Freesurfer vs. CAT12
by Maximo, Jose Omar 25 Sep '19

25 Sep '19

External Email - Use Caution Hi, Recently, I ran an analysis on Freesurfer and found increased cortical thickness on the patients compared to controls. Then, I heard about CAT12 and wanted to see if my results would be robust enough and be replicated using this other software. When I ran the analysis on CAT12, the results look completely different (both increased and decreases). I was not able to see the same clusters on the CAT12 results. I used the same subjects and covariates. I ran recon-all using both T1 and T2 images, whereas in CAT12 you can only use T1 images. Has anyone experimented with both software before? Best, Omar

issue with lesions
by Sam W 25 Sep '19

25 Sep '19

External Email - Use Caution Hello, I have run recon-all on T1 scans of patients with WM lesions. I noticed however that for some patients the lesion is excluded from aparc.a2009s+aseg.mgz but for other patients it is included (and labelled as non-lesion). Ultimately I'd like to extract a) volume information in WM and b) volume information of the WM lesion. I think I can get the the WM volume from the wmparc.stats file. For the lesion volume I think I can take the WM-hypointensities from the aseg file right? However I noticed that if a lesion is on the right hemisphere, the Right-WM-hypointensities shows 0s in all columns, which cannot be right. I have a mask of the lesion (1s where lesion occurs, 0s elsewhere) in anatomical space, can I use this mask somehow in FS to inform recon-all where the lesion occurs? Thanks in advance! Sam

External Email - Use Caution Hello Samer, The git bash shell on Windows will not be sufficient to run freesurfer programs on Windows.  Freesurfer is supported on CentOs Linux, Ubuntu Linux and MacOS.  However, some folks use the Ubuntu shell as supported on Windows 10.  This does work once setup in Windows and after some packages have been added to the Ubuntu image.  I have not used the Ubuntu shell on Windows very much, but you can read about installing and using it via the links below. - R. http://www.techken.in/linux/how-to-run-gui-ubuntu-linux-in-windows-10/ https://christopher5106.github.io/admin/2018/02/02/configure-windows-10-for… Samer Muhareb September 24, 2019 at 13:37         External Email - Use Caution        Hello, I am having trouble adding Freesurfer onto my PC. I have the program downloaded, but when I attempt to input a command from the Freesurfer program, it tells me that my command was not found.  This is my first time downloading a program to use in the command line without it being done for me, so I am not super clear on how to go about solving this issue or may have missed a crucial step. I was suggested to add the program onto the path but I am not really sure how to do that.  Any ideas or suggestions will be very helpful! I am using git bash on my windows, if that is helpful Thanks for taking the time to look into this, it is greatly appreciated.  Best,Samer Muhareb  _______________________________________________ Freesurfer mailing list Freesurfer(a)nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer

help! Hippocampal subfield segmentation with FS development version
by Liwen Zhang 24 Sep '19

24 Sep '19

External Email - Use Caution Hello freesurfer experts, I previously applied hippocampal subfield segmentation using FS v.6.0. I am now trying to devide subfields into head/body where applicable using FS development version (latest version). However, I encountered the following problems/quesetions: 1) X represents certain subfield (volume)X_head + X_body (from FS dev) ~= X (from FS v.6.0) What possibly causes this volume discrepancy between FS dev and FS v.6.0? Is the head/body segmentation template in FS dev based on the same ex-vivo template as used in FS v.6.0? 2) Related to 1), subfield volume as obtained from FS v.6.0 generally larger than that from FS dev (not for all subfields though) I processed T1 images with FS v.6.0 and then applied hippocampal segmentation with both FS v.6.0 and FS dev. Any suggestions/comments would be greatly appreicated! Thank you for your time and help in advance! Best, Liwen

