External Email - Use Caution  Hello Matthew, Thanks for this info. If it is not too much work, just wondering if you could make a rough estimate or compute an average for the *total*memory* in use = (size of physical RAM in use by synthseg + size of all swap files resident on disk used by synthseg). - R.

Ubuntu in WSL on a 16 Gb machine by increasing the swap and memory allowed in WSL.  This is done through the .wslconfig file which is located in the %USERPROFILE% folder (e.g. C:\Users\username\).  I had to specify a swap size of 32 Gb and also specify that WSL is allowed to use 32 Gb (even though the system only has 16 Gb -- it will use swap space).Here is the .wslconfig file I used:-----[wsl2]#

Installation tensorflow: protobuf requires Python '>=3.7' but the running Python is 3.6.8
by Jong, J.J.A. (Joost) de 11 Aug '23

11 Aug '23

External Email - Use Caution Hello FreeSurfer Developers, I would like to run samseg with the lesion module, hence samseg is asking to install Tensorflow using the following command: fspython -m pip install tensorflow==1.13.1 However, when execute the command, I get the following error: protobuf requires Python '>=3.7' but the running Python is 3.6.8 The problem persists when create a conda environment and try to install tensorflow there. I cannot seem to work around this problem, as fspython version seems to be 3.6.8. Why does FreeSurfer come with a Python version that conflicts with a protobuf version required to install tensorflow 1.13.1? Looking forward to your ideas/suggestions!

Question about glmfit results and visualization by using Freeview
by inbal paran 11 Aug '23

11 Aug '23

External Email - Use Caution Dear FreeSurfer developers, Thank you for your response to my previous questions, I have a few more (I'm inexperienced with both Freesurfer and Linux): 1. Can I visualize my results after running mri_glmfit by using Freeview, such that the image shows cortical brain regions as well as subcortical brain regions on both hemispheres? If yes - how can I do that? 2. Is there a text file of the glmfit results that includes the correlation parameters, cluster size, significance/p-values? If yes - where can I find it? If not - how can I generate one? Thank you very much Inbal -- *Inbal Paran, M.PT <http://secure-web.cisco.com/1YZJEd4xAGXQnv0pIXxLgi_JVIUWn7hQJs_Lvjrak6I2_f9…>.* Schwartz Movement analysis & Rehabilitation Laboratory, Physical Therapy Department, Recanati School for Community Health Professions.

RA Position for Human Intracranial EEG Lab
by Winfield, Jalen 11 Aug '23

11 Aug '23

External Email - Use Caution Dear all, The human intracranial EEG Laboratory at The Feinstein Institutes for Medical Research - Hofstra Northwell School of Medicine in New York is looking for a research assistant with earliest start date in October 2023. The successful candidate will help with the lab's research into (1) improving the identification of functional and pathological brain regions in individuals suffering from epilepsy, (2) the neural mechanisms of cognition, and (3) characterization of macro-scale human brain networks. The lab works exclusively with patients being evaluated for epilepsy surgery using methods such as invasive stereo EEG and electrocorticography recordings (iEEG, ECoG), anatomical MRI, fMRI, DTI, and direct electrical brain stimulation. The responsibilities will include assisting with the collection and analysis of the aforementioned data, project management, assistance with grant applications and progress reports, help with analysis of neural and imaging data using existing scripts (Matlab, Python), further development of those scripts (depending on coding and signal processing proficiency), and helping to present lab findings at conferences and in journals. The relative weighting of responsibilities can be adjusted depending on the interest of the applicant. If there is interest, the RA will have a scientific project with dedicated time to work on. Past research assistants have presented their work at clinical and basic research conferences, co-authored publications, and are working on first-author publications. They have gone on to medical schools or PhD programs after spending 1-3 years in the lab. This unique position will expose the successful applicant to basic and clinical neuroscience as well as neurosurgery, neurology, and neuropsychology. The location of the institute allows living either in the suburban neighborhoods of Long Island or in vibrant Brooklyn or Queens. Some employees also commute from Manhattan. It is a great opportunity for recent post-bacs interested in medical school or graduate school in neuroscience/biomedical engineering. ------------- Qualifications ------------- Minimum: - B.A./B.S./B.E. in an appropriate discipline (e.g., neuroscience, psychology, biomedical engineering, computer science, physics) - 2-year commitment - Experience with at least one programming language (MATLAB, R, or Python) Desirable: - Prior experience working with neuroimaging, EEG/MEG, or brain stimulation data - Previous experience working with patients - Previous work in a research laboratory that shows evidence of independent scholarship, problem solving, and motivation For more information about the position please send your CV along with your questions to Dr. Stephan Bickel (sbickel(a)northwell.edu<mailto:sbickel@northwell.edu>).

Fundi of Sulci
by Bluye Demessie 11 Aug '23

11 Aug '23

External Email - Use Caution Dear FreeSurfers, I am hoping to do an analysis of DTI metrics within the WM at the fundi of sulci. I am working with FreeSurfer v7.4.1 and want to use the ?h.curv to isolate the bottom of the sulcus based on the most positive curvature. Since ?h.curv is not a surface but rather a scalar field, is it possible to map ?h.curv to a volume in NIfTI format that can be overlayed on the original input NIFTI file with T1-weighted images used to produce the curvature map? Sincerely, Bluye
