have (in red), based on your responses. Many thanks again, Pilar 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. Yep yep, sorry I’ve forgotten to specify we also checked the reg.lta for each subject with tkregisterfv. As regards the name of the output you are totally right, we just called it in this way cause we found an example of the mri_vol2surf command application which used this name for the output, but yeah, without any significance it would be more appropriate to call the output in a different way to avoid any confusion. Second question. Is the format of the of the output (.mgh) correct? Any format (mgh, mgz, nifti) is ok. Perfect, thanks, but it is unclear to me which would be the best way to visualize this output (and this aspect might influence the type of format we would choose). Do you have any suggestions? 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. Sounds good, I’ll proceed in this way. Only one remaining question. Is it really ok to smooth even if it creates PV effects? Many thanks as always for the precious help, Pilar 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 Il giorno 15 apr 2020, alle ore 5:18 PM, freesurfer-request(a)nmr.mgh.harvard.edu<mailto:freesurfer-request@nmr.mgh.harvard.edu> ha scritto: Send Freesurfer mailing list submissions to freesurfer(a)nmr.mgh.harvard.edu<mailto:freesurfer@nmr.mgh.harvard.edu> To subscribe or unsubscribe via the World Wide Web, visit https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer or, via email, send a message with subject or body 'help' to freesurfer-request(a)nmr.mgh.harvard.edu You can reach the person managing the list at freesurfer-owner(a)nmr.mgh.harvard.edu When replying, please edit your Subject line so it is more specific than "Re: Contents of Freesurfer digest..."

If so, there will be a slight decrease from the standard resolution because the underlying rendering library that we use unfortunately does not support retina capabilities at this time. Also, are you loading single or multiple volumes? Freeview uses the first volume loaded as the base image geometry, and all the following volumes are resampled (if necessary) into this base geometry using nearest neighbor interpolation. So if you?re working with different-resolution images, it might help to enable linear interpolation as the default resampling method by using the `--trilinear` freeview flag.

Inaugural message to the list; I will attempt to be brief with the project description. The setup is consistent between both versions 6.0.0 and 7.0.0-beta, run on a high performance cluster, accessed through macOS terminal + Xquartz, most recent versions all. As it stands, our group is attempting to do subfield analysis of hippocampal analysis and lesion measurement in MS subjects. We have noticed that there is a major discrepancy of resolutions between files, which has irked some of our physicians undertaking the lesion measurement. We need to resolve the lesions down to 3mm and have noticed the quality between freeview and fsleyes of the same nifti files will yield much lower display resolution. This is true for most scans, though it has been compared using 1mm T2 FLAIR sequences as well as T2* sequences with 0.65mm voxel space. I have been attempting to find a workaround as the current solution for the physicians is to look at the files in fsleyes and then measure them with the ruler tool in freeview.

My questions are: 1) In general, should I prefer FLAIR over T2, or the other way around? 2) Some subjects (< 10%) do not have a FLAIR image, and others do not have a T2. Do you think that it is fine to use FLAIR for some subjects, and T2 for others, in the same study? We will perform manual QC after the recon-all run and exclude bad quality images, so I feel it should be fine, but I wanted to hear your opinion.

I am trying to use an analysis package that works on surface based data (SamSrf). I have ran Feat and have a filtered_func file which is of course the motion corrected/unwarped version of my EPI. However, I need some advice on how to get these data onto the Freesurfer surface. I have found this page<https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FreeSurfer>, but I wanted to double check this is the most up-to-date pipeline. On the page it suggests using the same DOF as used in Feat, I use BBR so this seems a little redundant. Has anyone on these lists got any experience of getting filtered_func onto the Freesurfer surface?

I have a minor (may be a major) issue. when I generate label files for a tissue e.g midbrain by using the command mri_vol2label --c $SUBJECTS_DIR/bert/mri/brainstemSsLabels.v10.mgz --id 173 --l midbrain.label or in voxel space mri_vol2label --c $SUBJECTS_DIR/bert/mri/brainstemSsLabels.v10.FSvoxelSpace.mgz --id 173 --l midbrain1.label ?Now I want to lad the label file and the MRI volume, brainstemSsLabels.v10 , in Matlab (I can do this by using MRIread function given in FSmatlab directory. the function read mri in a matlab struct, which along with other info also contain a 'vol' 3D data matrix) ? Using the coordinates given in label file, how to extract a specific slice, row, column from a matlab matrix? as the label file need some transformation, I dont know this part. Any help shall be highly appreciated.

cw256 option not working?
by Soichi Hayashi 17 Apr '20

17 Apr '20

External Email - Use Caution Hello. I am trying to run recon-all on HCP7T data and seeing this error message. **************************************** ERROR! FOV=268.800 > 256 Include the flag -cw256 with recon-all! Inspect orig.mgz to ensure the head is fully visible. **************************************** I've looked at orig.mgz, and it looks fine to me (screenshot attached). Anyway, I've added the -cw256 option to the command line. $ recon-all -i ../5e977c0dfe00f4e4b4976207/5a052586eec2b300611abffc/t1.nii.gz -subject output -all -parallel -openmp 8 -hippocampal-subfields-T1 -hires -cw256 However, I am still seeing the same error message saying that I should add the flag -cw256. Am I setting this option incorrectly? I am using freesurfer version 6.0.0. Thank you! Soichi Hayashi [image: Screenshot from 2020-04-17 12-28-01.png]
