Running recon-all with FLAIR / MRISread(../surf/lh.white.preaparc): could not open file

21 Mar '17

Dear all, I'm trying to add FLAIR data to a subject. I did the first ("classic") recon-all on a platform so I get the following warnings: INFO: FreeSurfer build stamps do not match Subject Stamp: freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0 Current Stamp: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c INFO: current FREESURFER_HOME does not match that of previous processing.

I don't really know what information does "preaparc" contain. Thank you for your help. Best regards, Veronica veronica.munoz(a)creatis.insa-lyon.fr <mailto:veronica.munoz.rmz@gmail.com>

Hello I need separate grey and white volumes for the frontal and temporal lobes. I have values for grey volume from the following... mri_annotation2label --subject 01 --hemi lh --lobesStrict lobar_annotation mris_anatomical_stats on the lh.lobar_annotation.annot file to generate a text file.

Re: [Freesurfer] wm.mgz Edits Ignored With Current Dataset in FS 5.3/6 Cross and Long Streams
by Antonin Skoch 20 Mar '17

20 Mar '17

Dear David, did you use -uselongbasewmedits in your recon-all -long run? If this flag is not used, the wm edits are transfered to long from cross, not from the base. Regards, Antonin Skoch Andrew, thanks for your response. I am still not seeing the white matter edit performance that I am expecting, or that I have seen from using the cross stream on 5.3 in the past with a different dataset.I started with a new subject with two timepoints. I ran recon-all on both for the cross stream with no edits, and then ran the base. I edited the wm.mgz for the base, then ran “recon-all –autorecon2-wm –autorecon3 –base xx_base –tp xx_t1 –tp xx_t2”. I noticed the surfaces didn’t really change in the base, but I went ahead and ran the two long runs using “recon-all –all –long xx_tx xx_base” and although there are minor differences in the base and time point surfaces, the white matter edits I did on the base were largely ignored, and none of them were included in the time point long run wm.mgz files. I am tempted to try these same analyses using Linux (I am running this on OSX 10.11 currently), as I experienced a completely different response from the surface generation modules to my edits in the past when using Linux. I’m thinking this is a real long shot, but I cannot otherwise figure out why the software would be behaving so differently from my past experiences. Any thoughts? Thanks! Best, David P.

Rerun autorecon2-wm and autorecon3 for the base dir, then completely rerun the longitudinals. The long surfaces are initialized from the base surfaces, so this could be why your wm fixes seem to have no effect. You can find more info here: https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalEdits#CheatSheet<https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalEdits> If editing the base doesn't solve the problem, you can send me the commands you ran in order and I can look into this further. best, Andrew ________________________________ From: freesurfer-boun...(a)nmr.mgh.harvard.edu <freesurfer-boun...(a)nmr.mgh.harvard.edu> on behalf of David Semanek <seman...(a)nyspi.columbia.edu> Sent: Monday, March 13, 2017 11:55 AM To: Bruce Fischl; Freesurfer support list Subject: Re: [Freesurfer] wm.mgz Edits Ignored With Current Dataset in FS 5.3/6 Cross and Long Streams Thanks, I have uploaded the cross and long stream processing from one subject which requires numerous white matter edits to correct defects in the white matter surfaces; the file is on the ftp server as dsemanek.zip. Both of the cross subject folders, s02_t1 and s02_t2 have had edits done to both the brainmask as well as the wm files, and autorecon2-wm and autorecon-3 have been run on them, as well as the long folder for the first time point, s02_t1.long.s02_base. It was in working with the rerun results of s02_t1.long.s02_base that I noticed the white matter surfaces after being regenerated with the edited wm.mgz did not reflect any of the edits. The easiest way to see this is to load the wm.mgz with the white matter surfaces and scroll through the slices, there are numerous areas where the contours of the white matter surfaces do not follow the voxels of the wm.mgz volume, mostly near what should be identified as hyperintense gray matter. I’m fairly certain the white matter surfaces didn’t change at all after running autorecon2-wm with the wm.mgz edits. Thanks for taking a look at our data. Best, David P.

wm.mgz Edits Ignored With Current Dataset in FS 5.3/6 Cross and Long Streams
by David Semanek 20 Mar '17

20 Mar '17

Hello, I have worked quite a bit in the past with fs 5.3 on datasets which required a fair number of manual edits to the white matter volume in order to correct defects in the white matter surface. Typically, these edits take the form of removing voxels in the wm.mgz volume that have been incorrectly identified as white matter, usually near the pial surface caused by intensity artifacts resulting from motion. My experience in the past is that generating the white matter surface after edits to the wm.mgz volume will reliably change the geometry of the resulting surfaces. However, on my current dataset, 1.5T adolescent brains with pervasive motion artifacts that do not meet the threshold for unusable data, absolutely no intervention I have done on the wm.mgz volume has any impact at all on the generation of the white matter surfaces. I am really very puzzled by this. All of the files that result from wm.mgz reflect the edits, however the aseg does not. The resulting white matter surfaces always follow the aseg white matter definitions and never the wm.mgz edits. I feel as if there might be something I am missing but this protocol has reliably been used to do white matter edits in the past. I thought it may be an issue with fs 6 or the long stream, but I have tried the same edits in 5.3, 6, long and cross streams and nothing at all has worked. Does anyone have any suggestions, or perhaps a hint that I am overlooking something common? Thanks, David P.

Postdoctoral Position - Multimodal neuroimaging in dementia
by Heidi Foo 20 Mar '17

20 Mar '17

Postdoctoral research fellow positions are available in the Department of Neurology Research at the National Neuroscience Institute, Singapore. Our focus is to use neuroimaging techniques as a surrogate pathological marker to understand the underlying neurobiological basis of dementia especially in the preclinical stages. We are seeking highly motivated individuals who have extensive research experience in neuroimaging analyses (e.g. structural, diffusion, functional MRI) using FreeSurfer, Statistical Parametric Mapping, and FMRIB Software Library; and demonstrate academic excellence including publications in first-class journals and conferences. The postdoctoral candidate should have a Ph.D. (or equivalent) in Neuroscience, Computer Science, Applied Mathematics/Statistics, Electrical Engineering, Biomedical Engineering, or related fields. Good command of programming tools including Matlab, C++, Linux, and scripting are necessary to carry out the research work in this group. The candidate will support our efforts either in advancing neuroimaging analysis technologies or in neuroscience applications. The successful candidate will be part of a diverse group including neuroscientists, radiologists, psychologists, physicists, biostatistician, and computer scientists, and will build upon the group's extensive foundation on neuroimaging analysis. If interested, please email resume to Professor Nagaendran Kandiah (nagaendran.kandiah(a)singhealth.com.sg)
