Extracting individual activation values in FSFAST
by Fang, Angela,Ph.D. 08 Mar '21

08 Mar '21

Hello Freesurfer community, I would like to extract individual brain activation values in specific clusters emerging from an FSFAST group analysis that tested a certain contrast during a task, to be entered as predictors in a linear regression model. Is it possible to obtain these individual level activation values using commands in FSFAST? Or is it possible to extract individual level effect sizes from this group analysis from the contrast effect size files? Thanks so much for your help!

Unknown label interpretation in Desikan-Killiany atlas
by Yu-Wei Chang 08 Mar '21

08 Mar '21

External Email - Use Caution Dear FreeSurfer Support, I am writing this letter to inquire about the labeling system for Desikan/Killiany atlas. Specifically, we would like to ask whether the label "CTX_LH_UNKNOWN_SUVR" shall be included for the anaylsis or not. -- As far as we are concerned, we found the related information in archives of FreeSurfer support: https://secure-web.cisco.com/1pj3f15nIYncSqPaxZxKxOkPY68taDPj-zLxvjs3pwd01d… unknown volume means it's not part of the cortex (usually on the medial wall where the surface crosses things like the callosum, the thalamus, the ventricles, etc...) -- It appears that the value of this label is meaningful in our current analysis. Therefore we would very much appreciate if you can give us some suggestions or elaboration about the unknown label in freesurfer, and how to interpret it. Sincerely, Yu-Wei **************************** Yu-Wei Chang 張育瑋 Doctoral student UNIVERSITY OF GOTHENBURG Department of Physics Gothenburg, Sweden

Clusterwise Correction for Multiple Comparisons
by Weerasekera, Akila 08 Mar '21

08 Mar '21

Hi, After running mri_glmfit-sim (two classes) and freeview -f $SUBJECTS_DIR/fsaverage/surf/rh.inflated:overlay=cache.th13.pos.sig.cluster.mgh I get this: I would like to know if this due to an error (do I need to change threshold) or no significant clusters. [cid:fdfe3765-85b2-46f6-a3b5-40fa35eb78cd] Thank you, best Akia Akila Weerasekera, PhD | Postdoctoral Research Fellow Maria Mody lab for Developmental Language and Reading Research Laboratory | Eva Ratai Lab for Clinical Spectroscopy | Garry Nolan Lab (Stanford University) | Harvard Medical School | A.

Issues with mris_preprocess and fsaverage5
by Amanda Rodrigue 08 Mar '21

08 Mar '21

External Email - Use Caution Hello, I am attempting to run mris_preproc with a single subject using the following command: mris_preproc --s 6026423 --fwhm 10 --SUBJECTS_DIR /lab-share/Psych-Glahn-e2/Public/UKB_4844/FS_MRI --target fsaverage5 --hemi lh --meas thickness --out /lab-share/Psych-Glahn-e2/Public/UKB_4844/FS_analysis/PRS_reg/THICK/${s}.fs5.10mm.lh.thick.mgh Although I have copied the fsaverage5 directory to my SUBJECTS_DIR, I am getting the following error: mri_surf2surf: could not read surface /lab-share/Psych-Glahn-e2/Public/UKB_4844/FS_MRI/6026423/surf/lh.fsaverage5.sphere.reg No such file or directory What's strange is that I tried the same command, but instead of using the fsaverage5, I used the fsaverage (which is also located in my SUBJECTS_DIR) and it works fine. I've attached both the log files when using the fsaverage and when using the fsaverag5. Am I missing something obvious? Any input is appreciated, Amanda -- Amanda Rodrigue, PhD Boston Children's Hospital Harvard Medical School 1 Autumn St. Boston, MA 02215

mris_sphere error: terminated by signal 9
by Gool, Raquel van (Stud. FPN / Alumni FPN) 08 Mar '21

08 Mar '21

External Email - Use Caution Dear FreeSurfer experts, I'm attempting to use recon-all on my subjects and I have one of my subjects exit with errors after it is terminated by signal 9 during -sphere of autorecon3. I tried rerunning this particular step with command recon-all -autorecon3 -subjid subj07 -sphere. Unfortunately mris_sphere keeps being terminated. I experience this exact same problem with another one of my other subjects, whereas the rest of my subjects manage to finish recon-all. I use freesurfer-linux-centos7_x86_64-7.1.0-20200511-813297b on a virtual machine (VirtualBox) on my windows computer. Linux developer-VirtualBox 5.4.0-65-generic #73~18.04.1-Ubuntu SMP Tue Jan 19 09:02:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Any thoughts on how to troubleshoot this? Thanks a lot. Regards,?

Freesurfer consult
by 周诚 06 Mar '21

06 Mar '21

External Email - Use Caution Dear Sir, Sorry for the inconvenience, We meet a trouble when using the Freesurfer. We desire to resampling structural data in the diffusion space. But the diffusion data were processed using FSL. There is no register.dat, but according to Freesurfer' tutorial, you must have a register.dat to conduct mri_vol2vol or other functions. Could you tell me how to deal with this trouble? Hope to your reply and thank you very much. Sincerely, Cheng Zhou Zhejiang University
