FSL questions
by Yang, Weiqi 31 Jul '19

31 Jul '19

Dear FreeSurfers, I would like to use fsleyes for imaging. Does anybody know how to source it? And what fsl command I should use if I want to extract all ROIs in aparc+aseg file and get their uptake value from PET image? I know how to do it for a single ROI. I am just wondering if there is an easy way to extract data for all ROIs. Thanks, Weiqi

make_average_subject error

External Email - Use Caution Dear all, I have seen this error mentioned several times on the list but I have never seen a solution posted. It is claimed that there is a patch and a README that explains the patch at: https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.0-patch/ In this folder there are a bunch of files but there is no README so I am not sure what exactly I need to do. I tried replacing the files in my /usr/local/freesurfer/bin with those in this patch folder but the error remains. This error appears with all my data sets that I have tried. So it doesnt seem to be something specific to my data.

Help for Hippocampal Calculation
by Jiajun Luo 30 Jul '19

30 Jul '19

External Email - Use Caution Hi, Now I have T1 and T2 images (dcm files) and want to calculate the hippocampal volume. I find it takes ~20h to run recon-all -all and then ~40min to run -hippocampal-subfields-T1. However, I need to calculate the hippocampal volume for more than 1,000 individuals (which means it may take ~3 years to complete). Do you know how I can improve my efficiency? Thank you!

Re: [Freesurfer] mri_curvature_stats: -a parameter has no effect and errors (FACES_aroundVertex_reorder: packed / faces mismatch, and Segmentation fault)

Dear Rudolph, Thanks a lot for your reply! Do you know why does it fail on holes/edges? Does the algorithm require each triangle vertex to have 1-ring neighbours? Also, do you by chance know how to use the -a parameter correctly? I did not observe any difference nor in the results nor in runtime with a call like this: mris_curvature_stats -a 5 -f surface -m -o noisy_sphere_r10_a5.stats -G --signedPrincipals --writeCurvatureFiles noisy_sphere noisy_sphere_r10 Many thanks and best wishes Maria On 30.07.19 18:00, freesurfer-request(a)nmr.mgh.harvard.edu wrote: > Hi Maria -- > > If there are holes/edges in the surface `mris_curvature_stats` it will > fail. -- Maria Kalemanov, M.Sc.

Postdoctoral Research Associate Position Available
by Shashwath Meda 30 Jul '19

30 Jul '19

External Email - Use Caution *Please direct all submission materials and inquiries to Dr. Michal Assaf @ michal.assaf(a)hhchealth.org <michal.assaf(a)hhchealth.org>* *Postdoctoral Research Associate Position * The Olin Neuropsychiatry Research Center is seeking to fill a postdoctoral researcher/fellow position in the area of autism/cognitive neuroscience focusing on imaging data analysis. The fellow will join a lab conducting research using advanced neuroimaging methods (MRI, DTI, fMRI) in both healthy and psychiatric populations. The major focus will be developing and applying statistical analysis methods such as ICA and dynamic Functional Connectivity to neuroimaging data collected in an NIMH funded study, which examines brain function related to social cognition and emotion regulation in individuals with autism spectrum disorder. Applicants should have a Ph.D. in Psychology, Neuroscience, or related field. They should have an understanding of fMRI statistical methods and experimental design, and promising research experience. The ideal candidate will come from a doctoral program that has provided fMRI data analysis skills, solid theoretical understanding of cognitive neuroscience and psychology/psychiatry, and working knowledge of Linux, Matlab (programming experience preferred), and similar systems to conduct fMRI analyses, or to have an existing track record with fMRI analysis. In addition to opportunities to develop their own program of research compatible with the lab mission, the postdoctoral fellow will have access to several large archival neuroimaging datasets, training in sophisticated data analysis techniques (i.e., independent component analysis, multi-modal analysis, etc.), and access to the center’s data collection and analysis resources (e.g., fMRI, sMRI, DTI, EEG, genotyping, neuropsychological assessment). The fellowship is open for an initial two years, with an option to renew. The Olin Center is an established clinical neuroscience center at the Institute of Living/Hartford Hospital and is affiliated with Yale University with over 40 faculty, postdocs and research assistants. Our mission is to conduct cutting-edge clinical and cognitive neuroscience research that can ultimately translate to psychiatric care. The Olin Center is located on the grounds of the Institute of Living, providing access to thousands of psychiatric patients each year treated in numerous clinical programs. This is an exciting opportunity for a clinical or cognitive neuroscience postdoc looking to establish him/herself in the field through productivity, training in advanced analysis techniques, and access to ample scientific resources. If interested, please send a statement of scientific interests, accomplishments and relevant skills, a CV, and contact information for at least 3 academic references to Dr. Michal Assaf, Autism & Functional Mapping lab director, at michal.assaf(a)hhchealth.org

TRACULA incorporate topup instead of field map?
by Daniel Callow 30 Jul '19

30 Jul '19

External Email - Use Caution Hello, I have previously used field map correction for b0 inhomogeneities when running TRACULA, however my new data set has A>P and P>A encoding. I know that topup has been shown to perform slightly better than filed map correction. I wonder if it would be possible to manually edit the ($dob0) then # B0-inhomogeneity "correction" part of the code and run topup instead of epidewarp.fsl? I am trying to determine how feasible this is and was wondering if this had been tried by others? If not, does it make more sense to process the data with topup separately and then incorporate it into TRACULA? Thank you for any guidance you can provide, *Daniel Callow* *PhD Student, Neuroscience and Cognitive Science* Exercise for Brain Health Lab University of Maryland, College Park *ddcc2442(a)gmail.com <ddcc2442(a)gmail.com>* 443-254-6298

mgz files not being recreated following recon-all
by Charles Tyshkov 30 Jul '19

30 Jul '19

External Email - Use Caution Hello, After running recon-all, and attempting to run freesurfer (using the command "checksurfswmflair") the following error message appears for number of studies: Failed to load MRI /Volumes/MSdata/SAG_3D_BRAVO/MS2030181102/lesion/flair_on_T1.flirt.nii.gz It seems that gz lesion files are not being created/carried-over for these studies after being run through my script (other studies interestingly are opening up successfully using the same script). The successful studies seem to contain the zip file. Any thoughts as to why certain studies which contain nii.gz files are failing to recompress after being processed? Thanks, Charlie

OK -- looked again -- and I need to fix the in-line help obviously. Anyway, this works: mris_pmake --subject testSubject \ --hemi lh \ --surface pial \ --curv sulc \ --mpmOverlay euclidean \ --mpmProg pathFind \ --mpmArgs vertexStart:121981,vertexEnd:132633 (obviously use your <subject>) Try that and let me know.

mris_pmake issue
by Sebastian Strauss 30 Jul '19

30 Jul '19

External Email - Use Caution Dear Freesurfers, I am trying to calculate distances using mris_pmake with Freesurfer Version 6.0.0. When using the command line the following error appears: mris_pmake: unrecognized option '—surface0' In January the similar question (https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg60835.html) was ask but without any answers. Does anyone have the same problem btw any suggestions? Thank you! Best wishes Sebastian
