Re: [Freesurfer] virtual disk image of freesurfer 7.1.1

External Email - Use Caution Hello Gonzalo, The virtual box setup on Mac and Windows is listed here, https://surfer.nmr.mgh.harvard.edu/fswiki/VM_67 The actual link to the compressed disk image file is, https://drive.google.com/file/d/1bPvF9m2z4yRDIOv51B5bihU1VN_o2J5x/… If you already know how to use virtualbox, then you can just create a new machine using the *.vdi file after downloading an unzipping the disk image (otherwise read thru the instructions for setting up virtualbox on Windows or Mac - it should work the same way to setup and run the virtual Ubuntu machine on a different Linux distribution like CentOS, Fedora, etc. ). That VM image has the 7.1.0 release however, so once you have the virtual machine up and running, just update it with the 7.1.1 archive found here, freesurfer-linux-centos7_x86_64-7.1.1.tar.gz - R..

Viewing labels in freeview

22 Sep '20

External Email - Use Caution Dear freesurfer mailing list, I generated my own label file from a linear mixed effects model and now I want to view this label file on the surface of fsaverage using freeview. I am able to load the surface and label files successfully from the command line using the following: freeview -f $SUBJECTS_DIR/fsaverage_mod/surf/lh.inflated:label=lh.volume.stack.R3B.fwhm20.lmem.final.200817.gender.FDR-0001.label However, once freeview is open and the label file is loaded, I cannot see the label displayed on the surface (screenshot attached). I am currently using freesurfer version 5.3.0. Can someone please tell me how to make the label file visible on the surface of fsaverage? Kind regards, Bronwyn Overs Research Assistant Neuroscience Research Australia Margarete Ainsworth Building Barker Street Randwick Sydney NSW 2031 Australia M 0411 308 769 T +61 2 9399 1725 [ http://neura.edu.au/ | neura.edu.au ] [ https://twitter.com/neuraustralia | Twitter ] | [ https://www.facebook.com/NeuroscienceResearchAustralia | Facebook ] | [ http://www.neura.edu.au/help-research/subscribe | Subscribe ]

Re: [Freesurfer] Hippocampal subfields error
by Emily K Clarke 21 Sep '20

21 Sep '20

External Email - Use Caution Hi Eugenio, No, I don't think so - we're running recon-all and using the hippocampal pipeline from FS 6.0. I bug tested with the FS 6.0dev version and found that that hippocampal pipeline worked okay, but since we're combining data with an older dataset we need to be able to extract the older hippocampal subfields, starting with the recon-all hippocampal subfields processing.

mri_glmfit-sim error CSDs have the same seed
by Meaghan Perdue 21 Sep '20

21 Sep '20

External Email - Use Caution Hello Freesurfer experts, We're receiving the following error message when trying to run mri_glmfit-sim: ERROR: CSDmerge: CSDs have same seed This only occurs when we try to run the permutation on the LH for thickness. We've been able to run the simulation successfully on LH surface area and RH thickness and area. How can we troubleshoot this problem? Thank you, Meaghan Perdue -- Meaghan Perdue she | her | hers PhD Student Developmental Psychology Neurobiology of Language University of Connecticut Bousfield A302 Visit my website <https://mvperdue16.wixsite.com/meaghanperdue>

Make BEM with corrected brainmask
by Kadwani, Manorama 21 Sep '20

21 Sep '20

Hi, Why does the "mri_watershed" function create a new brainmask? Is there a way to create BEM surfaces from an existing or already corrected brainmask? I had manually edited the brainmask during recon-all process. After the recon-all process completed, the pial surfaces looked good. But when I ran 'make_watershed_bem', the BEM surfaces came out incorrect. The function 'mri_watershed' re-created a brainmask with the same errors that I had corrected earlier. I saw there was a question on this topic already, but couldn't find answers: https://www.mail-archive.com/search?l=freesurfer@nmr.mgh.harvard.edu&q=subj… Thanks, Manorama

Functional connectivity preprocessing and seed analysis

Problem running infant FreeSurfer - failure to create symbolic link
by Fleur Warton 21 Sep '20

21 Sep '20

External Email - Use Caution Hi FreeSurfer team, I'm trying to run the infant freesurfer (version: freesurfer-infant-20200205 ) and get the following error: ln: failed to create symbolic link 'brain.nii.gz': Operation not supported The command I used was: infant_recon_all --s 002B --age 0 I think this may have to do with the fact that my subjects_dir is located on a server (not the computer I'm running FreeSurfer on), since when I ran the command with the subjects_dir located on my local computer it ran fine and completed without errors. Unfortunately for space reasons it isn't possible for me to do that for my entire dataset. Thanks, Fleur -- Fleur Warton
