fspalm issue
by Isabelle Ye 13 Nov '19

13 Nov '19

External Email - Use Caution Hi FreeSurfer community, I’m using fspalm to correct multiple comparisons for vertex-based cortical thickness analysis. It ran successfully and several clusters survived after correction for multiple comparisons. Below is the code I used for permutation tests. fspalm --glmdir cth.glmdir --cft 4 --onetail --name palm-onetail-4 --iters 1000 --2spaces --cwp .05 After that, I would like to generate a surface map after permutation tests, which stores the original surface values except that vertices not assigned to a cluster are set to 0. I checked the fspalm and mri_surfcluster description but did not find any clue. I also tried to run the analysis below but I could not adjust the threshold of the output file (contrast.surfvalues.mgz) because it seems to be a binary file . mri_surfcluster --in fsp_clustere_tstat_fwep.mgz --thmin 1.301030 --subject fsaverage --hemi lh --annot aparc --no-fixmni --surf white --ocn contrast.ocn.mgz --oannot ./contrast.ocn.annot --sig2p-max --bonferroni-max 2 --o ./contrast.surfvalues.mgz Any help would be appreciated. Thanks, Isabelle

Freesurfer6.0 hippocampal and amygdala segmentation-command not found error
by Isabella Leung 13 Nov '19

13 Nov '19

External Email - Use Caution To whom it may concern, I am trying to run hippocampal and amygdala segmentation https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldsAndNucleiOfAm… I was able to run recon-all, however I am unable to run segmentHA_T1.sh and get the error message of "command doesn't exist". I'm not quite sure what the problem is. I have seen online that I should update the freesurfer to the development version? I'm not sure how to update my Freesurfer 6.0 to the development version. Could you please let me know how I can update my freesurfer 6.0 so that I can run segmentHA_T1.sh? I have run recon-all on all my participants through Freesurfer 6.0. Will it mean that I will have to redo my recon-all in the freesurfer development version for all my participants before I try to run the segmentHA_T1.sh? Thank you in advance for the help.

Recon all hard failure,
by Vicente Ferrer 13 Nov '19

External Email - Use Caution Hello, I was runnning reconall in one of my images and it got stucked fixing surface defects, since i run it on a cluster it stopped when it runned out from cpu time. As you will see in the log the command started in SUNday 16 14:59:32 CEST 2019 and ended in Mon Jun 17 05:10:16 CEST 2019 which is more than usual for a recon-all duration. I have checked some of the previous images and there is clearly an alignment problem as you can check in this image: Vicente Ferrer Predoctoral Researcher BCBL www.bcbl.eu Legal disclaimer/Aviso legal/Lege-oharra: www.bcbl.eu/legal-disclaimer

Postdoctoral Researcher Position in Neuropsychology/Imaging/Genetics at UCSD
by Andrews, Murray 12 Nov '19

12 Nov '19

External Email - Use Caution Postdoctoral Researcher in Neuropsychology/Imaging/Genetics The Human Memory Lab at UCSD is looking for an outstanding postdoctoral researcher to join the team as soon as possible. The researcher will work primarily with Dr. Sarah Banks on a study of sex differences in Alzheimer’s disease using preexisting data. The study utilizes cutting edge neuroimaging and analytic techniques involving tau PET and also MRI to assess cross-sectional and longitudinal patterns of sex differences in tau, and how they relate to cognition and genetics. In addition to Dr. Banks, the researcher will work extensively with collaborators, including Drs. Jim Brewer, Anders Dale, Linda McEvoy, Chun Chieh Fan and Steve Edland. The ideal candidate will hold a PhD in neuroscience, psychology or similar and have an interest in and experience with neurodegenerative disease, cognition, and neuroimaging. Background in research with Alzheimer’s disease is beneficial, but not mandatory. He or she will enjoy working in a multidisciplinary team, be productive and enjoy contributing to every stage of analysis and presentation. He or she will hit the ground running, working on already existing datasets to answer research questions related to those posed in the grant, and also develop their own projects. There will also be the opportunity to work on prospective data currently being collected using tau PET in participants with Alzheimer’s disease. In addition to image analysis and statistical knowledge and ability, great writing and communication skills will be important. UCSD provides a superlative environment to jump start an academic career, especially for those interested in Alzheimer’s and neuroimaging. There will be plenty of opportunities to broaden academic horizons through seminars across the campus, and the Banks Lab, while relatively new, has established multiple cross-disciplinary collaborations. The Banks Lab is housed within the Human Memory Lab, and thus benefits from being a new, growing lab within a more established infrastructure. Please send your CV to sbanks(a)ucsd.edu<mailto:sbanks@ucsd.edu>. If you have any questions regarding the position, please do not hesitate to contact Dr. Banks directly.

External Email - Use Caution Dear Developer, I am learning the FaFast to analyse the fMRI data. I have a question about the sunjectname file, I created a text file under the Sess06 file, like this: The content of the subjectname file is 'f06'. I created a file called fsl_bold including my anatomical data Then, I runned this preprocessing command: export SUBJECTS_DIR=/Users/qianqianyu/Desktop/fsl_bold cd /Users/qianqianyu/Desktop/preject_try preproc-sess -s Sess06 -vol-fwhm 4 -fsd bold -per-run There was a error!!! I do't know how to solve this error, so I hope I can get your help. Beat wishes to you! Looking forward to your reply！ qianqianyu 2019.11.12

4D multi-frame parcellation
by 曲岸 12 Nov '19

12 Nov '19

External Email - Use Caution Hi there, I am working with creating a surface parcellation from a volumetric parcellation and have some questions as follows: 1. If the volumetric parcellation is a labeled 4D multi-frame dataset, could I still use the mris_sample_parc? Or could mri_vol2surf get the sampled labels for every vertex? 2. For the 4D multi-frame dataset and mri_vol2surf output results, which GUI should I use to visualize it? I tried freeview for 4D multi-frame dataset but it looks weird. 3. Is there any command to separate multi-frame volume to single frame volumes? Many thanks! Best, An
