Postdoctoral position in Neuroimaging and Aging at Albert Einstein College of Medicine
by Mark Wagshul 12 Oct '23

12 Oct '23

External Email - Use Caution Postdoctoral position in Neuroimaging and Aging at Albert Einstein College of Medicine A postdoctoral research fellow position is available immediately in the departments of Neurology and Radiology at the Albert Einstein College of Medicine in NY. The position will offer unique opportunities to utilize multi-modal neuroimaging data collected on normal and neurological populations that are well characterized in terms of cognitive, motor, and emotional function. The post-doctoral fellow will be expected to devote significant time and effort to writing empirical research articles. In addition, there will be opportunities to learn and become involved in collecting, processing, and analyzing novel neuroimaging data combining different methods (MRI, fNIRS, EEG). We are seeking an enthusiastic and highly-motivated individual with experience in neuroimaging analysis methodologies. Experience and knowledge of aging and neurodegenerative diseases is desirable. Successful candidates will have a PhD in biomedical engineering, physics, computer science, cognitive neuroscience or related disciplines, and experience in conducting experiments and performing advanced data analysis with structural and/or functional MRI methods (e.g. DTI/NODDI, resting state). Candidates will have a solid background in relevant data processing packages (e.g., FSL, SPM, Freesurfer), programming in either Matlab, Python or similar environments and should be comfortable with data analysis in a Linux environment. The ideal candidate will also have familiarity with computational and statistical methods related to imaging analyses. A strong work ethic, excellent organizational and communication skills is expected as well as the ability to work in an interdisciplinary environment. Willingness to learn new techniques or software environments and a strong foundation in neuroanatomy is plus. Excellent writing skills, a good publication record, and ability to work independently will be strongly favorable. The Albert Einstein College of Medicine is an Equal Opportunity/Affirmative Action Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, protected veteran or disabled status, or genetic information. Einstein seeks candidates whose skills, and personal and professional experience, have prepared them to contribute to our commitment to diversity and excellence, and the communities we serve.

TRACULA Error: Subregion Segmentation aparc+aseg+thalnuc.nii.gz
by Eric Paul Kraybill 12 Oct '23

12 Oct '23

External Email - Use Caution To Whom it may concern, I am trying to troubleshoot an error during TRACULA preprocessing and the issue seems related to the creation of aparc+aseg+thalnuc.nii.gz. The subregion segmentation prior to trac-all -prep was successful and mri/ThalamicNuclei.v13.T1.FSvoxelSpace.mgz and other Thalamic Nuclei files were generated. In the archives I saw that three others have experienced a similar issue without a resolution in the thread. I am using FreeSurfer 7.3.2 on an iMac Pro with Ventura 13.6. I have attached the log file, log error, and my configuration file. Any help would be greatly appreciated, and I hope to hear from you soon. Thank you, Eric

External Email - Use Caution Hi there, I am a Master's student who is looking to segment the hippocampus and analyze diffusion data of the segments. I am trying to utilize the segmentation function with this command: segmentHA_T1.sh subj01 But I am met with this error saying that Matlab has crashed. The crash log is attached to this email. I have freesurfer version 7.1.1, running on MacOs 11.7.10. I have followed your website instructions to download Matlab R2014b. Following the installation process of Matlab, I was met with this message: Installing Product: MATLAB Compiler Runtime - Core 8.4 (Oct 08, 2023 11:29:15) Installing Product: MATLAB Compiler Runtime - GPU 8.4 (Oct 08, 2023 11:29:21) Notes: On the target computer, append the following to your DYLD_LIBRARY_PATH environment variable: /var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/tmp.aMmBemHB/install-target/v84/runtime/maci64:/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/tmp.aMmBemHB/install-target/v84/sys/os/maci64:/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/tmp.aMmBemHB/install-target/v84/bin/maci64: (Oct 08, 2023 11:29:21) Exiting with status 0 (Oct 08, 2023 11:29:21) End - Successful.

Comparison between groups
by Iara Senem 11 Oct '23

11 Oct '23

External Email - Use Caution Hello! I'm a beginner on FS, hope you can help me. I already ran recon-all and I got aseg and aparc stats into an Excel spreadsheet. Using statistical software (SPSS) I found some differences between controls and patients in some cortical thickness regions. I'd like to know how I can put those differences in a picture. How can I analyze the differences between these groups and get an image on Freeview? Thank you. -- ____________________________________________________ Iara Senem Doutoranda da FMRP-USP Departamento de Neurociências e Ciências do Comportamento da FMRP Neuropsicóloga/Psicóloga - CRP 06/142554 Fone: +55 (16) 98209-1817

Re: [Freesurfer] $FREESURFER_HOME/bin not being added to PATH (tcsh)
by fsbuild 10 Oct '23

10 Oct '23

External Email - Use Caution If you add these 2 commands to setup the freesurfer environment, e.g., for csh/tcsh as your default shell, $ setenv FREESURFER_HOME /usr/local/freesurfer/7.4.1-1$ source $FREESURFER_HOME/SetUpFreeSurfer.csh - to your shell initialization file, $HOME/.cshrc, then FREESURFER_HOME, SUBJECTS_DIR, PATH, etc., should automatically set/modified by source'ing SetUpFreeSurfer.csh when you open a new terminal window.   There is no need to subsequently set SUBJECTS_DIR or other freesurfer environment variables in your shell init file (or in the current terminal window session) unless the settings should be different than the defaults.  Most people add those 2 commands to be the last 2 lines in their shell init file. I would check the defaults set in the current shell environment using only those 2 commands above in your shell init file after opening a new terminal window, $ env | sort … and check FREESURFER_HOME, SUBJECTS_DIR, PATH are set … The freeview command should already be found in your path, i.e., you should see … $ which freeview/usr/local/freesurfer/7.4.1-1/bin/freeview - R.

Re: [Freesurfer] Hippocampus Segmentation Troubleshoot - Matlab crash
by fsbuild 09 Oct '23

External Email - Use Caution Please try using the Matlab runtime environment which can be installed directly into the freesurfer tree via a script we provide.  The runtime environment is free and requires no paid for Matlab license (since it does not include the Matlab compiler). For your existing install of freesurfer 7..1.1, the tested version of the Matlab runtime environment to install is R2014b (listed below as the version to use in the bash/zsh commands).  However, if you were to update to the current freesurfer 7.4.1 release, https://secure-web.cisco.com/1EbuUGpusH65Vnhqyq32iw8lhOzpyphG…, then you could use the more recent R2019b Matlab runtime. $ export FREESURFER_HOME=<your install path> $ cd $FREESURFER_HOME/bin $ sudo FREESURFER_HOME=$FREESURFER_HOME  ./fs_install_mcr  R2014b    <— change to R2019b if you end up using freesurfer 7.4.1 … answer y to any installer questions … The output from running that script will list what DYLD_LIBRARY_PATH should be set to.   Please make sure you have otherwise removed any references to your previous matlab environment from DYLD_LIBRARY_PATH, PATH, etc.  It might also work to add $FREESURFER_HOME/MCRv97/bin/glnxa64 to DYLD_LIBRARY_PATH but I would first try what the script prints out as the local paths on your machine. - R.
