need assistance to decode QDEC results
by vittal korann 17 Dec '20

17 Dec '20

External Email - Use Caution Dear FreeSurfer experts, I was running group interaction (for diagnosis and birthplace) in QDEC with gyrification as a dependent variable and age, gender as nuisance factors. In diagnosis, we have 2 groups: i) schizophrenic patients ii) healthy volunteers. Similarly, birthplace has 2 groups: i) urban ii) rural birth For the above-said design, I got reddish yellow color results in the display tab of Qdec. So, my query is that do results indicate that patients who were born in urban have a higher gyrification index than healthy volunteers who born in urban or something else? Do I sound correct in decoding the interaction results? If not please let me know the exact meaning of the results. Looking forward to hearing from you. Thanks, Vittal

Hippocampus left out in longitudinal study
by Albulena Shaqiri 17 Dec '20

17 Dec '20

External Email - Use Caution Dear all, I am new to freesurfer and this might be an evident question, if so, I am sorry. We have a longitudinal study with t0 and t1 scans. I followed the procedure and did the 3 steps. 1. Cross (with the following command: recon-all -subject 01_t0 -i /subjectfiles/t0/sanlm_13.nii -all -qcache -notal-check) 2. Base (recon-all -base 01_t0t1template -tp 01_t0 -tp 01_t1 -all) 3. Long (recon-all -long 01_t0 01_t0t1template -all) The problem is once I am inspecting the data, I see that the hippocampus is left out in all the cases (4 different subjects are attached in the screen captures).I used this command: freeview -v 01_t0/mri/norm.mgz \ -f 01_t0/surf/lh.pial:edgecolor=red \ 01_t0/surf/rh.pial:edgecolor=red \ 01_t0/surf/lh.white:edgecolor=blue \ 01_t0/surf/rh.white:edgecolor=blue) Also, you should know that we used for T1 MP2RAGE instead of MPRAGE. Is there anything I can do without having to re-do all the corrections by hand point by point and without having to restart over all my data pre-processing? I have to specify that we are interested in the hippocampus, so this is a major point in our study. Thanks in advance for your help, Alba [image: Screen Shot 2020-12-09 at 15.45.30.png] [image: Screen Shot 2020-12-09 at 15.45.38.png] [image: Screen Shot 2020-12-09 at 15.45.45.png] [image: Screen Shot 2020-12-09 at 15.45.55.png]

MP2RAGE pial surface edit error
by Elisa Rehbein 17 Dec '20

17 Dec '20

External Email - Use Caution Dear Freesurfer experts, we are currently running recon-all for our MP2RAGE images, using Freesurfer 7. However, when trying to edit pial surface errors and re-running (recon-all -autorecon-pial -subjid) it does not adjust the surface for some participants and leaves a black space (see picture attached). For denoising the salt and pepper noise in the background we used the script provided by (Marcques et al. 2010). We are very confused as to why this may be happening for some subjects, as the background noise seems to be removed equally for all subjects. Do you maybe have suggestions for us on how to solve this problem? Many thanks in advance! Kind regards, Elisa

1 PostDoc and 1 PhD Position available at University Hospital Cologne - Germany {Disarmed}
by Merle Hönig 17 Dec '20

17 Dec '20

External Email - Use Caution The Multimodal Neuroimaging Group at the University Hospital Cologne (visit us on https://secure-web.cisco.com/19Wxvgr1d6Wzl6rJWybWxBosnfgQu9HN-Ju0G9UAxz0P3Y…) currently looks for two highly motivated and qualified scientists (1 PostDoc and 1 PhD position) with a background in neuroscience or related fields. The positions are available as early as possible. The candidates will mainly work on a project focusing on the impact of striatal dopamine loss on vigor, planning, and motivation of movements as well as the role of motor reserve in patients with prodromal and clinical Parkinson’s disease. In this project, we will apply a unique combination of behavioral and computational phenotyping and state-of-the-art molecular, functional, and structural neuroimaging technologies (e.g. 7T MRI, dopamine transporter imaging). The successful candidates will be involved in the preparation and conduct of the study and the analysis and publication of newly acquired and already existing datasets. The positions provide the excellent opportunity to work in an interdisciplinary environment as part of the recently awarded Collaborative Research Center “SFB 1451: Key mechanisms of motor control in health and disease” with an integrated Research Training Group. For more details please see the official advertisement or attachment: https://secure-web.cisco.com/1lXwa1UK7Y5Mh6M-4mWn2QFc9BCdVXUsLlQ_KkbRm--4eB… We are looking forward to your application!

