Strange looking dtifit_FA.nii.gz in FreeView
by Linnea Marie Dramdal Borg 20 Sep '17

20 Sep '17

Hi, We have run TRACULA on a couple hundred subjects and the quality control shows that most of them are OK, but in a few subjects the dtifit_FA.nii.gz images look strange in FreeView. The image intensities appear reversed in FreeView (see freeview_T207_dtifit_FA.nii.gz.png) but look normal in Fslview (see Fslview_T207_dtifit_FA.nii.gz.png). T205 is an example of a subject that looks normal also in FreeView (see fslview-freeview_T205_dtifit_FA.nii.gz.png), as most of our subjects' dtifit_FA images do. 207's dwi_orig image looks fine in FreeView (see freeview_T207_dwi_orig.nii.gz.png) as do all its L1,L2,L3,V1,V2,V3 etc. images. I'm puzzled as to what has happened here. Since the image looks fine in Fslview I'm inclined to think this is a FreeView issue? Thank you, Linnea Marie

Freeview Strange Behavior
by Torrado Carvajal, Angel 20 Sep '17

20 Sep '17

Good morning, We have been experiencing a weird behavior in Freeview when loading non local images. For example, if I try to load images located in simba or mrs from nemo, I get something like the attached screenshot. If I copy the file locally, I don't see this behavior. Marco also tried on his computer, replicating the same strange behavior. Any ideas on why this is happening? Thank you very much! Best, -- Angel Torrado-Carvajal Postdoctoral Research Fellow Pain Neuroimaging Laboratory MGH/HST Athinoula A.

Re: [Freesurfer] Pial surface volume

Dear Professor Bruce I'm just trying to convert lh.pial surface to the volume with the down below command but the output doesn't make any sense ( lh.voulme contains zero). Could you please help?

morphing ?h.cortex.patch.flat to sample subject

Hey all I'm trying to morph the fsaverage flat patch (?h.cortex.patch.flat) to the freesurfer sample subject, and getting the following error: mri_surf2surf --srcsubject fsaverage --srcsurfval lh.cortex.patch.flat --trgsubject sample --trgsurfval lh.cortex.patch.sample.flat --hemi lh ERROR: could not determine type of lh.cortex.patch.sample.flat mris_convert also didn't work: mri_surf2surf --srcsubject fsaverage --srcsurfval lh.cortex.patch.flat --trgsubject sample --trgsurfval lh.cortex.patch.sample.flat --hemi lh ERROR: could not determine type of lh.cortex.patch.sample.flat [thibault:surf] (nmr-stable53-env) mris_convert lh.cortex.patch.flat lh.cortex.patch.flat.asc mrisFindNeighbors: lh.cortex.patch.flat: face[0].v[0] = 0, but face 0 not in vertex 0 face list I could read it using the python code in pyCortex: https://github.com/gallantlab/pycortex/blob/00cc7dadd16149ac7f6fe38621c95c4… And after that save it as a freesurfer surface: https://github.com/gallantlab/pycortex/blob/00cc7dadd16149ac7f6fe38621c95c4… But even after that mri_surf2surf couldn't determine the type. Any ideas? Thanks, Noam

Hello Freesurfer users, I am trying to run recon -all basic pipeline on CentOS x86-64 - Freesurfer v5.1.0 . I face the similar error as reported earlier by other users. nifti1Read(): unsupported slice timing pattern 5 In the previous archives, there are links provided, which are currently not accessible or are dead links. Can I please have the correct file/link to avoid this error. Thank you, Jyothirmayi Vadlamudi University of Louvain (UcL) Belgium.
