bbregister --init-spm with Freesurfer 6.0
by Ajay Kurani 06 Apr '16

06 Apr '16

Hi Freesurfer Experts, I was running bbregister and came across an issue. I have used previous versions of bbregister (FS 5.3.0 with spm8) with the --init-spm at it worked perfectly for a specific subject. I recently installed FS dev 6.0 with SPM12b and ran bbregister --init-spm option with the same resting state scan, and it did not move at all. When looking at the terminal I saw that when matlab started up within bbregister, the command fs_spmreg was not found. I also installed spm8 and reran the subject with the same issue. When I changed the option to --init-fsl everything worked. I checked the matlab installation and everything looks fine, so I think the issue may be the fs_spmreg function not being found. I am not sure if there is an easy fix for this, but any help would be appreciated. Thanks, Ajay

Nonisotropic PSF in mri_gtmpvc
by Ian Kennedy 06 Apr '16

06 Apr '16

Hello, Is there a way to specify a nonisotropic PSF when using mri_gtmpvc? I have reason to believe there are differences between the axial and transverse resolutions of the PET scanner in my study and would like to incorporate them if possible. Thanks, Ian Kennedy

Data manager/programmer position
by Gregory Book 06 Apr '16

06 Apr '16

The Olin Neuropsychiatry Research Center is seeking a data manager/programmer to help maintain neuroimaging databases in support of multiple NIH funded projects. The Olin Center is a neuropsychiatric research center within Hartford Hospital’s Institute of Living campus. We house a 3T MRI, multiple EEG, TMS, and eye tracking systems, an internal database of nearly 13,000 MRI sessions, and a 400-core compute cluster. The primary responsibilities of the data manager will be to maintain internal and public imaging databases by performing the following tasks: remove personally identifiable information, perform uploads to NIH repositories, identify missing data, organize identifiers, support remote sites with data importing/uploading, and ensure data redundancy and backups. Additionally, the data manager may contribute to the development of the Neuroinformatics Database (http://github.com/gbook/nidb) using SQL, PHP, Perl, C++ and other programming languages for the purpose of making data management more efficient and robust. The data manager also will have the opportunity to participate in research projects and contribute to manuscripts. Bachelor’s degree in engineering, science, neuroscience, or psychology is required, Masters or higher is preferred. Candidate is expected to have experience in SQL programming and at least one programming language. Proficiency in multiple programming languages is highly desirable.

segmentation fault mri_convert Ubuntu 14.04 again
by Griffa Alessandra 06 Apr '16

06 Apr '16

Dear all, I get a segmentation fault when running mri_convert, FreeSurfer version 5.0.0 on a fresh Ubuntu 14.04 installation. In the past, and on a different machine, I could fix this problem by copying the Ubuntu_12.04 file libcrypt-2.*.so to the $FREESURFER_HOME/lib folder of the Ubuntu_14.04 machine (as suggested here: https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2014-September/04052…) Anyway, on my new Ubuntu_14.04 machine, this trick does not work anymore and I cannot run FreeSurfer 5.0.0. Can somebody help me please? Thank you very much! Regards, Alessandra Griffa

longitudinal pipeline surface error
by Mihaela Stefan 06 Apr '16

06 Apr '16

Dear FreeSurfers, We are doing a longitudinal analysis with three time points (MRI1, MRI2, MRI3). All the subjects were processed well except for one. The MRI3.long of that subject has very bad surfaces (see attachment - I am also attaching the log file). The cross, the template and the first two long runs were reconned well, though. We can't figure out why this third run is so bad. As a note, we processed all the cross runs on an Ubuntu machine but we ran the longitudinal pipeline on a computer cluster (both with freesurfer v5.3). We ran the long twice for that subject thinking that the pipeline crashed somehow the first time. However, the results were the same. Any help would be appreciated. Thanks! Mihaela

dt_recon image inputs -i flag
by Chiu, Bryan (PHTH) 05 Apr '16

05 Apr '16

Hi, I’m looking to do some DTI analysis with dt_recon. I have Philips acquired DTI images in par/rec. I ran dcm2nii and have retrieved the associated *bval, *bvec and *nii.gz files that come out. In the tutorial it mentions the -i flag requiring a dcm image. Is it possible to pass a *.nii.gz file ?
