Dear experts, I have analysed T1 data using Freesurfer. Now we have created atlas, template & tissue probability map using different methods and softwares. I need your help to use template in freesufer, so that we can compare with default template and our template. Please help me to put these images in appropriate folders in Freesurfer. Thank you RB

PROGRAMMER/ANALYST II G. OPPENHEIMER CENTER FOR NEUROBIOLOGY OF STRESS AND RESILIENCE UNIVERSITY OF CALIFORNIA, LOS ANGELES Background: The G. Oppenheimer Center for Neurobiology of Stress and Resilience (Mayer Lab) in the Vatche and Tamar Manoukian Division of Digestive Diseases, David Geffen School of Medicine at the University of California, Los Angeles is seeking a full time Programmer/Analyst for a multi-site funded translational research group studying brain-gut microbiome interactions in obesity and functional pain disorders including irritable bowel syndrome (IBS), chronic pelvic pain and interstitial cystitis, and vulvodynia. This position will use multimodal MRI sequences to study structural and functional circuit dynamics cross sectionally and longitudinally within a dimensional systems biology approach. The programmer’s main responsibilities include: programming and optimizing automated data quality control, preprocessing, computational, and analyses pipelines for large scale multimodal brain imaging and biological data. The candidate should have a strong programming background in one or more of the following areas: bioengineering engineering, computer science, statistics, physics, and/or neuroscience. There will be opportunities to address basic and pathophysiological systems questions, in addition to work in an environment that emphasizes translational and clinical research skills (e.g. target discovery, individualized treatment development and biomarker/predictor development). The G. Oppenheimer Center of Neurobiology of Stress and resilience is a dynamic multidisciplinary group directed by Emeran A. Mayer, MD, PhD conducting clinical, translational and basic neuroscience research. You will work directly with him and an array of principle investigators, collaborators and co-investigators. Duties and Responsibilities: The Scientific Programmer and Data Analyst responsibilities will include, but are not limited to: 1. Maintain and continue to develop a full-stack application for managing and analyzing neuroimaging data <>. The back-end consists of ~9000 lines of Matlab code for processing data and over 10000 lines of MySQL stored procedures and standard SQL for triggers, views, etc. The front-end consists of ~10000 lines of Javascript/JQuery and PHP code that allows for data entry and reporting. This application is in production and stable. 2. Programming and optimizing automated data quality control, preprocessing, computational and analyses pipelines for large-scale multimodal brain imaging, including resting‐state and task-based fMRI, DTI and volumetric data. 3. Implement and support statistical analyses and scripts for biological (e.g. microbiome, genetic, etc.), behavioral, clinical and neuroscience data. This will include performing mathematical calculations/statistical analyses needed for scientific research 4. Implementation of iCloud processing and analyses pipelines such as the Human Connectome Project. 5. Implementation of data visualization programs on MRI and biological data 6. Process and analyze fMRI data: 1st level analysis 7.

fast_selxavg3.m error/analysis.info file

Hello FreeSurfer experts, I am getting this strange error when running selxavg3-sess. (in selxavg3 command I am calling the analysis file with: -a rtopyTR2.rh) When the system enters fast_selxavg3, it cannot read analysis.info, thus produces the following output: #@# Sess05 ############################### /home/vm01/local/freesurfer/Project_bold/Sess05 ------------------------- $Id: fast_selxavg3b.m,v 1.4 2016/05/04 22:16:47 greve Exp $ ------------------------- outtop = /home/vm01/local/freesurfer/Project_bold Extension format = nii.gz ERROR: could not open rtopyTR2.rh/analysis.info else else echo "------------------------------------------" | tee -a $LF echo ------------------------------------------ tee -a /home/vm01/local/freesurfer/Project_bold/log/selxavg3-sess-bold-rtopyTR2.rh-180130082919.log ------------------------------------------ rm $MLF rm /tmp/selxavg3-sess-10173.m if ( ! -e $okfile ) then if ( ! -e /tmp/selxavg3-sess-10173.ok ) then echo "ERROR: fast_selxavg3() failed\n" ; echo ERROR: fast_selxavg3() failed\n ERROR: fast_selxavg3() failed\n exit 1 ; exit 1 The analysis folder it is referring to( rtopyTR2.rh) is in the directory from which I am calling selxavg3-sess. It has the analysis.info file in which doesn't have any restrictions. To troubleshoot, I moved the folder to inside the session's functional directory and inside the session folder and these didn't create any changes. I looked at the script and tried to debug there but didn't give any results. It gave a similar error when trying to open the config file of contrast in mkcontrast-sess. (I also don't have root access)Any help is appreciated! Best, Idil

FSFAST

Hello, I have several nifti files. I have preprocessed some of them before. I used this command: preproc-sess -s sess01 -fsd bold -stc odd -surface self lhrh -mni305 -fwhm 5 -per-session -force The output files contained fmc.odd.sm5.self.lh.nii.gz, fmc.odd.sm5.self.rh.nii.gz, fmc.odd.sm5.mni305.2mm.nii.gz, and *fmc.odd.sm5.nii.gz*. Which this last one (fmc.odd.sm5.nii.gz) was the file that I needed for my further analyses. However, when I run the same command on another nifti file which was obtained from the same scanner and the same session, the output doesn't have the fmc.odd.sm5.nii.gz. I ran it several times but it never gave me that file. Also, it doesn't give me any errors. I appreciate any help. Ash
