Tracula tracts do not display correctly and have large volume
by Goeckner, Bryna 29 Mar '22

29 Mar '22

External Email - Use Caution Hi Freesurfer Experts, I have run into a problem with several subjects ranging over several different tracts (usually just one tract per subject) where a tract will not display correctly in merged_avg16_syn_bbr.mgz or in the individual pathway (ex: lh.cbv_avg16_syn_bbr/path.pd.nii.gz) without first adjusting thresholds. I also discovered that the volume in pathstats.overall.txt in these cases is significantly higher than the average – on the order of 10 times bigger. I know there is mention of using “set reinit=1” to repair tracts that are too small or missing. Would this be recommended here as well or is there another better direction to take? I am including a link to the trac-all.log for a subject whose rh.ilf is problematic. Please let me know of there is any other information you need and thanks for your help! https://secure-web.cisco.com/1-H9YB7x0pcdABFBAqsjeogpPsh-50RChRNS5qTyoP0bcn… Bryna Goeckner (she/her) Graduate Student Medical College of Wisconsin Neuroscience Doctoral Program

External Email - Use Caution Hello KC, You should try getting a new license.txt via,https://secure-web.cisco.com/1F7uoRb2K1btXJW51ulbB_sBWkHIL6Y-0iC-V12bpS… to use on the new system instead of your existing license.txt.  How licenses are read on your new system may no longer works with your old freesurfer license.txt file. The libpng12.so error may be because that is not installed on your new system.  If you let us know what operating system your new system is running, e.g., CentOS8, Ubuntu 20, etc. then maybe we can help you with that. - R.

Re: [Freesurfer] GLM analysis - volume and surface area
by Laura Willers de Souza 29 Mar '22

29 Mar '22

External Email - Use Caution Of course! To do GLM for volume and surface area analysis, is there any change in commands in relation to cortical thickness analysis? Like some more command, or some other detail that must be changed (besides, of course, the flag that specifies the measure to be analyzed) - I'm already using permutation in the correction of multiple comparisons. Many thanks! ------------------------------------------------------------------------------ On 3/09/2022 15:20 PM, Douglas N.

Greve wrote: Yes, it is. It is confusing when you talk about area and volume since these are not point measures like thickness (ie, what is the volume or area of a vertex?). The area of a vertex is computed as the mean of the adjacent triangles of the vertex. The volume is the mean of the neighboring truncated tetrahedra. When you run mris_preproc, it will apply a jacobian correction (like VBM). Otherwise, it operates the same as if you had a thickness value at the vertex, ie, same GLM, etc. Make sure to use permutation for correction of multiple comparisons. ----------------------------------------------------------------------------------------- On 2/21/2022 12:13 PM, Laura Willers de Souza wrote: Hello FreeSurfer Developers, I would like to know if it is correct to perform volume and surface area analysis using freesurfer's GLM!? In several mailing list questions I have already seen instructions for performing these types of analysis. But I understand that freesurfer does vertex-wise analysis in the 2D surface space. So, it is not clear to me how it is possible to evaluate a 3D measurement, as volume, with a 2D method!? I've also read that surface area analysis via vertex-wise analysis doesn't make much sense. The best would be to do ROI-based analysis. Can you explain that to me? Thanks in advance!

[Moved to Europe Friendly Time Zone] DPABINet Brain Network Online Training Camp
by YAN Chao-Gan 29 Mar '22

