Postdoctoral Fellowship in Neurobiological Bases of Reading (MRI and DTI)
by Clint Johns 19 Jun '18

19 Jun '18

External Email - Use Caution Dear colleagues, POSTDOCTORAL FELLOWSHIP IN NEUROIMAGING (MRI and DTI) The LandiLab (PI: Nicole Landi, PhD https://landi.lab.uconn.edu/) at Haskins Laboratories https://haskinslabs.org/ (which is closely affiliated with Yale University and the University of Connecticut) is seeking to hire a full-time postdoctoral research fellow. This postdoc will join a project investigating the neurobiological basis (brain structure, genetics) of reading. The successful applicant will be responsible for conducting and interpreting analyses of neuroimaging data (structural and diffusion imaging data). This position is part of a multi-site project (Haskins Laboratories, University of Houston, Baylor College of Medicine) that is aggregating and analyzing neuroimaging and genotyping data from multiple locations to explore gene-brain-behavior relationships. Applicants must have a background conducting research using MRI. The ideal candidate will also have experience with diffusion weighted imaging (DWI) and experience with advanced statistical analysis of imaging data (e.g. imaging-genetic analyses, Bayesian methods, machine learning). For details regarding required qualifications and application procedure, please visit: https://haskinslabs.org/postdoctoral-fellowship-neuroimaging-mri-and-dti Thank you! Clinton L. Johns, Ph.D. Research Scientist, Haskins Laboratories 300 George Street New Haven CT 06511 speech: 203-865-6163 x240 fax: 203-865-8963 net: johns(a)haskins.yale.edu

Huge triangles in average template
by Dr. Konstantin Weise 19 Jun '18

19 Jun '18

External Email - Use Caution Dear Freesurfer team, in the left hemisphere of the average template in Brodmann area 4 (M1), there are some huge triangles, which make data analysis hard. I attached an example image to it. I was able to complete the whole pipeline, i.e. generating the template from some subjects and mapping the data to it using the following commands: > make_average_subject --out avg_template --subjects ... > mri_surf2surf --srcsubject ... --trgsubject ... --srcsurfval ... --trgsurfval ... --hemi lh --src_type curv --trg_type curv I already saw the bug in the shipped version of the freesurfer average template. Is there any way to solve this problem? Thank you very much for your assistance and best regards! Konstantin ----------------------------------------------------------- Dr.-Ing.

Re: [Freesurfer] [Request of response] Fwd: Error during QDEC

Those are the qdec tables, not the fsgd file. Look in the qdec output folder for a file called y.fsgd.

Can freesurfer work well to T1 images without TR/TE/TI and flip angle information？
by He Chen 18 Jun '18

18 Jun '18

External Email - Use Caution Hi freesurfer experts, The recon-all command was conducted to my data by: recon-all -all -s sub1 -i anat.nii . But freesurfer seems to not be able to read the TR/TE/TI and flip angle information in the .nii file. Or there is no information about TR/TE/TI or flip angle stored in the .nii file. Although the terminal told me recon-all finished without errors, I think there still may be some implicit and fatal errors. I want to know whether all the processing steps in 'recon-all -all' command can work appropriately without TR/TE/TI and flip angle information? See the recon-all.log file: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ... reading from /media/emily/DATA_Storage/test_freeview/sub1/mri/rawavg.mgz... TR=0.00, TE=0.00, TI=0.00, flip angle=0.00 ... recon-all -s sub1 finished without error at Fri Jun 15 04:36:11 CST 2018 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Thank you! He

I read in the tutorial that >5000 are recommended? > This has to do with the precision of the cluster p-value Since you are doing a simulation, the p-value is subject to sampling error. If you look in the output file, you will see that I give 95% confidence intervals for the p-value, so as long as the high range is less than .05, then it should be ok.

mri_glmfit ERROR no voxels found
by Marine Boudot de la Motte 18 Jun '18

18 Jun '18

External Email - Use Caution Hello FreeSurfer Developers, I'm attempting to do a Surface-based analysis on Freesurfer while projecting MTR MRI sequences. I have followed all the steps explained in the group analysis tutorials, and the mri_preproc seems to have ran correctly but once the mri_glmfit is launched i get the following error : Computing normalized matrix Normalized matrix condition is 38.1502 Matrix condition is 1.78431e+12 Found 149926 points in label. Pruning voxels by thr: 1.175494e-38 Found 0 voxels in mask ERROR: no voxels found in the mask make sure at least one voxel has a non-zero value for each input I've searched the list but didn't find an answer. Does anyone have any clue on how to solve this problem ? Thank you very much for your help, Marine

Re: [Freesurfer] Longitudinal analysis of multiple scanner acquisitions

External Email - Use Caution Hello Freesurfer Team, Sorry to bother you guys again, any word on what you think is the best approach going forward here? Best, Kody Zalewski ________________________________ From: zalewk Sent: Thursday, June 7, 2018 10:39 AM To: freesurfer(a)nmr.mgh.harvard.edu Subject: Longitudinal analysis of multiple scanner acquisitions Good afternoon Freesurfer team, I want to run the longitudinal pipeline on multiple groups of subjects, the problem is we are at the mercy of the scanners available to us at the various time-points. We have two different Siemens 1.5 scanners (same type of scanner, there was an effort made to match them) at time point 1 and 2 with a Phillips 3T at time point 3. Is it worth the time to attempt a longitudinal analysis on this cohort? Best, Kody Zalewski

Running qcache on old FS data
by Jamie Hanson 18 Jun '18

18 Jun '18

External Email - Use Caution Hello all, I was trying to run qcache on some previously processed Freesurfer data from a colleague, but ran into some issues with missing files and wondered how best to proceed. Details: -The data was processed with (Freesurfer) v4.5.0 and I would ideally like to not reprocess it with a newer version (to keep in concordance with past published work, and also it's a large number of subjects, n=800+). -The qcache flag was not used with the data previously (to my knowledge), so I was attempting to run this command: recon-all -s $subj -qcache -When I try that command, I get an error regarding a missing lh.white.K file. I've uploaded the log file here: https://www.dropbox.com/s/94mnsy7wrps5ce2/recon-all.log?dl=0 I wondered if it was possible to complete qcache with the data as is? I searched on the list previously and saw one or two other folks had run into this issues; I, however, didn't see a final solution to things. Any thoughts or suggestions are greatly appreciated! Thanks much! Best, Jamie. -- Jamie Hanson Assistant Professor, Psychology Research Scientist, Learning Research and Development Center University of Pittsburgh Personal website: jamiehanson.org

Recon-all exited with errors
by Ryan Flores 18 Jun '18

18 Jun '18

External Email - Use Caution Dear FS developers, I tried running recon-all using the -parallel flag over the weekend, but to my surprise they all exited with errors. I’m hoping the problem is something subtle, but I’m having trouble understanding the error log (please see attached). Can someone point out the issue? Thank you for your help. Best, Ryan -- Ryan Flores Clinical Research Coordinator

Can freesurfer do SC (superior colliculus) segmentation?
by He Chen 17 Jun '18

17 Jun '18

External Email - Use Caution Hi all, I need ROIs of SC(Superior Colliculus). Can freesurfer distinguish it from other brainstem structures in segmentation? I also need to see responses of distinct layers of SC. Can freesurfer do layers segmentation according to the distance between each voxel and SC surface layer? That is, I need ROIs of different depth in the SC. The depth should be calculated by the distance from the voxel to SC surface. How to modify the 'recon-all -all' code if I just need the segmentation function mentioned above? Please forgive the ignorance of a freesurfer beginner. Thank you in advance! Chen He
