FSGD file formatting for Xhemi
by Jose Graterol 11 Nov '19

11 Nov '19

External Email - Use Caution Dear Freesurfer Community, I have a question regarding the formatting of the FSGD file while doing an analysis with Xhemi. First the --y file was created as previously explained in another discussion ( https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg63965.html) That is, mris_preproc with --xhemi and no --fsgd flag. If I understood correctly, that would create a mgh file with the following order: sub01lh, sub01rh, sub02lh, sub02rh... Then the FSGD file while running mri_glmfit would be: GroupDescriptorFile 1 Title xxx Class sub Variables var1 Input sub01lh sub var1_lh_sub01 Input sub01rh sub var1_rh_sub01 Input sub02lh sub var1_lh_sub02 Input sub02rh sub var1_rh_sub02 Would this be correct? If so, what would be the best case for specifying a variable like age? Just repeating the value 2 times? As always, thanks in advance Kind Regards José

how to compute geodesic distance and intensity
by chenyang jiang 11 Nov '19

11 Nov '19

External Email - Use Caution Dear fs developer Hello, I want to compute Geodesic distance and intensity contrast in all the vertices based on T1 image, and also could get the feature map to do the statistical analysis. Is there any code or toolbox could handle with it. It will be better if the input is from freesurfer output. thanks so much, chenyang

low snr with t1_mp2rage compared to MPRAGE
by Knut J Bjuland 11 Nov '19

11 Nov '19

External Email - Use Caution Dear freesurfer experts, I have some image that are in t1_mp2rage_sag. Are there anything I should be aware of when importing them into freesurfer from nifit? How can I detect what sequence that is used in the MRI dicoms? When I compare these images with MPRAGE dicom I get lower snr measured with wm-anat-snr with, what can cause this? Best regards Knut Jørgen Bjuland

Inconsistent Morphology Output
by Chen, Christine 11 Nov '19

11 Nov '19

External Email - Use Caution Hello, My lab has been running T1 (MPRAGE) data through run_subject (uses recon-all, autorecon, mris_volume and mris_wm_volume) then through run.r (pulls freesurfer.r and pedbirn.r) using the Desikan-Killiany atlas to output measures of cortical morphology. We've always gotten consistent output when rerunning data, however, lately when rerunning data using the exact same files as before, the output measures are different, sometimes significantly so, compared to when they were previously run. We recently installed the development version of FreeSurfer in a path different from $FREESURFER_HOME, which is still set to usr/local/freesurfer. We've also confirmed that all these runs have been using FreeSurfer v6.0 by looking at the /scripts/build-stamp.txt file. So the inconsistency in output might not be due to the FreeSurfer version used. Additionally, we are collecting a new dicom format, however when rerunning files collected in the previous dicom format through the pipeline and comparing this output to the output from when it was previously ran, the measures are still different, so the inconsistency in results might not be due to the dicom format. Do you have any ideas why this sudden change in outputs is being observed? Is there a flag we can add to the scripts to ensure results are identical and consistent with what they were previously, such as -norandomness or -seed 1234? Any help or guidance would be greatly appreciated. Thank you in advance.

External Email - Use Caution Dear Freesurfer experts, I run the command mri_glmfit --table aseg.volume.stats.dat --fsgd GLM7.fsgd dods --C contrasts6.mtx --glmdir NFL.aseg.glmdir This gave me the output sig.table.dat. Is there a way to implement an FDR to this analysis in Freesurfer or do I have to use another statistical program for that? Many thanks for your support! Best regards, Ben

Question about convert fsaverage to fsaverage5
by chenyang jiang 11 Nov '19

11 Nov '19

External Email - Use Caution Dear Fs Developers Hi, I am new to freesurfer, after I ran the recon-all command, I want to align the individual surface to fsaverage5 space. and then extracted the cortical thickness of each vertex. Should I use mri_surf2surf to do it, What's the specific parameter I should set up? like srcsurfval , trgsurfval and so on. would it be possible to give me entire command setting. Thank you so much!

T2 white matter surface refinement
by Defenderfer, Matthew K 11 Nov '19

External Email - Use Caution Hi, Looking through the documentation, there are extra options to include a T2 image to refine the pial surface boundary, but I was wondering if FreeSurfer can use a T2 in conjunction with a T1 to help refine the white matter/gray matter boundary? As in, gray matter with higher myelin content than average could cause the white matter boundary to be placed further out than normal when just using a T1; can FreeSurfer currently use a T2 image to help prevent that at all? Thank you -Matt Matthew K.

Longitudinal Analysis for functional connectivity data?
by Barbour, Tracy,M.D. 11 Nov '19

Hello Freesurfer experts! I see that there is a longitudinal processing pipeline for volume/cortical thickness. I was wondering if the same pipleline could be used for resting state functional connectivity based analysis? Best, Tracy

mri_surfcluster error -- FsFastTutorialV6.0
by 王如雪 11 Nov '19

11 Nov '19

External Email - Use Caution Hi Sir/Madam: I got an error when executing the new version "mri_glmfit-sim" correction for multiple comparisons with permutation at the group level according to FsFastTutorialV6.0. This was the command I used: "mri_glmfit-sim --glmdir my-glm --perm 1000 1.3 pos --cwp .05 --2spaces" But it prompted: mri_surfcluster: could not read surface /home/freesurfer/subjects/fsaverage4/surf/lh.white No such file or directory after "mri_glmfit simulation done" However, I've verified that /home/freesurfer/subjects/fsaverage4/surf/lh.white existed and that I had read permission to it. And after I loaded it with freeview -f /home/freesurfer/subjects/fsaverage4/surf/lh.white, the lh.white file was opened in the freeview window while the command line prompted "Did not find any volume geometry information in the surface". Can you help me with this error? Thank you very much! Best, ---------------- Ruxue Wang PhD Student, Tsinghua University