29 Mar '22

External Email - Use Caution *[Given that most registered trainees are from Europe, the training time was moved to Europe friendly time zone]* The human brain is one of the most complex network systems in the universe, consisting of about 1011 neurons and about 1015 connections. Since the human brain is a highly integrated and cooperating complex system, studying the functional integration between different brain regions is crucial for understanding the information interaction between brain regions and the coordination between brain networks. In order to facilitate brain network research, Dr. Chao-Gan Yan’s team (The R-fMRI Lab <http://secure-web.cisco.com/14xnlK7Eei_sMSO3_q06ck_peQQ9l9mK7haGZZZlWLewMoB…>) developed a free and open source software DPABINet. DPABINet V1.1 has been released with DPABI <http://secure-web.cisco.com/1_qe887wfdc3X7xMhXFFxKI3dZeE4yMD6gK6oK8hJUqdJM0…> V6.1, which can construct brain network, calculate graph theory indices, perform statistical analyses and present brain network images. In addition, to better construct the brain network, we recommend using DPABISurf <http://secure-web.cisco.com/1SOajXUcJEucbuq3zxd8N5GctqwVz0Y0Xi5nyChupOjOeXQ…> for surface based preprocessing. DPABISurf is a surface-based resting-state fMRI data analysis toolbox evolved from DPABI/DPARSF, as easy-to-use as DPABI/DPARSF. DPABISurf is based on fMRIPrep, FreeSurfer, ANTs, FSL, AFNI, SPM, dcm2niix, PALM, GNU Parallel, Docker and DPABI. DPABISurf provides user-friendly graphical user interface (GUI) for pipeline surface-based preprocessing, statistical analyses and results viewing, while requiring no programming/scripting skills from the users. The use of DPABINet and DPABISurf is as simple as DPABI software, but hands-on practical training can make users proficient in DPABINet brain network analysis in the most correct and effective way. As there was no online English video course for DPABINet yet, here we are launching the DPABINet Brain Network online Training Camp (April 18th ~ 22nd, 2022, the teaching language is English). This DPABINet Brain Network online Training Camp <http://secure-web.cisco.com/1d8dz5C6fbHOk7tUc0T0Lt9q2Mf3Hh2_sNdSoujvhTLv5fN…> is lectured by Dr. Chao-Gan Yan, and is aimed at researchers and students in the fields of psychology, cognitive neuroscience, biomedical engineering, clinical medicine, etc. Because this training camp requires basic knowledge of brain imaging, we encourage the trainees first learn The R-fMRI Course <http://secure-web.cisco.com/1R8odPSiNAmJLVsOInsWj0xbQLHTWbYsgKlfqzm_YIL_bTh…> (freely available at http://secure-web.cisco.com/1R8odPSiNAmJLVsOInsWj0xbQLHTWbYsgKlfqzm_YIL_bTh…) In the training camp, trainees will first study DPABISurf for cortical reconstruction and data preprocessing, and then systematically learn brain network research, from the basic concepts of brain network to operations of DAPBINet software. More importantly, trainees are encouraged to come to study with their own projects and data, conduct in-depth research project discussions with the lecturer, process data with research questions, receive hands-on systematic scientific research training, get results and scientific interpretation for publication. We sincerely welcome your participation in this training camp and look forward to seeing you online! 1. Time: April 18th ~ 22nd, 2022 2. Language: English 3. Place: Online Camp This training camp is held in the form of cloud-based online small classes. Lectures and discussions will be held in the cloud conference Zoom room. One-on-one error-checking counseling by teaching assistants will also be held in the cloud small conference room. For trainees with insufficient local computing power, the cloud server will be opened for data processing exercises. 4. Lecturer Chao-Gan YAN, Ph.D. <http://secure-web.cisco.com/1igKvIBTP7egVAIAvbJj9df_8Qys2r-PtsZsZOksedvLKd2…> Dr. Chao-Gan Yan is a professor at the Institute of Psychology, Chinese Academy of Sciences (IPCAS). He is the Director of the Magnetic Resonance Imaging Research Center, the Director of International Big-Data Center for Depression Research, and the Principal Investigator of The R-fMRI Lab located at IPCAS. Before he joined the IPCAS in 2015, he worked as a Research Scientist at the Nathan Kline Institute for Psychiatric Research and a Research Assistant Professor at the Department of Child and Adolescent Psychiatry, New York University School of Medicine. Dr. Yan received his Ph.D. degree in Cognitive Neuroscience from State Key Laboratory of Cognitive Neuroscience and Learning at Beijing Normal University in 2011.

classes for GLM analysis
by Zeng, Victor (BIDMC - Keshavan - Psychiatry) 27 Mar '22

27 Mar '22

External Email - Use Caution Hi all, I am doing an analysis and generating the FSGD. I understand sex and race are classes in this context, but something I was also hoping to regress out is the effects of scanner/sequences. We have a large participant size, so we have around 10+ scanner/sequences, which makes for a large amount of classes combinations, with some having just 1 (if not zero) fitting into a class. Would you proceed with this nonetheless? If not, should scanner/sequence be something that we consider? Should we find some other way to adjust site (I don't think we can z-score...). Or can we consider site/scanner as a continuous variable Victor Zeng Beth Israel Deaconess Medical Center Keshavan Lab --
