Re: [Freesurfer] mri_convert doubles file size when changing TR header information
by Douglas Greve 02 Oct '15

02 Oct '15

It is probably changing the data type from short to float. Try adding -odt short --no_scale 1 You can also look at the data type with mri_info --type file.nii On 10/1/15 10:52 AM, Shaun Patel wrote: > I noticed after running slice-time correction with SPM, the resulting Nifti files do not have TR information in the header. This breaks the Freesurfer pipeline. To get around this, I attempted to use the mir_convert function with the “tr” flag to set the TR. However, in doing so, I noticed that the resulting nifti file doubles in size. I used the following command: mri_convert f.nii f.nii -tr 2000, to set the TR to 2s.

] dt_recon
by Alshikho, Mohamad J. 02 Oct '15

02 Oct '15

Hi Doug, Thank you very much for your answers! Kindly I have one more question: At the end of DTI analysis using the tool “dt_recon” we will have “ stats” file including the FA value for every segment and parcellate in the brain. Depending on this output can we use the term “ DTI morphometry” to describe the analysis?

We are trying to move to the LTA as it is a much better format for these things. 2. How can I generate the file “ register.lta”? Use lta_convert, something like lta_convert --inreg register.dat --outlta register.lta --src lowb.nii.gz --trg $SUBJECTS_DIR/$subject/mri/orig.mgz 3. Can I feed the file “ register.dat” instead of the file “ register.lta” into the command “mri_vol2vol “ (in order to move the ‘’fa.nii” to anatomical space). If so which flag I should use instead of the flag “--lta” in the command mri_vol2vol? Yes, pass it with --reg flag.

Group Analysis

White Matter Edits vs. Control Points, & third party software
by Julio Alberto González Torre 02 Oct '15

02 Oct '15

I have some questions about how to manually correct the white matter regions . It's the same manually edit the volume "brainmask.mgz" and use control points? Would I get the same result? My intention is not to use control points, but directly replace the voxels that have not been classified as white matter with the value 110. Is it right to do this? My second question is: Is it possible to edit the volumes with a third party program? My intention here is to turn the volume "brainmask.mgz" to " brainmask.nii" using "mri_convert" command. Then edit the values of the voxels manually with a third party software or painting tool, and finally, turn the volume back to "brainmask.mgz", replace the file in their respective directory, and finally execute "-autorecon2- wm". Is it right to do this? Or this may compromise my data? Thanks in advance, Alberto.

The resulting longitudinal WM surface for both time points excludes large parts of the cortex. The cross sectional surfaces and the wm.mgz are correct. The base wm.mgz also seems to be fine, however, the base white and pial surfaces do not follow the wm volume properly. We have rerun the longitudinal anlaysis (recon-all -long) according to the cheat sheet: 1. marking the base wm.mgz border with 255 voxel value (instead of 110) 2. adding control points to the base wm.mgz but it did not change the original result.

Post-doctoral Positions in Affective Neuroscience at McLean Hospital/Harvard Medical School
by Poornima Kumar 01 Oct '15

01 Oct '15

Two post-doctoral positions are available within the Laboratory for Affective and Translational Neuroscience at McLean Hospital/Harvard Medical School, directed by Diego A. Pizzagalli, Ph.D. The laboratory is part of the Center for Depression, Anxiety and Stress Research (CDASR), a vibrant research center that embraces a multi-disciplinary approach to improve our understanding of the psychological, environmental, and neurobiological factors associated with depression, anxiety and related disorders across the lifespan ( http://cdasr.mclean.harvard.edu/) Currently ongoing studies in Dr. Pizzagalli’s laboratory focus on reward processing, stress responsivity, and executive functioning in a range of populations including individuals with major depression, mood spectrum disorders, as well as at-risk samples (e.g., offspring of parents with MDD; individuals with past MDD). These studies employ a variety of approaches, including high-density EEG, fMRI, PET, MRS, molecular genetics, and assays of hormonal/inflammatory markers, and often a treatment component (e.g., CBT). Opportunities will be available to pursue independent research and interdisciplinary collaborations across Harvard Medical School. Depending on research focus, candidates will have access to three research-dedicated human MRI scanners (3 T, 4 T) and one animal MRI scanner (9.4 T), as well as 128-channel EEG systems. A strong background in EEG/ERP or fMRI techniques is required, and clinical training is a plus.
