FreeSurfer load nifti error
by Siamak Sorooshyari 01 Feb '23

01 Feb '23

External Email - Use Caution Dear FreeSurfer, I am using the FieldTrip software to process MEG data, it involves my using the function ft_read_mri() in MATLAB to read in the anatomical MRI file. I have tried feeding into this function a .nii.gz as well as the unzipped .nii version. In the latter case I get an error: ERROR: D:\...\anat\sub-0249_ses-01_run-1_T1w.nii, read in 21626880 voxels, expected 10813440 I contacted the FieldTrip folks and they mentioned that it's a FreeSurfer issue. I think I've isolated the issue to the load_nifti.m file with the "nitemsread" variable and "nvoxels" variables not matching in value. I am not clear why this would happen, how can this be fixed? Best, Siamak

Correlating two modalities in group-level surface-based analyses
by Betsy Bartlett 01 Feb '23

01 Feb '23

External Email - Use Caution Hello, Does Freesurfer offer the option for group-level surface-based vertex-wise analyses comparing two imaging modalities? For example, I want to find clusters of vertices where cortical thickness and a PET, DTI, or fMRI measure mapped onto the surface are significantly correlated in my cohort of subjects. If this is possible in Freesurfer, is there any existing documentation you could point me to for setting up the fsgd and contrast files? Thank you!

Re: [Freesurfer] Skull stripping with external brainmask
by Iglesias Gonzalez, Juan E. 30 Jan '23

Dear Narlon, I believe you can add -xmask [mask_volume_file] to your recon-all command. To generate such external mask, maybe you could use mri_synthseg with the --robust flag and binarize the output?

It seems like the conventional approaches (e.g., adjusting -wsthresh) doesn’t seem to help. As well, applying these preprocessing steps to the raw T1w BEFORE processing in FreeSurfer doesn’t seem to help either. I have tried: intensity truncation, N4 bias field correction, data normalization (with different combinations). Considering that we’re analyzing data from a large dataset (>500 scans * multiple timepoints), manual editing may not feasible. Therefore, to address poor skull stripping, I was wondering if it is possible to use a brain mask created outside FreeSurfer for the same subject to help with skull stripping. I saw in previous emails in the Archive that the steps below could work. Can someone confirm if this is still true and would work for v7.1.1? 1. run recon-all (as one normally would) 2. apply mri_mask to mask the T1.mgz with external brain mask volume (in native space) 3. name the output “brainmask.mgz” and move it to "subjid/mri/“ 3. re-run recon-all starting from -autorecon2 -autorecon3 Thanks for your help!

A doubt regarding autorecon after watershedding
by Rakshathi Basavaraju 30 Jan '23

30 Jan '23

External Email - Use Caution Dear FS, I intend to examine cortical thickness correlates of negative symptoms in my schizophrenia sample. I ran recon-all and corrected a few brainmasks which were excessively stripped by watershedding with different h values (ran autorecon-pial for those watershedded). I am attaching a few screenshots of scans where the segmentation is erroneous and the aseg omits the right temporal and parietal or cerebellar regions. How do I set this right?
