Could not read curvature from curv
by Anneliis Sartin-tarm 31 May '18

31 May '18

External Email - Use Caution Hello all, I noticed that after I ran recon-all -autorecon2-wm -autorecon3 to incorporate manual edits from a white matter surface inspection, many abnormal hard failures occurred. First, upon checking to see if my subject successfully ran through recon-all via tail scripts/recon-all.log, I received neither "finished without errors" or "finished with errors," but instead, this: SURFACES 3 flags 0 (0) use curv 0 no sulc 0 no rigid align 0 mris->nsize 2 mris->hemisphere 1 randomSeed 1234 singular matrix in quadratic form I then checked the subject's status via tail scripts/recon-all-status.log and received this: #@# Smooth2 lh Tue May 22 16:41:17 CDT 2018 #@# Smooth2 rh Tue May 22 16:41:24 CDT 2018 #@# Inflation2 lh Tue May 22 16:41:30 CDT 2018 #@# Inflation2 rh Tue May 22 16:42:10 CDT 2018 #@# Curv .H and .K lh Tue May 22 16:42:56 CDT 2018 #@# Curv .H and .K rh Tue May 22 16:44:22 CDT 2018 #@# Curvature Stats lh Tue May 22 16:45:40 CDT 2018 #@# Curvature Stats rh Tue May 22 16:45:43 CDT 2018 #@# Sphere lh Tue May 22 16:45:47 CDT 2018 #@# Sphere rh Tue May 22 17:20:21 CDT 2018 I then attempted to view the subject in Freeview, which only loaded the surface edges and not the inflated 3-D surface, and this message appeared in my terminal -- which is the same message in the subject's error.log folder: MRISreadNewCurvature: incompatible vertex number in file /Volumes/Vol2/cisler/freesurfer/ testing/annewuwu/surf/lh.curv No such file or directory could not read curvature from curv No such file or directory mpatible vertex number in file /Volumes/Vol2/cisler/freesurfer/testing/annewuwu/surf/lh.curv MRISreadNewCurvature: incompatible vertex number in file /Volumes/Vol2/cisler/freesurfer/ testing/annewuwu/surf/lh.curv No such file or directory could not read curvature from curv No such file or directory mpatible vertex number in file /Volumes/Vol2/cisler/freesurfer/testing/annewuwu/surf/lh.curv MRISreadNewCurvature: incompatible vertex number in file /Volumes/Vol2/cisler/freesurfer/ testing/annewuwu/surf/rh.curv No such file or directory could not read curvature from curv No such file or directory mpatible vertex number in file /Volumes/Vol2/cisler/freesurfer/testing/annewuwu/surf/rh.curv MRISreadNewCurvature: incompatible vertex number in file /Volumes/Vol2/cisler/freesurfer/ testing/annewuwu/surf/rh.curv No such file or directory could not read curvature from curv No such file or directory mpatible vertex number in file /Volumes/Vol2/cisler/freesurfer/testing/annewuwu/surf/rh.curv It looks like I most likely have to rerun the subject through recon-all, but does anybody have any tips to prevent this from happening again?

Regional comparisons between cortical thickness and white matter hyperintensity
by Fotiadis, Panagiotis 31 May '18

31 May '18

Hello, I'm interested in looking into the association of cortical thickness and white matter hyperintensity from a regional perspective. Specifically, I would like to create a figure that depicts in which ROIs does cortical thinning correlate significantly with increased white matter hyperintensity volume of the underlying white matter (not just the overall white matter hyperintensity). I have created binary masks of the white matter hyperintensity burden on each patient, and I was planning on projecting them into each respective cortex. However, I didn't know what the next step should be. I was thinking about the group analysis pipeline but didn't know whether it was applicable, as I don't want to just adjust for global white matter hyperintensity volume. Thanks in advance for any help! Best, Panos Panagiotis Fotiadis Senior Imaging Research Technologist J. P. Kistler Stroke Research Center, Department of Neurology Massachusetts General Hospital, Boston, MA T: (617) 643-3869

brainmask volume disappearing in certain planes in freeview
by Rachel Smallwood Shoukry 31 May '18

