External Email - Use Caution Hello, I just started with Freesurfer and got the following error during the call of the command recon-all If: missing file name I should say that other commands work well. I looked for the error and it seems that it is a change in the script. I install Freesurfer in my Mac and did not change anything during installation. Why do I have this error then? Thanks a lot for your support, Yacila

Question about register
by 薛倩雯 19 Sep '18

External Email - Use Caution Dear Freesurfer experts, I need to transform a bunch of MNI coordinates of fiber tracts to native space. I have already registered my subjects to cvs_avg35_inMNI152 using mri_cvs_register. How can I transform the MNI coordinates back into the native space? Thanks!Qianwen

postdoctoral Fellowship for Child Brain Connectome and Genetics
by Anqi Qiu 19 Sep '18

External Email - Use Caution Job description: Growing Up in Singapore Towards Healthy Outcomes (GUSTO) is the most comprehensive birth cohort study over the world. The GUSTO mothers were recruited during pregnancy between 2009 and 2010. We have followed the GUSTO family since then. The GUSTO study collects the unique data on cognitive functions, children behaviors, psychopathology, and brain imaging at multiple points from birth to 7 years of age. We aim to study whether mothers mood, diet, and family lifestyle since pregnancy affect 1) their babies cognitive and brain development; 2) psychopathology later in life. We also aim to examine the role of genetics in such maternal influences. We are looking for postdoctoral fellows who are interested in the GUSTO study. Requirements: 1. PHD in Cognitive Neuroscience, or Psychology, or Imaging Genetics; 2. Experience with MRI-based neuroimage techniques; 3. Knowledge in statistical analysis is necessary; 4. Good communication and writing skills in English language; 5. Knowledge in longitudinal analysis will be plus plus. If you are interested in the jobs listed above, please send your CV to Deans Chair, Associate Prof. Anqi QIU Department of Biomedical Engineering National University of Singapore Email: bieqa(a)nus.edu.sg Phone: +(65) 6516 7002

Re: [Freesurfer] Surface Area in Toddlers/Children
by Douglas Greve 18 Sep '18

18 Sep '18

The flag to preserve area is not being turned on there. You can try running mris_preproc separately for area and including the --jac flag. If that does not work, you can download version6 and just use it to run mris_preproc On 8/10/18 4:41 PM, Derek Sayre Andrews wrote: > > External Email - Use Caution > > Hi Douglas, > > Of course, please find attached a copy of the recon-all.log file. > > Best, Derek > > PS: Apologies for the direct email in order to get you the attachment > > cid:image001.png@01D430A0.A5153C80 > > *Derek Sayre Andrews, PhD* > > Postdoctoral Scholar > > Department of Psychiatry and Behavioral Sciences > > The M.I.N.D Institute > > University of California Davis > > > Telephone: +1 916 703 0360 > Email: dandrews(a)UCDavis.edu <mailto:dandrews@UCDavis.edu> > > *From: *<freesurfer-bounces(a)nmr.mgh.harvard.edu> on behalf of Douglas > Greve <dgreve(a)mgh.harvard.edu> > *Reply-To: *Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> > *Date: *Friday, August 10, 2018 at 11:12 AM > *To: *"freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu> > *Subject: *Re: [Freesurfer] Surface Area in Toddlers/Children > > Yes. -qcache actually calls mris_preproc.

T2pial correction options
by Adam Martersteck 18 Sep '18

18 Sep '18

External Email - Use Caution Hi Freesurfer team, We’re having some trouble with the T2pial option. We are currently getting the Martinos Center ABCD project Tisdall/van der Kouwe vNav MPRAGE and T2SPACE at 0.8mm^3, bandwidth matched for distortion. Linked below are 2 gifs were we have found areas we thought the T2 and –T2pial option would help differentiate brain from non-brain: https://goo.gl/dc9pjj https://goo.gl/AsCCbA I’ve read the discussion by Bruce, Matt, and Antonin about altering the final lh/rh mris_make_surface command with the T2. Has anyone found more optimal numbers for the nsigma_above and nsigma_below arguments? Is there anything else I could try to get this working better? Thanks! -Adam

mris_register problem
by Chris Adamson 18 Sep '18

18 Sep '18

External Email - Use Caution Freesurfer experts, I'm having an issue with projecting labels from an atlas to a subject. I have a static annot file on the atlas that I want to paint onto my subject. The pipeline I have performed is to mris_register my subject to the atlas and then mri_surf2surf on the annot file using the registered spherical surfaces. The labels, when painted, are incorrectly oriented. How can I debug the output of the registration to check if the registration is working? I assume the registration works in the 2D parameterised space, can I extract parameterised versions of the curvature maps at each iteration of the registration. The strange thing is that when I view the spherical surfaces in freeview with the overlaid curvature maps they look in alignment prior to registration, but using this unregistered sphere still puts the labels in an incorrect orientation. So it appears as if there is some rotation that is being done internally that isn't shown in freeview. Please advise, Chris.

How the resolution requirement was determined
by 조성현 18 Sep '18

18 Sep '18

External Email - Use Caution Hello Freesurfer developers and subscribers, I'm attempting to run brain segmentation with low resolution mri(thickness ~= 7mm) for EEG analysis. I know that this is very low resolution to get good quality results. However, I think the low quality result is not meaningless in specific cases. Therefore, I wonder if there is a tool to evaluate how low quality results are. In the 'freesurfer beginners guide', it says 'Thickness should not exceed 1.5mm'. How the resolution requirement was determined? How did you know that the input of 1mm ^ 3 resolution is sufficient requirement? If I use 2mm^3 resolution input, what kind of result will I get? It may be a little dumb, but I do not have an answer of this question. I would appreciate your reply. Thanks, Jo

Questions on multiple inputs
by limiyu 18 Sep '18

18 Sep '18

External Email - Use Caution Dear developers I have a question on how could I segment two registered MRI images and get only one segmentation result, by command recon-all ? In details, I have two MRI images which are T1-weighted and T2-weighted. They are the photos of one brain. How could I input both of them into Freesufer and output one segmentation result, which takes both of the input into consideration. I know that command "recon-all -all" could output the segmentation but do not know what to do when there are multiple inputs. Looking forward to your reply Thank you Mingyuan Liu
