Intensity affected after using -c flag in mri_convert
by ERNEST KISSI 11 Jun '24

11 Jun '24

External Email - Use Caution Dear fresurfer team, Why does the use of conform flag (-c) in mri_convert affect the intensity of the image? I have an image with absolute intensity of 1000 and after using the conform flag in mri_convert, the intensity is around 98.1. why is there a different scale in the intensity after the use of the flag?

Transformed geometry does not match
by Yasmine Salman 11 Jun '24

11 Jun '24

External Email - Use Caution Dear FreeSurfer developers, I am trying to run longitudinal recon-all -long command. For some subject the recon-all -long command does not work and the error message indicate that 'transformed geometry does not match". I checked and the initial recon-all finished without error as well as the recon-all -base. I also tried to re-run de base but it does not help. Knowing that recon-all -long command worked for the majority of my subjects, what can explain that it does not work for some of them ? And how can we solve that problem ? Thanks in advance for your help, Best, Yasmine

Issue with cortical data extraction for mkanalysis-sess
by O'Dor, Sarah 11 Jun '24

11 Jun '24

We are trying to run resting state connectivity analyses using amygdala ROI. The left hemisphere ran fine, but for the right hemisphere, something is clearly off. When we export the results into a table, the unknown column, which should be zero, has values, and one of the regions instead has zeroes. It’s as if something is shifted, but we’ve checking the coding. Briefly, the commands we used were mri_vol2vol, fcseed-config, fcseed-sess, mkanalysis-sess, selxavg3-sess, mri_glmfit, mri_segstats. Any ideas on where/which commend we should be troubleshooting? We’ve run it twice and gotten the same results. Thanks, Sarah

negative values converting mgz files to nifty
by Nina Rouhani 11 Jun '24

11 Jun '24

External Email - Use Caution hello! after freesurfer segmentation (through fmriprep v23), i converted the aparc+aseg.mgz file into a nifty file using the below code (freesurfer v7.4.1): -rl $fs_dir/mri/rawavg.mgz -rt nearest $fs_dir/mri/aparc+aseg.mgz $sub_dir/rois/anatomical/aparc_aseg2mprage.nii.gz however, the voxel values of the aparc_aseg2mprage.nii.gz range between 31000-32000 and -31000- -32000. consequently, the label values for particular regions no longer correspond to what’s in the freesurfer manuals (like those listed here: FsTutorial/AnatomicalROI/FreeSurferColorLUT - Free Surfer Wiki <https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI/FreeSurf…> ). would be incredibly grateful if i could be pointed to what i’m missing or what could be going wrong! thank you!

Bug in mri_convert reslice-like with 4D images
by Iglesias Gonzalez, Juan E. 11 Jun '24

11 Jun '24

Dear FS experts, We get a segfault when I try to resample images with the command: mri_convert input.mgz output.mgz -rl reference.mgz when reference.mgz has multiple frames (e.g., a RGB volume). Any idea of why this is happening? Cheers, /Eugenio (&Stefano & Pranav)

INTERNATIONAL CONFERENCE ON ARTIFICIAL INTELLIGENCE IN HEALTHCARE (AIiH)
by Jiaxiang ZHANG 11 Jun '24

11 Jun '24

External Email - Use Caution [apologies for cross-posting] *INTERNATIONAL CONFERENCE ON ARTIFICIAL INTELLIGENCE IN HEALTHCARE (AIiH)* 4 - 6 September 2024, Swansea, UK https://aiih.cc (*2nd CALL FOR ABSTRACT*) Submission deadline: Monday 1 July (FIRM) *1. INTRODUCTION * https://aiih.cc/abstracts/ AIiH 2024 welcomes late-breaking short abstract submissions to be included as poster or short spot-light presentation at the conference. This is to both enable fast dissemination of promising preliminary findings and encourage attendance by a broader audience of early career researchers (including research students), healthcare professionals, and industrial practitioners. AIiH 2024 is a single-track conference with oral and poster presentations and will include a conference tutorial on generative DNNs and 5 keynote presentations. The conference will also feature a plenary session, which consists of 3 invited speakers who have extensive experience in related areas. AIiH aims to provide a prominent platform for researchers and practitioners who are devoted to improving healthcare using modern artificial intelligence. We recognise that healthcare applications present complex and sometimes unique challenges across a wide spectrum, from ethics to technical developments, that generic AI methods are often inadequate. By creating this dedicated forum, we encourage discussions and disseminations of efficient and effective AI solutions and technologies for healthcare, and in turn we hope to influence the research, technology adoption, and decision making in healthcare. *2. CONFERENCE TUTORIAL* Title: Deep Generative Neural Networks https://aiih.cc/tutorial-generative-dnn/ Dr. Amir Atapour-Abarghouei University of Durham *3.

Incoporating synthstrip and synthseg into recon-all
by Dan Levitas 07 Jun '24

07 Jun '24

External Email - Use Caution Hello, I am using freesurfer version 7.4.1, and would like to incorporate the recently introduced synthstrip and synthseg functions into my recon-all command, if that's possible. From this archive message ( https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg75148.html) it seems that adding the -synthstrip option enables synthstrip; however, I don't see this as an option in the recon-all documentation ( https://surfer.nmr.mgh.harvard.edu/fswiki/recon-all) nor as a command line option for recon-all. Assuming that both synthstrip and synthseg can be used in recon-all, would the command need to look something like this: *recon-all -subjid sub-${sub}_ses-${ses} -i $anat_file -3T -synthstrip --no-csf -synthseg -qcache -all* I'm adding the *--no-csf* synthstrip option based on this comment ( https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg75172.html) I should also note that I'm performing a longitudinal analysis, so this specific recon-all pertains to the cross-sectional portion of the workflow. Thanks, Dan

External Email - Use Caution  It could help to see the core dump file.  If you are on a Mac it will probably display it.  If you are on Linux and you have core dumps enabled on the system, then you have to look in the logs. - R.

Freesurfer license
by Ayoub, Lizbeth 04 Jun '24

04 Jun '24

Hi, I am using singularity to run fmriprep, and it seems that it is not recognizing the location of my freesurfer license ( it is a new license). I have tried all three options for location, and none work: ERROR: a valid license file is required for FreeSurfer to run. fMRIPrep looked for an existing license file at several paths, in this order: 1) command line argument ``--fs-license-file``; 2) ``$FS_LICENSE`` environment variable; and 3) the ``$FREESURFER_HOME/license.txt`` path. Get it (for free) by registering at https://surfer.nmr.mgh.harvard.edu/registration.html I appreciate any insights on how to fix this error :) Thank you so much, Liz
