Missing values in fsgd file
by Jennifer Szeto 20 Dec '16

20 Dec '16

Hi freesurfer experts, I am trying to run some mri_glmfit analyses on freesurfer5.3. However there are some missing values in some of my fsgd files due to missing data in my dataset. Is there anyway we can run mri_glmfit analyses with missing values in fsgd files? Thank you very much, Jennifer

pial surface errors - V6beta
by Antonin Skoch 20 Dec '16

20 Dec '16

Dear experts, in my data I quite often encounter errors in pial surface which is probably induced by errors of white surface, in some cases caused by juxtacortical lesions (even in healthy subjects). See screenshots for examples. I have tested this on freesurfer V6 beta but it is commonly also found in older versions. I have uploaded the subject pial_errors.tar.gz to your server. The error showed pial_error1.png in probably caused by small error in white surface shape in 18,-18,63 (RAS). Another similar problem is in 15,10,53 (RAS). This is probably caused by juxtacortical lesion. Another problematic spot with juxtacortical lesion is on -7,18,47 (RAS). I have observed such kind of errors in quite a large number of subjects, these are either healthy controls or subjects with psychiatric ilnesses, therefore no particular apparent macroscopic pathology should be present in these subjects. Do you think that there could be some improvement in the mris_make_surfaces code to prevent this kind of behaviour (i.e. very small error in white has gross effect on pial), or it is necessary in all these cases to manually intervene ? Especially, I do not see any particular problem in image in case of pial_error1.png. And, in case of editing of problems errors by juxtacortical lesions I find fastest way to edit wm (due to the fact that I can constrain the brush not to draw to existing wm) in contrast to editing aseg (i.e. label the spot as a lesion). Do you think that aseg editing in contrast to wm editing has some benefit in this case? Regards, Antonin Skoch

Help on ringing artifacts
by Wayne Su 20 Dec '16

20 Dec '16

Hello Experts: I encountered one big issue with cortical segmentation by using Freesurfer. See the image I attached. There are some hyper-intense thin white surface strip at the edge of cortex. Sometimes Freesurfer misclassified them as white matter. Even not, I am not sure whether those are gray matter or not. Anyone knows what are they, and what caused this ³artifacts²? Is there a way to get rid of them on the scanner? I appreciate anyone points me to the right direction. Regards, Wayne

Hello, FreeSurfer experts: I know that we are going to have a new version of FS 6.0.0, but with the curent newest version of TRACULA(trac-all,v 1.56 2014/05/26 08:28:32 ayendiki Exp ) for FS5.3.0, I am working on UBUNTU14.0.

Talairach error in monkey brain
by Qi Ting 19 Dec '16

19 Dec '16

Dear Freesurfer experts, I'm using freesurfer to process my monkey brain data. It reported errors during Talairach registration step. So I added no-tal-check tag to run recon-all autorecon1 and used tkregister2 to manually edit registration. However, I couldn't let them perfectly fitted, especially deformation in sagittal view. But when I checked the final parcellation, I found it worked well. So I was wondering whether the Talairach registration step matters a lot for the final results? And whether I did correctly? Thanks in advance! with best regards, Ting Qi

Poorly Designed Matrix Two Stage Longitudinal Model
by Timothy Hendrickson 19 Dec '16

19 Dec '16

FreeSurfer experts, I am attempting to use the two stage model for longitudinal analysis, however I keep receiving an error message that my design matrix is poorly scaled. I'm curious, I've used the same format of design matrix on cross sectional without problem. Anyway here is the command line input: mri_glmfit --glmdir rh.AllSite.gender.group.Age.thickness.fwhm10.twoStage.glmdir \ --X DOSSDS.twoStage_AllSite_Gender_Group_Age.dat \ --y rh.testretest.thickness-spc.stack.fwhm10.mgh \ --C DiffDiagnosis_ControlMore_AcctSite_AcctGender_AcctAge_pairedAnalysis.DOSSDS.mtx \ --label rh.testretest.fsaverage.cortex.label \ --surf fsaverage rh The error message is attached within file error_designMtx_12_19_16.txt Additionally I've included my analysis script, all timepoint qdec file, temporal average qdec file, fsgd file, and design matrix. Any help would be extremely beneficial. -Tim Timothy Hendrickson Department of Psychiatry University of Minnesota Office: 612-624-6441 Mobile: 507-259-3434 (texts okay)

TRACULA to define multiple bvals
by Hao wen 19 Dec '16

19 Dec '16

Hello, Freesurfer experts: I want to ask you in TRACULA, we can define multiple bvecs with the variable 'bveclist' in configuration file, so my question is if we have the same option for bval, or it is mandatory to have the same bvals for all the subjects??? I dont see any information about this... Thanks in advance Hao

lh.cst_AS_avg33_mni_bbr rh.cst_AS_avg33_mni_bbr ' and in the output structure /dlabel, I dont have the mni sub-folder, so I guess I have some problems when doning the tensor fitting. And I know in this process, we will need the aparc+aseg.mgz, but the in the tutorial data diffusion_recons , for the subject of elmo.2005, I dont find aparc+aseg.mgz in mri folder, and I just found aparc+aseg2diff.mgz image in Diff001, instead, you use this volume??? I am stuck at this step, any advice will be appreciated:) Thank in advance Hao Good day

Own ROI for cortical thickness measurements

Dear Freesurfer-experts, I want to create my own ROI for purposes of cortical thickness measurements in Freesurfer. As input, I have a binary_volume_mask.mgz. But I'm lacking to get this mask as a label or volume into the FS structure. I already tryed the mri_vol2surf and mri_vol2roi, unfortunately without successs. Looking forward to hearing your suggestion, Best, Andreas Niebuhr ............................................................................ .....
