Postdoc Position for Human Intracranial EEG Lab
by Winfield, Jalen 12 Jul '23

12 Jul '23

External Email - Use Caution Dear all, Please find enclosed Post-Doctoral position that may be of interest. * Funding Duration: 4-5 years * Start Date: As soon as possible * Research Team: Laboratory for Human Brain Mapping at the Feinstein Institute for Medical Research - Hofstra Northwell School of Medicine, NY, USA * Application: Interested candidate should send CV, names and contact info of 2-3 references, and any questions to Stephan Bickel, MD PhD (sbickel(a)northwell.edu<mailto:sbickel@northwell.edu>) This post-doc position is part of a large, recently funded NIH multi-center project to investigate the functional role of slow fluctuating cortical activity. These slow fluctuations are a ubiquitous and fascinating feature of brain activity and is thought to play a crucial role in many cognitive functions from attention, interoception, state switching, etc. This is an extremely collaborative project among a large amount (>25 PIs) of international leaders in the field using scalp EEG, fMRI, iEEG, and single unit recordings in humans and animal models, electrical stimulation, and computational modeling. The candidate will have ample opportunities to work closely with these collaborators. Additionally, the candidate is encouraged to help mentor/supervise research assistants.

Indices out of bounds error during mri_watershed

12 Jul '23

External Email - Use Caution Hi all, I am running into an error running recon-all and I can't figure out what's going on just from the error messages. I'm hoping someone here can help. I'm using FreeSurfer 7.2 and this is the command I'm trying to run: recon-all -subjid HCA6429272_V1_MR -i /autofs/space/yoda_002/users/datasets/HCA/data/as_downloaded/HCA6429272_V1_MR/scans/110-T1w/resources/NIFTI/files/HCA6429272_V1_MR_T1w_MPR_vNav_4e_RMS.nii.gz -all build stamp: freesurfer-linux-centos7_x86_64-7.2.0-20210720-aa8f76b operating system: cat /etc/centos-release Rocky Linux release 8.8 (Green Obsidian) I've run about 1200 recons in the last few weeks from the same dataset using analogous commands for the other T1s, but this is the only one that failed. The T1 isn't great quality, but not terrible either (screenshot below). The error happens during the watershed step: "mri_watershed Error: indices out of bounds". I've attached the log and error file from the recon. Thanks for any help you can provide. Best, John Screenshot of the input T1: [cid:173163e6-208e-4800-a256-55aed18f186d]

Matrix setup to examine group effect between three groups, one covariate (age) as nuisance variable
by Gavette, Levi William 12 Jul '23

12 Jul '23

External Email - Use Caution Hello FreeSurfer community, I am looking to perform a GLM between three groups with the single covariate of age as the nuisance variable. I am wondering how to set up my matrix design so that the output will be the group difference with age removed? Any help is really appreciated. Thanks, – Levi

[FreeSurfer] Talairach Failure Detection
by Krystal Xiwing Yau 12 Jul '23

12 Jul '23

External Email - Use Caution Dear Freesurfer experts, I would like to seek for help regarding talairach error. I have browsed through the forum about it but still not solving my problem... The following steps are the solutions I have tried: * Re-run recon-all with -notal-check * Re-run recon-all with -notalairach * The above flags gave the same error message as follow: * WARNING2: gca.c::GCAhistoScaleImageIntensities: h_mri->nbins=100, mri_peak=108 after smoothing, mri peak at 0, scaling input intensities by inf error: Numerical result out of range error: GCAhistoScaleImageIntensities: could not find wm peak Command exited with non-zero status 252 * Ran the command to fix the registration: tkregisterfv --s Sub-108 --fstal --no-surfs * The view for this subject is weird because it shows the axial view when the coronal view is selected * [cid:49cf1b63-a35e-4003-8f38-a1def3b7bd64] * The correct view showed up when the coronal view is selected * [cid:abd68344-6bc3-489a-9eef-20569a419c02] When I viewed 001.mgz in Freeview, there was no such problem. However, some artifact (i.e. the weird lines) occurred in certain slices, as circled in pink: [cid:0c0b2ea4-3b3e-4361-ad0c-c5dec191c85c] [cid:eadbe192-c57a-48db-b429-b162b0154d0f] [cid:229941cf-2005-44c6-a979-0bf60c03da18] I am not sure how to fix it with tkregisterfv and what are the standards for it. It would be so much appreciated if someone could help out with this issue.
