recon-all -hires
by Nasiriavanaki, Zahra 22 Feb '19

22 Feb '19

Dear Freesurfer experts I was running recon-all command with hires flag for our high resolution fMRI data, but it has been in a constant status since yesterday. I copied the last few lines that are currently in my terminal. I had the same issue with another subject before, and I had to terminate the recon-all and run it without -hires. Could you please let me know how I can solve this issue?

?h.white does not exist
by Weber, Wade A 22 Feb '19

22 Feb '19

External Email - Use Caution Hi all, I'm trying to run -autorecon2 on 3 subjects (I already ran -autorecon1 on them with no errors.) and I'm getting an error after the -final_surfs part saying that lh.white does not exits (and it doesn't, I checked for it). I have run about 10 other subjects, and they all ran fine and contain ?h.white files. I saw 2 other strings in the archive with this same issue, but there was no resolution to them. This error just started happening, and I didn't change anything. Here's the command I've been using: recon-all -subjid <my subject #> -T2 <name of t2.nii file> -T2pial -autorecon2 Here's the error output: MRISread(/home/waw758/Desktop/secure/Mbemba/Mbemba_freesurfer_stuff/analysis_files/ANG_1034/surf/lh.white): could not open file I'm running freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c on a virtual machine running Red Hat Enterprise Linux Workstation 7.6 I've attached the recon-all.log file Thanks! ---- Wade A.

[All] postdoctoral position in PET imaging available at MGH / Martinos Center
by Bruce Fischl 22 Feb '19

22 Feb '19

Postdoctoral position in integrated PET/MRI at Massachusetts General Hospital / Harvard Medical School The Loggia and Hadjikhani Labs are inviting applications for a Post-Doctoral Research Fellow in the Department of Radiology at Massachusetts General Hospital (A.A. Martinos Center for Biomedical Imaging) and Harvard Medical School. The candidate will use state-of-the-art integrated PET/MRI scanners to image neuroinflammation in the central nervous systems of migraine patients, and the effect of nonpharmacological therapies. The candidate will collaborate with Dr. Julie Price and several other members of the Martinos Center. Requirements include a Ph.D. in Neuroscience, Physics, Chemistry, Engineering, or a related field, as well as good command of written and oral English. Experience with Positron Emission Tomography is preferred. Compensation is competitive and commensurate with experience. If interested, please email Marco Loggia (marco(a)nmr.mgh.harvard.edu) with your CV. _______________________________________________________ Marco L.

Templates used for eTIV computation in recon-all
by Ami Tsuchida 22 Feb '19

22 Feb '19

External Email - Use Caution Dear experts, We were comparing recon-all output of Freesurfer 5.3 and 6.0 in our database, and found that eTIV values can increase by up to 40% going from 5.3 to 6.0. However, closer inspection revealed that it was not due to the version per se, but how we call recon-all. We had computed one version with recon-all -all, and the other with recon-all -autorecon1, thinking that eTIV output from these two were identical. Some testing in two versions with two flags showed that in both versions, using -all flag automatically add --atlas 3T18yoSchwartzReactN32_as_orig in the talairach_avi command, while -autorecon1 does not. The talairach_avi.log indicates that the former set the target to 3T18yoSchwartzReactN32_as_orig, while the latter use the 711-2C_as_mni_average_305. My first question is, is this some kind of bug or is it intentional? We thought that the difference in the templates caused the change in the estimates, but it looks like that's not the only answer: We still get very different eTIV values from -autorecon1 option in FS5.3 and 6.0, even though the target images are the same. The results from -all option are more comparable. Here is the eTIV from one subject we tested: -FS5, autorecon1: 1318267 -FS6, autorecon1: 1561456 -FS5, -all: 1662005 -FS6, -all:1678336 Here I attached the shortened recon-all log files from two versions of Freesurfer, with with -all or -autorecon1, as well as eTIV output from the four variations we tested in one subject. Could you help us resolve why we get the varying estimates? Thank you!

Re: [Freesurfer] commends of GLM for volume

External Email - Use Caution Yes, one more question where can I get the example of mri glimfit for ROI analysis ---Original--- From: "Greve, Douglas N.,Ph.D."<DGREVE(a)mgh.harvard.edu> Date: Tue, Feb 19, 2019 22:47 PM To: "freesurfer(a)nmr.mgh.harvard.edu"<freesurfer(a)nmr.mgh.harvard.edu>; Subject: Re: [Freesurfer] commends of GLM for volume You can get the volumes of structures, eg, hipocampal volume, for each structure and subject using asegstats2table, then mri_glmfit can read in that table. But it is an ROI analysis, not a voxel-wise analysis. Is that what you want to do?

dt_recon registration check
by Daniel Davidson Callow 22 Feb '19

22 Feb '19

External Email - Use Caution Hello, I have run through dt_recon and want to use anatomically based segmentations (aseg) to create ROIs for the diffusion-weighted data using mri_vol2vol. I ran mri_vol2vol --mov $subj_dir/dtrecon/${subj}.${cond}./lowb.nii.gz --targ $subj_dir/diffusion_recons/${subj}.${cond}/mri/aparc+aseg.mgz --inv --interp nearest --o $subj_dir/dtrecon/${subj}.${cond}./aparc+aseg2diff.nii.gz --reg $subj_dir/dtrecon/${subj}.${cond}./register.dat --no-save-reg Which worked. I now want to quality check and make sure the ROIs I make from the aseg2diff segmentation is accurately aligned in diffusion space (such as making sure the hippocampal ROIs for aseg are actually going to overlay the hippocampal region of the diffusion data). My question is what is the best way to quality check for quality registration between the diffusion and anatomical data?

PETSurfer: Needs for gtmseg

External Email - Use Caution Dear FS's experts, In the perspective of correcting generated surfaces errors or defects, does the gtmseg command need corrected surfaces or could it be launch independently before having these corrected surfaces ? Best, Matthieu

Registering from subjects to a common volume
by Tim Schäfer 22 Feb '19

22 Feb '19

External Email - Use Caution Dear list, I would like to register volume data from several subjects to a common volume, e.g., the volume of the fsaverage subject. The volume data contains some marked voxels and is in the same space as the orig.mgz of the respective subject. I would like to find/see the positions of the voxels in a volume like $FREESURFER_HOME/subjects/fsaverage/mri/brain.mgz. This would require a non-linear, inter-subject registration I guess. How can I do this in FreeSurfer? Most likely I can somehow use mri_vol2vol to achieve this, but I don't see how. Is the talairach transform what I want? -- Tim

How to get gray matter tissue via freesurfer?
by 潘祖江 22 Feb '19

22 Feb '19

External Email - Use Caution Hi all, I have came across a problem. As we know, by using recon-all command we can get white matter segmentation, but what I need to use is gray matter segmentation, so what could I do to get ideal segmentation? Hope to get response from someone who concerns. Thanks. -- -------------------------------- 潘祖江 Zujiang Pan 清华大学计算机科学与技术 Department of Computer Science and Technology Tsinghua University, 100084 +86 15600487317