Re: [Freesurfer] Recon-all error: MatrixMultiply: m1 is null!
by Hoopes, Andrew 16 Dec '20

Hi Nárlon, Unfortunately, this is a known bug with parallel processing in FS 7.1.1. A fix will make it into the next v7 patch. As you mentioned, this error occurs at random, so in the meantime, you can mitigate this by either: - Rerunning recons until they don’t fail (not recommended) - Rerunning these failing recons without the parallel flag enabled - Patching your version of recon-all by commenting out or removing the following (line 4217) from $FREESURFER_HOME/bin/recon-all: if($OMP_NUM_THREADS > 1) set cmd = ($cmd --parallel) Hope that helps, Andrew From: <freesurfer-bounces(a)nmr.mgh.harvard.edu> on behalf of "Boa Sorte Silva, Narlon" <narlon.silva(a)ubc.ca> Reply-To: FS Help <freesurfer(a)nmr.mgh.harvard.edu> Date: Monday, December 14, 2020 at 7:31 PM To: FS Help <freesurfer(a)nmr.mgh.harvard.edu> Subject: [Freesurfer] Recon-all error: MatrixMultiply: m1 is null!

Multiple Frames Error
by Hsieh, Stephanie 14 Dec '20

14 Dec '20

Hi FreeSurfer Developers, I am trying to process a few MPRAGE sequences (different sessions), so I can edit the scans. And I am having trouble reconning the .mgz files. I have looked into why my job terminated early and I have attached the message below. The error states that ‘input(s) cannot have multiple frames’. And I then looked into the mri_info, which I have also attached below, and based off of some similar questions I found in the archive, my dimensions seem to be incorrect for freesurfer to process. My dimensions are 240 x 256 x 176 x 2, and I believe they should be 240 x 256 x 176 in order for it to work. How do I go about fixing my dimensions? Does it have to do with how I unpacked the DICOMS? I have not run into this issue before so I would love to learn what caused this error. Thanks in advance, Stephanie Early termination error: Subject Stamp: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c Current Stamp: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c INFO: SUBJECTS_DIR is /autofs/cluster/brutha/FS6 Actual FREESURFER_HOME /autofs/cluster/freesurfer/centos6_x86_64/stable6_0_0 Linux compute-0-85.nmr.mgh.harvard.edu<http://compute-0-85.nmr.mgh.harvard.edu/>3.10.0-1160.6.1.el7.x86_64 #1 SMP Tue Nov 17 13:59:11 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux '/autofs/cluster/freesurfer/centos6_x86_64/stable6_0_0/bin/recon-all' -> '/autofs/cluster/brutha/FS6/SCD_021_BL/scripts/recon-all.local-copy' /autofs/cluster/brutha/FS6/SCD_021_BL mri_convert /autofs/cluster/brutha/FS6/SCD_021_BL-1.mgz /autofs/cluster/brutha/FS6/SCD_021_BL/mri/orig/001.mgz mri_convert.bin /autofs/cluster/brutha/FS6/SCD_021_BL-1.mgz /autofs/cluster/brutha/FS6/SCD_021_BL/mri/orig/001.mgz $Id: mri_convert.c,v 1.226 2016/02/26 16:15:24 mreuter Exp $ reading from /autofs/cluster/brutha/FS6/SCD_021_BL-1.mgz...
