NeuroStars - a modern platform for providing user support
by Chris Gorgolewski 02 Jul '18

02 Jul '18

External Email - Use Caution Dear experts, I would like to introduce you to a (relatively) new platform (supported by INCF) for providing user support and letting users exchange and discuss ideas - http://NeuroStars.org. I know what you think - yet another website? what's wrong with email? NeuroStars has some nice features that makes everyone's life easier. For example: - When you start typing a question it automatically searchers all existing ones looking for similarities. Users can easily find answers without having to ask questions and the same question does not need to be asked twice: [image: Screenshot_9.png] - It's well indexed by google making it even easier for users to find answers [image: Screenshot_10.png] - It's not just for one project. Currently many projects (nipype, nilearn, mindboggle, fmriprep, mriqc, dhcp etc.) use it for user support. Each question has tags corresponding to its projects allowing for questions spanning multiple domains. You can choose which tags you will receive notifications about [image: Screenshot_11.png] All projects, experts and users are welcome at NeuroStars.org. All contributors are striving to provide friendly atmosphere and polite discussions. NeuroStars has potential to be the place where SPM, FSL, FreeSurfer, and AFNI come together! Best, Chris

Volumetric Group Analysis
by Mr. Tass 02 Jul '18

02 Jul '18

External Email - Use Caution Good morning I hope everyone had a gr8 weekend. im new here so i hope someone can help me understand a little about the right way to use freesurfer in order to calculate the gray matter volume for different areas of the brain and compare the volume between left and right hemisphere. so far i have freesurfer installed and recon-all a couple of test subjects. and everything seems to be working fine. i have several subjects with the axial cut MRI. is the axial cut enough to output accurate results? im little concerned as the T1 representation Outputted in FREEVIEW seems a bit fuzzy im following the below link for my group analysis. https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/VolumetricGroupAnalysis please if possible to sheld some light on this kind of analysis and if i am on the right track. thanks alot to you all best regards Sarah Get Outlook for Android<https://aka.ms/ghei36>

Poor anterior temporal lobe surfaces
by Meaghan Perdue 02 Jul '18

02 Jul '18

External Email - Use Caution Hello Freesurfer experts, I have tried several times to send this out, but I haven't received a response. Please let me know if there is a way to solve this issue. I have come across a problem with several subjects in which the pial surface fails to adequately capture the anterior temporal lobes. This occurs despite accurate brainmask and wm volumes. I have included a screen shot below, in this case, the wm surface is also affected, but this is not always the case. This is pediatric data that was acquired on a 1.5T scanner and processed in Freesurfer v 5.3. The following expert options have been employed to try to improve surface rendering: mris_make_surfaces -max_gray_at_csf_border 80 -max_csf 30 -min_gray_at_csf_border 35 Please let me know how I can solve this issue. As a second question, I've heard that segmentation and surface rendering is improved with v 6.0, and I'm wondering if subjects that have been initially run through v. 5.3 and had manual edits made can then have autorecon run through v 6.0 for improvement of surfaces? Please let me know if this would be a reliable/recommended approach to improving surfaces. Thank you, Meaghan Perdue -- Meaghan Perdue PhD Student Developmental Psychology Neurobiology of Language University of Connecticut Bousfield A302

Compute cortical thickness within VOI
by Alshikho, Mohamad J. 02 Jul '18

02 Jul '18

Dear FreeSurfer experts, I have MRS volume of interest (VOI) was placed in the motor cortex during MRS data acquisition. In order to compute the gray and white matter volume within the VOI, I synthesized this VOI using "mri_volsynth". Then I registered it to T1 Freesurfer space using "spmregister". Finally, I used "mri_segstats" to compute the gray and white matter volume for all the structures within this VOI. My question is how can I compute cortical thickness for the cortical structures within this VOI. By looking into "recon-all.log" I found that the command "mris_anatomical_stats" was used to compute cortical thickness from the surfaces. Is it a correct procedure to map this VOI onto surface using "mri_vol2surf" then feed the output into "mris_anatomical_stats" as an annotation file? Thank you for any guidance. Mohamad

degrees of freedom

External Email - Use Caution In group analysis, is it better to have matched controls (1:1) or to use age, education and other characteristics as confounds in the glm? In the latter situation, we would control for these demographic variables in the glm and the control group n could be smaller, the same or larger than the test group. We are looking at TBI+ and TBI- subjects across a broad age range to look at patterns of cortical thinning. Thanks. John R.

Proposed addition for Freesurfer - automated control points
by Chris Adamson 30 Jun '18

30 Jun '18

External Email - Use Caution Freesurfer devs, I presented an automated control point adding tool at HBM and a few freesurfer lab people came over and had a look. I was wondering if someone would like to review it for either inclusion or to perhaps reference from the wiki as a tool for people to use if they choose? Thanks in advance, Chris.

TIV should be considered as a covariant for thickness, volume and area analyses
by Ting Li 29 Jun '18

29 Jun '18

External Email - Use Caution Hi FreeSurfer Experts, I would like to do the surface analysis among two groups, like the thickness, volume and area. When I run the GLM, do I have to consider the eTIV as a covariant or not? Thanks a lot! Best wishes, Ting

mri_glmfit question
by Nillo, Ryan Michael R 29 Jun '18

29 Jun '18

External Email - Use Caution Hello FreeSurfer Users, I want to run an ROI-based analysis on mri_glmfit as opposed to vertex-based. I know that if I run mri_glmfit with the --table flag and give it the output of asegstats2table or aparcstats2table, it will run the analysis on the ROIs and output tables showing significance. In each contrast directory that was created from mri_glmfit, I see there is a pcc.mgh. Is there any way to display this on the surface or put it into a table format?