DPABISurf V1.2 Is Released
by YAN Chao-Gan 23 Sep '19

23 Sep '19

External Email - Use Caution Dear Colleagues, We are pleased to announce the release of DPABISurf V1.2! 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 fMRIPprep 1.5.0 (Esteban et al., 2018)(RRID:SCR_016216), and based on FreeSurfer 6.0.1 (Dale et al., 1999)(RRID:SCR_001847), ANTs 2.2.0 (Avants et al., 2008)(RRID:SCR_004757), FSL 5.0.9 (Jenkinson et al., 2002)(RRID:SCR_002823), AFNI 20160207 (Cox, 1996)(RRID:SCR_005927), SPM12 (Ashburner, 2012)(RRID:SCR_007037), PALM alpha112 (Winkler et al., 2016), GNU Parallel (Tange, 2011), MATLAB (The MathWorks Inc., Natick, MA, US) (RRID:SCR_001622), Docker (https://docker.com) (RRID:SCR_016445), and DPABI V4.2 (Yan et al., 2016)(RRID:SCR_010501). DPABISurf provides user-friendly graphical user interface (GUI) for pipeline surface-based preprocessing, statistical analyses and results viewing, while requires no programming/scripting skills from the users. <http://www.rfmri.org/dpabi> The DPABISurf pipeline first converts the user specified data into BIDS format (Gorgolewski et al., 2016), and then calls fMRIPprep 1.5.0 docker to preprocess the structural and functional MRI data, which integrates FreeSurfer, ANTs, FSL and AFNI. With fMRIPprep, the data is processed into FreeSurfer fsaverage5 surface space and MNI volume space. DPABISurf further performs nuisance covariates regression (including ICA-AROMA) on the surface-based data (volume-based data is processed as well), and then calculate the commonly used R-fMRI metrics: amplitude of low frequency fluctuation (ALFF) (Zang et al., 2007), fractional ALFF (Zou et al., 2008), regional homogeneity (Zang et al., 2004), degree centrality (Zuo and Xing, 2014), and seed-based functional connectivity. DPABISurf also performs surface-based smoothing by calling FreeSurfer’s mri_surf2surf command. These processed metrics then enters surfaced-based statistical analyses within DPABISurf, which could perform surfaced-based permutation test with TFCE by integrating PALM. Finally, the corrected results could be viewed by the convenient surface viewer DPABISurf_VIEW, which is derived from spm_mesh_render.m. <http://www.rfmri.org/dpabi> DPABISurf is designed to make surface-based data analysis require minimum manual operations and almost no programming/scripting experience. We anticipate this open-source toolbox will assist novices and expert users alike and continue to support advancing R-fMRI methodology and its application to clinical translational studies. DPABISurf is open-source and distributed under GNU/GPL, available with DPABI at http://www.rfmri.org/dpabi. It supports Windows 10 Pro, MacOS and Linux operating systems. You can run it with or without MATLAB. 1. With MATLAB. 1.1. Please go to http://www.rfmri.org/dpabi to download DPABI. 1.2. Add with subfolders for DPABI in MATLAB's path setting. 1.3. Input 'dpabi' and then follow the instructions of the "Install" Button on DPABISurf. 2. Without MATLAB. 2.1. Install Docker. 2.2. Terminal: docker pull cgyan/dpabi 2.3. Terminal: docker run -d --rm -v /My/FreeSurferLicense/Path/license.txt:/opt/freesurfer/license.txt -v /My/Data/Path:/data -p 5925:5925 cgyan/dpabi x11vnc -forever -shared -usepw -create -rfbport 5925 /My/FreeSurferLicense/Path/license.txt: Where you stored the FreeSurferLicense got from https://surfer.nmr.mgh.harvard.edu/registration.html. /My/Data/Path: This is where you stored your data. In Docker, the path is /data. 2.4. Open VNC Viewer, connect to localhost:5925, the password is 'dpabi'. 2.5. In the terminal within the VNC Viewer, input "bash", and then input: /opt/DPABI/DPABI_StandAlone/run_DPABI_StandAlone.sh ${MCRPath} Now please enjoy the StandAlone version of DPABISurf with GUI! If you don't want to run with GUI, you can also call the compiled version of DPABISurf_run. E.g., docker run -it --rm -v /My/FreeSurferLicense/Path/license.txt:/opt/freesurfer/license.txt -v /My/Data/Path:/data cgyan/dpabi /bin/bash /opt/DPABI/DPABI_StandAlone/run_DPABISurf_run_StandAlone.sh ${MCRPath} /data/DPABISurf_Cfg.mat New features of DPABISurf_V1.2_190919 within DPABI_V4.2_190919 (download at http://rfmri.org/dpabi, please also update the docker file by: docker pull cgyan/dpabi): 1. DPABISurf_V1.2_190919 updated. 1.1. A quality control module was added to DPABISurf. Now users can quality control surface reconstruction, EPI to T1 registration and T1 to MNI registration for all the subjects in one HTML file, respectively (based on fmriprep 1.5.0). For volume-based analysis, users can also generate group mask for DPABISurf, and exclude subjects by thresholding coverage and head motion. 1.2. DPABISurf now also output sulcus depth and volume in fsaverage and fsaverage5 spaces for statistical analysis. 1.3. In results organizer of DPABISurf, the redundant files would not be organized now. In addition, the fmriprep and freesurfer files were backed up, while excluding T1 image that may have privacy information such as face. 2. DPABI_VIEW has a new function "Surface View with DPABISurf_VIEW" now. This function will convert the files to fsaverage surface using freesurfer's mri_vol2surf command. Then the results were displayed by calling DPABISurf_VIEW to generate surface-based picture. Tips: 1) For Linux or Mac OS, please start matlab from terminal in order to reach docker in DPABI (e.g., Linux: matlab; Mac: open /Applications/MATLAB_R2018a.app/). 2) Before running DPABISurf_Pipeline, you can test the docker environment by running DPABI->DPABISurf->Utilities->Volume-Surface Projector. If the file can be successfully projected to surface, then the software is all set. References: - Ashburner, J. (2012).

