Re: [Freesurfer] Guidance on SegmentHA with Low-Res MRI

2025-04-04 Thread Iglesias Gonzalez, Juan E.
Dear Nima, Thanks for the interest in our work. I don’t know if I would advise trying to segment these small subregions from such thick slices. But if you are set on doing that, I would probably run SynthSR first, and work with the synthetic 1mm isotropic T1s. You can run SynthSR on the T1s and

[Freesurfer] Guidance on SegmentHA with Low-Res MRI

2025-04-04 Thread Taghizadeh Mortezaei, Nima
Dear FreeSurfer Community, I’m currently working with clinical MRI data and would appreciate your guidance regarding two issues I'm encountering with hippocampal/amygdala segmentation (segmentHA_T1.sh script). My available T1w and T2w scans both have 6 mm slice thickness and are anisotropic and

Re: [Freesurfer] synthstrip use as a Docker for all MRI files in directory

Hi Ivan, Thank you for your interest in SynthStrip. A Dockerfile is only executed once, when you build ("compile") the container, not when you run it. You may want to consider writing a simple Python or shell script that loops over your files and calls the existing container on each. Do you ha

Hi Stefanie The registration is based on the curvature of the smoothwm surface (among other things) so not easily. Lilla might know more about that atlas. Bruce From: freesurfer-boun...@nmr.mgh.harvard.edu On Behalf Of Stefanie Bradley Sent: Monday, March 31, 2025 4:35 PM To: freesurfer@nmr.m

[Freesurfer] LME ROI group analysis

2025-04-04 Thread Bondi, Daniel
External Email - Use Caution Hi FreeSurfer experts, I am using the univariate LME pipeline (lme_fit_FS & lme_F) to conduct cortical thickness analysis on a subset of D-K atlas ROIs between two groups. Although I am testing longitudinal group*time differences with this pipeline,
