visualizing statistical maps in FreeView
by Lars M. Rimol 24 Jun '16

24 Jun '16

Hi, Is it possible to overlay .mgh files with statistics (e.g. p-maps) directly in FreeView, for purposes of visualizing the results, the same way you can in tksurfer? When I try load an overlay in FreeView, it seems to be expecting a volume file. Thank you! sincerely yours, Lars M. Rimol, PhD Senior researcher, Norwegian Advisory Unit for functional MRI Department of Radiology, St. Olav's University hospital, 7006 Trondheim, Norway

Creating spheres in the volume
by Afzal, Afsana 24 Jun '16

24 Jun '16

Hi, This question might have already been answered before but is there a way to take a coordinate in MNI space and create, say, a 5mm sphere in the volume? My goal is to take the sphere in the volume and convert it to a label using something like mri_vol2surf. Thanks for your help, Afsana ______________________________ Afsana Afzal Clinical Research Coordinator Massachusetts General Hospital Division of Neurotherapeutics Department of Psychiatry: Neurosciences 149 13th St, Room 2612 Charlestown, MA 02129 Phone: 617-643-5129 Fax: 617-726-4078

patch error
by S.V.Shepherd [work] 23 Jun '16

23 Jun '16

Hello all, I'm trying to make a patch and have run into the 'bad vertex' error. It's come up a few times on the listserv, but I never saw a public resolution. One possible source of errors is that I had to do a manual correction in FreeView, including a 'remove intersections' in FreeView. However, tksurfer had no trouble mapping the curvature to the finished surface, so I assume this was not likely to be the source of the error. Details below: $ mris_flatten -w 0 -distances 20 7 lh.cort.patch.3d lh.cort.patch.flat using write iterations = 0 sampling 7 neighbors out to a distance of 20 mm reading patch lh.cort.patch.3d with 1919246708 vertices (2846533.5% of total) MRISreadPatch: bad vertex # (1701060705) found in patch file No such file or directory stephen *stephen v. shepherd phd* The Rockefeller University / 1230 York Avenue / New York NY 10065-6307 USA // 212.327.7699

Qdec
by j.anderson＠publicist.com 23 Jun '16

23 Jun '16

Dear Freesurfer experts, I wanted to run cortical thickness analysis between two groups to check the diffetence in thickness between the groups. I used Qdec My question is regarding correcting for multiple comparisons. There are two options FDR and montecarlo. Which option do you recommend? Are there any role that can force the analysis to be corrected with any of them Thanks John

recon-all warnings
by Rockers, Elijah D. 23 Jun '16

23 Jun '16

Hello, Doing a recon-all -all yields some deprecation warnings. defined(@array) is deprecated at /freesurfer/mni/bin/nu_estimate_np_and_em line 165. Use of ?PATTERN? without explicit operator is deprecated at /freesurfer/mni/bin/sharpen_volume line 153. I think my results should still be OK because it's a warning, but I just wanted to make sure.

Converting fsaverage to MNI space
by Skyler Gabriel Shollenbarger 23 Jun '16

23 Jun '16

Hi FS community, I am trying to convert fsaverage to MNI space. The command did not produce computation errors, however the output file is upside down (not L-R reversed). Any thoughts on how to orient the output correctly (see attached pictures for output file)? mri_vol2vol --mov fsaverage.DKT40+aseg.nii --targ /usr/local/fsl/data/standard/MNI152_T1_2mm.nii.gz --o fsaverage_MNI_DKT40+aseg.nii --interp nearest --reg /Applications/freesurfer/average/mni152.register.dat Thank you for your time, Skyler
