Get center coordinates of ROIs from the Lausanne2008 parcellation
by Laura Juan Galmes 14 Mar '18

14 Mar '18

Hi all, I have a question about how to get a .nii or .mgz file out of a .gcs. What I actually want to do is get the coordinates of the centroids of the regions of my atlas ( which is lausanne2008), or even the coordinates of all the voxels in each region so I could compute the mean myself. However, I only have the gcs files (myatlas_125_rh.gcs and my atlas_125_lh.gcs) and have no idea on how to get this information. Thank you a lot in advance. Laura

dt_recon error: MatrixReadTxT: could not scan value [1][1]
by Noriana Jakopin 13 Mar '18

Hello FreeSurfer Developers, I am trying to follow the diffusion processing pipeline describe in this tutorial: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/DiffusionV6.0#dMRIData… However, I keep getting an error when using dt_recon. For background, my input is 1700 dicom images. The code seems to run the Eddy/Motion Correct part. Once it reaches Fitting Tensors, I get the following messages: ---------------------- Creating output directory /mnt/c/Users/leonardo/Desktop/UMD/Linux-Windows/Hedyeh/MIDA_dtrecon Loading y from /mnt/c/Users/leonardo/Desktop/UMD/Linux-Windows/Hedyeh/MIDA_dtrecon/dwi-ec.nii.gz ... done reading.

Negative areas in mris_sphere, dark in freeview
by Chris Adamson 13 Mar '18

13 Mar '18

Freesurfer devs, I have a baffling problem in mris_sphere. I have generated some surfaces using an external tool that uses VTK. After converting the surfaces into freesurfer format using a basic format converter, then adding volume geometry to the surface file using the image used to create it the surface appears dark in freeview. When I do mris_inflate followed by mris_sphere, mris_sphere says nearly all the triangles have negative area at the end and it never finishes. I verified in MATLAB that the surface normals (computed by mris_convert) of the original white surfaces point outwards. The darkness in freeview is not fixed by changing the order of the indices of the faces (which should invert the normal). I'm at a loss to explain this. Thanks in advance, Chris.

running -hippo-subfields with both T1 and T2 using FS 6.0
by Alexopoulos, Dimitrios 13 Mar '18

13 Mar '18

I need a clarification with the command to run for generating the hippo subfields on 6.0 using both a T1 mprage and T2 space (both 1mm isotropic). I'd like to run the entire recon-all -all surface and hippo subfields processing stream. Would this be the correct command: recon-all -s subject -i dicom.dcm -hippocampal-subfields-T1T2 T2.nii.gz T1T2 -all Thanks.

Hi Kai, please remember to post to the list. Your FSGD file is not quite right. Gender is a discrete variable and should be represented by two groups not as a covariate.

FreeSurfer Error Edit Sequence

Hello Experts, Do you suggest FreeSurfer users to *strictly* follow the *error edit sequence* (Brain Mask --> WM --> GM --> Control Points) listed here (link below)? https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TroubleshootingData If not, can users follow this sequence instead: Brain Mask --> Control Points --> GM --> WM? The justification here is to minimize the time spent to perform hand edits. Thank you for your time, -- David S.