External Email - Use Caution Hello, with Qdec, there was an option to "remove" positive (or negative) results from the displayed overlay... Is it possible to do something similar with the results of mri_glmfit, but displaying with freeview instead? For instance, if I wanted to exclude regions that appear to have increased cortical thickness when compared to healthy controls? Thanks, Eli Houston Methodist. Leading Medicine.

Keep manual edits of older freesurfer versions?
by Joëlle Ismay Rosanne Van Der Molen 23 Sep '19

23 Sep '19

External Email - Use Caution Dear FreeSurfer experts, I have a question regarding manual edits and change of FreeSurfer version. In our lab, we have thus far processed most of our T1 scans using FS version 5.1 and have performed manual edits when needed. We are now updating our processing to FS version 6.0, and would like to use previously edited data (from the 5.1 version) as an input for the FS version 6.0 processing (based on previous emails from the mail archive, I understand this makes sense?). Ideally, I'd like to store the FS6 outputs in a new parent directory (different from the directory where the FS5.1 processing outputs are stored). However, simply running: recon-all -s subject_name -sd /path/to/FS6_outputs/ -all ... with /path/to/FS5.1_outputs/ as a SUBJECTS_DIR doesn't work (it looks for input data in the -sd specified output directory, which doesn't contain anything yet). Adding an -i flag with a full path to the desired output directory also doesn't work: recon-all -s subject_name_FS6 -sd /path/to/FS6_outputs/ -i /path/to/FS5.1_outputs/subject_name/ ... as it says the -i flag needs a file as an input, not a folder. Now, adding an -i flag and giving for instance the 001.mgz as input works: recon-all -s subject_name_FS6 -sd /path/to/FS6_outputs/ -i /path/to/FS5.1_outputs/subject_name/mri/001.mgz However, if I am not mistaken, the manual edits are not stored in this 001.mgz file. Thus, does this mean that when rerunning a new version of freesurfer on already processed data, the same subject folder has to be used as input (FS 5.1 processed data) and output (FS 6 processing outputs)? And if so, should old files (that remain non-modified after the FS6 run) be removed? Thank you in advance for your answer, Best regards, Joëlle van der Molen
