Re: [Freesurfer] Doubts in hippocampal subfields labeling
by Antonin Skoch 08 Jul '19

08 Jul '19

External Email - Use Caution Dear Eugenio, I have uploaded the subject as file hippocampal_subfields_labeling.tar.gz to your server surfer.nmr.mgh.harvard.edu. RAS coordinates of the unlabeled area are -31,-27,-9. Thank you in advance, Antonin Dear Antonin, It is difficult to see what’s going on in the images you sent. Would you mind uploading the subject, or at least sending us the image without the segmentation overlaid (and ideally, a sagittal view as well)? Cheers, /Eugenio-- Juan Eugenio Iglesias Senior research fellow CMIC (UCL), MGH (HMS) and CSAIL (MIT) http://www.jeiglesias.com From: <freesurfer-boun...(a)nmr.mgh.harvard.edu> on behalf of Antonin Skoch <a...(a)ikem.cz> Reply-To: Antonin Skoch <a...(a)ikem.cz>, Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> Date: Tuesday, 2 July 2019 at 21:43 To: "freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu> Subject: [Freesurfer] Doubts in hippocampal subfields labeling External Email - Use Caution Dear experts, I noticed that systematically in most of my subjects there is area in hippocampal region, labeled in aseg as hippocampus, but NOT labeled as hippocampus in hippocampal subfields segmentation (it has zero value there). See screenshots with norm.mgz overlaid by 1) aseg, 2) hippocampal subfields segmentation. According to T1 and T2 signal, it should neither be white matter and also probably not a ventricle/CSF. Neocortex is not located here. It has similar signal intensity as hippocampus, so I think that it should be hippocampus, but I am puzzled by hippocampal subfields segmentation results there. Why it is not labeled? Could you please help me to clarify this? My concern is to correctly label this area. I could upload the example subject if it is of any help. Regards, Antonin Skoch

recon-all error: Correcting defect
by Miguel Ángel Rivas Fernández 08 Jul '19

08 Jul '19

External Email - Use Caution I ran the recon-all in one subject and and this process was stopped in the topology correction. In particular during the "CORRECTING DEFECT 36 (vertices=19847, convex hull=5892, v0=94733)". I reviewed the lh.inflated.nofix and the lh.orig.nofix files in Freeview and I noticed that the this error would be located in the lh.inflated.nofix file. I am not completely sure but I suspect that this error may be due to the fact that there is a large amount of brain lesion and this would difficult the topology correction. How can I fix this problem? Thanks in advance. Best regards, -- *Miguel Ángel Rivas Fernández*

External Email - Use Caution Candidates are being considered for a post-doctoral associate position in the Anticipation, Cognition and Emotion lab ( www.ace.pitt.edu ) at the University of Pittsburgh (http://www.pitt.edu) to work with Dr. Anna Manelis and her team. A successful candidate will work on the NIMH funded research project that uses multimodal neuroimaging (fMRI, MRI, DTI and fNIRS) to understand the contribution of anticipatory processing to cognitive and emotional dysfunction in individuals with mood disorders. Pittsburgh is a vibrant community which promotes diversity and collaboration within its university and medical systems. Our lab works in conjunction with the University of Pittsburgh Medical Center to perform neuroimaging studies which will help us to better understand mood disorders, including major depressive disorder and bipolar disorders. *Required Qualification*s: we are seeking a highly motivated candidate with a PhD degree (or anticipated PhD degree) in psychology, cognitive neuroscience, computational neuroscience or a related discipline. A strong research background in the analysis and interpretation of neuroimaging data is required. A successful candidate will have excellent writing and communication skills. Candidates with a strong computational background are encouraged to apply. Experience with FSL, Freesurfer and E-prime is preferred. The ability to program in Shell, Matlab, Python and/or R is preferred. Experience with fNIRS, graph modeling and pattern classification analyses is a plus. While prior experience with clinical populations is not necessary, we expect candidates to be interested in neuroimaging research of working and episodic memory and/or anticipatory and emotional processing in individuals with mood disorders. *Responsibilities*: · Help to run fMRI/fNIRS experiments · Analyze fMRI, MRI, DTI and fNIRS neuroimaging data · Write manuscripts · Present findings from studies at conferences This is a full-time position that can be extended to 3 years. We are looking for someone to join our lab in Fall 2019 (with some flexibility). This position is funded by the NIMH and salary will vary based on experience. If you are interested in this position, please send a CV, research statement, preprints/reprints of papers, and the names and contact information for two references to *Anna Manelis (manelisa(a)upmc.edu <manelisa(a)upmc.edu>).*

Assigning voxels different intensity values
by Fotiadis, Panagiotis 07 Jul '19

07 Jul '19

Hello, I was wondering whether there is a way to assign a different intensity value on each voxel within a parcellation file (such as aseg.mgz). What I’m essentially trying to do is create a file (using the aseg.mgz file as a template) where each voxel represents a different ROI. I can think of a way to do that in Freeview for each individual voxel but I wasn’t sure whether there was a more efficient/automated way in either bash or matlab. Let me know if the above doesn’t make any sense, and thanks in advance! Best, Panos
