Hello Anastasia, I’m using the nightly-built version for Mac OS Lion; I double checked it by the command freesurfer -ver and got this response: You are running this version of FreeSurfer: freesurfer-Darwin-lion-dev-20150227 I’m using this version on Mac OS X Yosemite. I tried to re-download a nightly built version, but it didn’t let me (presumably because it’s workshop time). Please let me know how I should proceed.

[Freesurfer] Applying a precomputed transform matrix to an image in free surfer
Hello, I’m having a volume (e.g. dtifit_FA.nii.gz) and a transform matrix (e.g. diff2anatorig.bbr.mat), and I want to apply the transform matrix to the image and generate a transformed image. This is a general question I’m having, but in this particular case, I want to apply the transform matrix (from diffusion space to the anatomical space generated by TRACULA) to the FA map to generate a transformed FA map that can be overlaid on the anatomical images. I wonder if I have to use mri_vol2vol command for doing this, and I don’t know how to provide it with appropriate flags. I’m already having the transform matrix generated by TRACULA (and I don’t want to change it; I just want to apply it to the image!). My crude guess would be something like this: mri_vol2vol --mov --o --reg diff2anatorig.bbr.mat Please let me know how I should run this command. Thank you very much, Emad P.S. I know that for this particular example, I can use the anatomical images in dlabel/diff, but the point for me is to learn how to apply a transform matrix to an image and generate a transformed image in freesurfer Emad Ahmadi, MD --- Postdoc Research Fellow Department of Radiology Massachusetts General Hospital Harvard Medical School 25 New Chardon Street, Suite 400 Boston, MA 02114 Tel: 617 726 5237 Email: e...@nmr.mgh.harvard.edu___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

[Freesurfer] Is the x-component of the b vectors extracted by mri_convert inverted?
Hi FreeSurfer Experts, Happy New Year! I am using mri_convert to extract b vectors (bvecs) from diffusion images obtained at Bay 4. Then I use TRACULA for reconstructing white-matter pathways. The shape of the reconstructed pathways are odd, so I checked if the extracted bvecs are correct. To check if the extracted bvecs are correct, I used Diffusion Toolkit together with the extracted bvecs to do deterministic tractography. Then I checked the shape of the extracted nerve fibers. I have put a slide deck in the following dropbox folder showing that the shape of the extracted nerve fibers don’t look right: https://www.dropbox.com/s/1bt6on0rwm9url6/x_inversion.pptx?dl=0 <https://www.dropbox.com/s/1bt6on0rwm9url6/x_inversion.pptx?dl=0> Then I inverted the x-components of the extracted bvecs, and did the tractography again. This corrected the shape of the extracted nerve fibers (see the slide deck). I additionally had a look at the extracted dtift_V1 vectors under the two conditions, i.e. before and after x-component inversion. The results showed the same thing: x inversion corrects the images. I just wanted to see if others have had the same problem and confirm that I should invert the x-component of the bvecs extracted via mri_convert (I had the same experience with dcm2nii tool, where I had to invert the z-component of the extracted bvecs). I hope a wonderful new year for everyone!

[Freesurfer] Longitudinal TRACULA - Error in path reconstruction

[Freesurfer] Unpacking Problem
Hello,I’m trying to unpack and run recon-all on a set of MEMPRAGE images we’ve obtained in Lunder 6 scanner (Siemens Skyra), but recon-all is giving me errors. I’ve attached for the scan.info file (outputted by unpacksdcmdir), the unpack.config file that I used to unpack the MEMPRAGE images, and the recon-all.log file containing the error that recon-all command gives me. I’m running recon-all on in MEMPRAGE3 folder containing MEMPRAGE_IPAT3 RMS images. Please let me know if I have to provide any further info about this problem.Thank you very much for your help,EmadEmad Ahmadi, MD---Postdoc Research FellowDepartment of RadiologyMassachusetts General HospitalHarvard Medical School25 New Chardon Street, Suite 400Boston, MA 02114Tel: 617 726 5237Email: e...@nmr.mgh.harvard.edu scan.info Description: Binary data unpack.config Description: Binary data recon-all.log Description: Binary data ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

[Freesurfer] Dura correction using MEMPRAGE vs bandwidth-matched FLAIR
Hi,We are at the start of a study on TBI, in which we’re obtaining MEMPRAGE and T2-SPACE-FLAIR images (the images are obtained in Lunder 6 scanner, and I wonder if I can find T1 & FLAIR matched sequences for morphormetry on that scanner). The pixel size of the MEMPRAGE sequence is 1mm isotropic, while the one for T2-SPACE-FLAIR is 0.5 x 0.5 x 1mm; they’re not bandwidth matched either (I’ve attached the details of the sequences we’re using). I just wanted to know if we should make changes to our T2-SPACE-FLAIR sequence and match it with the MEMPRAGE sequence to feed the FLAIR images into recon-all for dura correction, or if we should leave the T2-SPACE-FLAIR sequence as it is and use the four echoes of MEMPRAGE for dura correction (I mean, is dura correction using different echoes of MEMPRAGE as good as feeding FLAIR images into recon-all?)Thank you very much,Emad Emad Ahmadi, MD---Postdoc Research FellowDepartment of RadiologyMassachusetts General HospitalHarvard Medical School25 New Chardon Street, Suite 400Boston, MA 02114Tel: 617 726 5237Email: e...@nmr.mgh.harvard.edu SIEMENS MAGNETOM Skyra syngo MR D13 - \\USER\RESEARCH\Gupta_Research\Main Sequences\MEMPRAGE_IPAT3 TA:4:28 PAT:3 Voxel size:1.0Ã1.0Ã1.0 mm Rel.
