Hi Bruce, Did you mean an updated version of mri_parcellate? If so, it would be great. Thanks! -------------------------------------------- Hi Fengji this is a known bug in mris_parcellate.

Hi, I have a large amount of data (FS scanworkups) where all the files within every subject's directory are zipped. Is there a way to run mris_preproc on zipped data? For instance, mris_preproc crashes because it can't find lh.thickness unless I unzip it Thank you! sincerely yours, Lars M.

wm correction

Hi Bruce, I am editing a brain with Freesurfer version 5.3. I have a issue in Lateral Ventricle. As you can see in the image attached, the big part is excluded in both hemisphere. I tried to fill it by editing wm volume but the problem still exists.Do you have any suggestion?Thanks,Maryam test_vumc_158_rh.png test_vumc_158_lh.png

mail option to email custom status of job completion
by Sneha Pandya 27 Jan '16

27 Jan '16

Dear experts, I usually setup batch jobs for my studies and use '-mail' option that emails me completion of recon-all with or without errors. Is there a way or any other option that I can use alongside '-mail' to give me custom status message than the usual one which says "recon-all -s XYZ finished without error at ...". For example if I have set up to run subjects XYZ for only autorecon2 stage, I would like it to send me an email message saying "recon-all autorecon-2 finished without error" or something? Thanks, Sneha

You can do this in 3 ways: 1. mri_annotation2label --lobesStrict 2. mri_annotation2label --lobes 3. Custom: break up annotation and recombine: a. mri_annotation to create separate label files b. mri_mergelabels to create single label files for each lobe label c. mris_label2annot to create the lobe annotation Next, create the WM segmentation with mri_aparc2aseg, specifying your new lobe annot and adding --labelwm. You can control the distance with --wmparc-dmax doug

Ex-Vivo Brain: Dark Surface in Freeview; Bad Surface Registration
by John Plass 27 Jan '16

27 Jan '16

Hello, I've been following the Ex-Vivo Recon instructions https://surfer.nmr.mgh.harvard.edu/fswiki/ExvivoRecon) with an MPRAGE scan of a formalin-fixated brain. With considerable manual editing, I've been able to produce convincing white and pial surfaces, but I am having trouble getting a good parcellation. The labels are reversed from anterior to posterior (e.g., superior parietal lobule area is labelled as middle frontal gyrus). I am assuming this has to do with problems with the surface registration. Also, when viewing the surfaces in Freeview, they appear pretty dark (perhaps similar to https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-June/018689.html) although the correspondence between red/green and gyri and sulci appears to be correct. Might this be part of the problem? Any advice would be much appreciated! If you'd like to take a look at the files, please let me know what and where to upload. Thanks very much for your help. Best regards, John Plass

R: Ref FAST and results visualization issue
by stdp82＠virgilio.it 27 Jan '16

27 Jan '16

Briefly, is possible to map the fictional connectivity between a right seed and left cortex? Stefano ----Messaggio originale---- Da: stdp82(a)virgilio.it Data: 27-gen-2016 18.57 A: <freesurfer(a)nmr.mgh.harvard.edu> Ogg: [Freesurfer] Ref FAST and results visualization issue Hi list, I have two requests please. A- I need to have a reference for FS-FAST (seed based analysis on rs data) B- I have difficulties for results visualization. How can I do to visualize the the cortical areas which are functionally connected with the controlateral seed? For example, my seed are right and left amygdala.To visualize RIGHT amygdala - RIGHT cortex connectivity I'm doing: cd my-group/fc.ramgseed.surf.lh/R_Amygdala tksurfer fsaverage rh inflated -aparc -overlay my-glm.wls/intercept/sig.nii.gz and all is fine. To visualize RIGHT amygdala - LEFT cortex connectivity I'm doing: tksurfer fsaverage lh inflated -aparc -overlay my-glm.wls/intercept/sig.nii.gz but the image is so confused. It seem to be the translated image which I have projected in the right semi. Thanks Stefano

watershed bem surface problems
by Keith Doelling 27 Jan '16

27 Jan '16

Hi All, I'm trying to source localize MEG data in MNE-Python but have run across an issue with a subject's MRI in the freesurfer watershed algorithm. Namely, the outer skull surface ever so slightly overlaps with the inner skull (I've plotted this in freeview for your viewing pleasure). This is a problem as MNE stops with an error in the make_bem_model function when such overlap occurs (understandably). I have tried deleting the bottom slices of the T1.mgz and rerunning the watershed algorithm but that actually made the overlap worse. I have also tried using the -atlas parameter which made it a bit better but not quite (that's actually what is plotted). What I would really like to do at this point is manually edit the surfaces to avoid the overlap which I think given the location and minuscule nature of the overlap. Any tips on how to get this done? Or on how to edit the MRI to avoid this overlap to begin with? Thanks for your help!
