Vertex / voxel lesion symptom mapping
by Martin Juneja 03 Mar '24

03 Mar '24

External Email - Use Caution Greetings FreeSurfer community, I was just wondering if it's possible to perform vertex/voxel lesion symptom mapping (VLSM) using FreeSurfer? In other words, I would like to assess the impact of lesion topography (of course, heterogenous locations across patients) on neurocognitive function in brain tumor patients. I would greatly appreciate any help/response. Thanks!

Samseg (cross-sectional, longitudinal, MS lesions)
by Krzysztof Barć 01 Mar '24

01 Mar '24

External Email - Use Caution Good morning, 1) For the Samseg protocol, are only T1 and FLAIR sequences required (no MPRAGE scans required)? 2) What does the numerical output of the Samseg calculation look like? Best regards, Krzysztof Barć

Creating a custom registration template with FreeSurfer template
by Asuka Toyofuku 29 Feb '24

29 Feb '24

External Email - Use Caution Dear Freesurfer experts, I have issues with creating a custom registration template. (I'm following this instruction: https://secure-web.cisco.com/1_qfYxT5WNAR-lGRNh895Kl4pqE513hIRdGqZt0w-oDRR8… ) According to the instructions, we need to 1) Create an average subject (Creates $SUBJECTS_DIR/newtemplate) 2) Register each subject to the new template (do for both lh and rh), resulting in lh.sphere.reg.newtemplate and rh.sphere.reg.newtemplate 3) Get thickness values in the newtemplate space for GLM analysis 4) Create another average template based on the previous one: (Creates $SUBJECTS_DIR/newnewtemplate) I'm stuck with the 3) command. Instruction suggests: mris_preproc --surfreg sphere.reg.newtemplate --s subj1 --s subj2 --s subj3 ... and this is my code: for d in Teen* do mris_preproc --surfreg sphere.reg.teenheart_average_template --s $d --hemi lh --out lh.surfreg.teenheart_average_template.thickness --meas thickness done ( I specified hemi and output because, without it, I got ERROR: no source hemi specified) My command led to an error saying: ERROR: format for lh.surfreg.teenheart_average_template.thickness not recognized So my questions are: a) what does it mean that "format for lh.surfreg.average_template.thickness not recognised"? Any ideas on how to fix this? b) Does this mris_preproc --surfreg command produce different smoothing mgh files? (e.g., fwhm10, fwhm15, fwhm20...?) Because standard mris_preproc before GLM analysis(https://secure-web.cisco.com/1lH2n5girv1pSO3WmL3I9nDeL07oFU0ViiAmz… are done with previously qcashed data (e.g., need thickness.fwhm10.fsaverage to run mris_preproc), but at this point, I don't have any of these thickness files with different smoothing levels. c ) If this mris_preproc --surfreg command does not generate a set of thickness maps in **newtemplate space** at different smoothing levels, what kind of command should I run? Any input is appreciated! Best regards, Asuka

External Email - Use Caution We are pleased to announce "*Thalamocortical networks (ThalNet): Bringing together cellular and cognitive neuroscience*", which will take place in person this *May 16-17 *at the Miramar Palace in *Donostia–San Sebastián*: https://secure-web.cisco.com/1OS0_akv0X2OFqkClRNexoTXkrzp2IxsLrRHYZLD531M4n… To understand thalamic function and structure represents a formidable neuroscientific challenge, wherein the collaboration between cellular and cognitive neuroscientific approaches holds much promise. Recognizing the potential synergy between these two disciplines, ThalNet is aimed at convening world experts from both realms and at setting the bases to initiate, foster, and develop interactions among researchers from these fields to further advance and strength our understanding of thalamocortical and corticothalamic networks. We look forward to welcoming you to Donostia-San Sebastián and to this exciting scientific event, which includes world renowned speakers on the topic.

Too large volumes thalamus segmentation in version 7.2
by Katharina von Kriegstein 27 Feb '24

27 Feb '24

Dear List, We are using the thalamic segmentation and have encountered too large nuclei volumes. We are aware of the bug in previous Freesurfer versions reported here https://secure-web.cisco.com/1IbBjsoyLKSxbo51anCmnlGJ7AZlAHQC-iMHoutsQKt5em… . In version 7.2 this bug is fixed. Does someone else have similar difficulties with too large volumes? For example, our LGN is 259 mm3 (left) and 304 mm3 (right), while in the original paper for the thalamus segmentation (Iglesias et al. 2018), it is 124 mm3, which is close to the size reported by histological studies. Thanks for reading!

recon all with optiBET brain mask
by BALBONI Irene 27 Feb '24

27 Feb '24

External Email - Use Caution Hello, I would like to run recon all on a batch of subjects using 2 inputs (mprage and mp2rage). I would also like to run recon all using as brain mask not the standard brain mask generated by recon-all itself but a previously created optiBET. Would you have any suggestion on how to proceed? I tried simply replacing the brainmask file with the optiBET but it did not work. Just for context all my participants (150) have been already segmented using recon-all but we noticed during quality control that we still have skull stripping and pial surface errors for the majority of them and that is why we would like to implement the optiBET mask.