31 May '18

External Email - Use Caution Hello FreeSurfer developers, I'm having an odd problem using freeview. When I open a set of volumes (wm and brainmask) and surfaces (both pial and white), everything seems to work fine. However, when I turn off the volumes to look at the 3D view and then turn them back on when switching back to 2D, the situation in Screenshot1 happens. The brainmask volume disappears in the coronal and axial planes but is still there in the sagittal. Also, it looks like a coordinate appears in large text written backwards superimposed over the surface outlines (mirrored, not just in reverse order), but it's not the coordinate from the current slice. For instance, this coronal slice says R 97.66 and the axial slice says R 147.65. If I zoom in or out, the numbers get larger and smaller. The white matter volume is not affected. Everything works normally if I keep the volumes for viewing 3D rendering. I have a similar thing happen when adding control points (it first happened when creating a new set, but if I load an existing set it happens also). The image is fine until I get to a specific coronal slice (usually just a few slices away from where I put the first control point), then the brainmask volume disappears in the coronal view but is still there in sagittal and axial. This time the displayed number is A 58.73 (mirrored), which is actually the label on the exact slice where brainmask disappears for this subject, but this number does change sometimes when scrolling through slices, but not on most slices and it doesn't change to match the current label. If I close and re-open freeview with the same set of volumes and surfaces, they come up the way they should and remain as they should unless I turn off the volumes while looking at the 3D rendering or open the control point file again. This has happened for multiple subjects/sets of files, and no messages appear in the terminal when this happens. I'm using a Linux with CentOS 6.9. Any idea what could be causing this and/or how to fix it? Thanks! Rachel

Re: [Freesurfer] multi-band slice timing correction
by Douglas Greve 31 May '18

31 May '18

if you are using version 6, then you can just specify the number of slice groups (-ngroups) when running preproc-sess. doug ps. Please post to the FS list.

Is there a way for me to use preproc-sess and include a slice timing file there somewhere? I guess I could do everything using separate commands, e.g., use "stc-sess" for slice timing correction with the slice timing file by including "-sdf slicedelayfile", then do "mc-sess”. > > Any advice you have would be greatly appreciated.

FW: Number of iterations with --cache flag
by Backhausen, Lea 31 May '18

31 May '18

External Email - Use Caution Hey Doug, thanks for the suggestions! I have some follow-up questions, also regarding your recently published paper about false positive rates (https://www.sciencedirect.com/science/article/pii/S1053811917310960) 1) What will the difference be between 1000 and 10,000 iterations? I read in the tutorial that >5000 iterations are recommended? 2) In your paper you write that permutation requires that data is exchangeable across subjects and that age effects may be a problem. In our study we want to compare adolescent patients with ADHD and conduct disorder with typically developing adolescents. In this context, data would not be exchangeable across subjects, right? Could we still use permutation? 3) When using the CFT thresholds with Monte Carlo simulation you recommend in your paper, do you still only report clusters with CWP<.05 or is the CWP less important when using stricter thresholds? 4) Which surface area do you use in your paper? White or pial? Is one "better" to use than the other? Thank you so much for your input!

midbrain mask in standard-space?
by djpeters＠u.washington.edu 30 May '18

30 May '18

External Email - Use Caution Hi Freesurfer email list, I'm trying to get the midbrain mask from the brainstem segmentation pipeline into standard space, for use in analyzing some data in other modalities. I have labeled T1s in individual-space (it's a longitudinal pipeline). Does the brainstem atlas already exist somewhere in MNI-space as a mask? If so, where could I find it? I've found the ROI mesh data, but I don't know how to convert that into a voxel mask. Thanks so much, -Dan Peterson

Missing register.dof6.lta.file after FAST Preprocessing
by Wang, Zhuonan 30 May '18

30 May '18

Hi Team, I am using FsFastTutorialV6.0<http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastTutorialV6.0> to run FAST Preprocessing. The Functional-Anatomical Cross-modal Registration should have 6 files but I lost the register.dof6.lta. I try to run the command register-sess -s $subj -per-run -fsd bold but there was still missing register.dof6.lta. file. How can I do for the next step? Thanks you! Zhuonan

EEG and MEG Source Reconstruction with FieldTrip @OHBM2018
by Maria Carla Piastra 30 May '18

30 May '18

External Email - Use Caution Dear all, on 17 June 2018 we will host a workshop at the OHBM2018 conference <https://www.humanbrainmapping.org/i4a/pages/index.cfm?pageID=3821> . The course is aimed at researchers who want to learn how to do MEG and/or EEG**source reconstruction. We expect that you know the basics of MATLAB and that you already have experience with MEG/EEG preprocessing and analysis. In this intense one-day workshop we will explain state-of-the-art MEG and EEG source reconstruction methods. The workshop will consist of a number of lectures, followed by hands-on sessions in which you will be tutored through the complete analysis of a MEG, EEG and MRI data set using the FieldTrip toolbox. As the focus is on source reconstruction, topics that will NOT be covered in great detail are segmenting, artifact handling, averaging, frequency and time-frequency analysis, statistics. For the hands-on sessions you should bring a laptop with MATLAB installed. More information about the program can be found at the OHBM website <https://www.humanbrainmapping.org/files/2018/ED/EEG%20and%20MEG%281%29.pdf> or on the FieldTrip website. <http://www.fieldtriptoolbox.org/workshop/ohbm2018> Best regards, Maria Carla Piastra1 , Sophie Schrader1 and Simon Homölle2 * * 1Institute for Biomagnetism and Biosignalanalysis, University of Münster, Münster, Germany. 2 Donders Institute for Brain, Cognition and Behaviour, Radboud University, Nijmegen, The Netherlands.
