Problem with template longitudinal pipeline
by Laura van Velzen 09 May '18

09 May '18

External Email - Use Caution Dear FreeSurfer experts, We are trying to run FreeSurfer v5.3 on our longitudinal imaging data using the longitudinal pipeline. We first processed both time points cross-sectionally. The output of this step looks fine for both time points. We then performed step 2: creation of a template from both time points and step 3: longitudinally processing both time points. All steps run without errors, but the output of steps 2 and 3 look abnormal (please see images attached), so there appears to be something wrong in the creation of the template. We also have some subjects with data from only one timepoint and ran the longitudinal pipeline for these subjects as well (as was recommended on the wiki) and the output of steps 2 and 3 look fine for these subjects, so there appears to be an issue in creating the template based on both time points. The acquisition parameters at both time points are the same as far as we know. There is nine years between both measurements, and most of our subjects are between 50 and 60 years old at the second measurement. We have attached the recon.all.log file for one of our subjects. We hope you have some suggestions what the problem might be and how we could check this. Many thanks in advance for your help! Kind regards, Laura van Velzen & Julia Binnewies

-cw256 flag in recon-all
by JAVIER ROJO MUÑOZ 08 May '18

08 May '18

External Email - Use Caution Hello FreeSufer developers, We're trying to have a small quality control pipeline when executing recon-all. As a part of this, one doubt came to us, and couldn't find an answer: Is the -cw256 flag applied always or only when the FOV is larger than expected? Also, when executing -autorecon1 and -autorecon2 separately, should we use this flag only in -autorecon1 or also in -autorecon2 and -autorecon3? I tried applying only to -autorecon1 and it worked apparently, but I don't know if I'm missing something. We're using the following version of Freesurfer: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c I would be more than grateful for any help, and sorry if that might be a lame question. Sincerely, Javier Rojo MuÃ±oz -- JAVIER ROJO MUÑOZ Universidad Politecnica de Madrid

Re: [Freesurfer] transforming functional volumes to MNI without resampling
by David Beeler 08 May '18

External Email - Use Caution Alright thanks, mri_coreg looks a little better than bbregister. But similar to bbregister, using 6 dof results in a brain that is a little too small and using 12 dof has both scaling and translation issues. What would be the way to use CVS?

Longitudinal hippocampal subfields analysis problem

Re: [Freesurfer] Extracting DTI/NODDI data from hippocampal subfields
by Iglesias Gonzalez, Eugenio 08 May '18

08 May '18

External Email - Use Caution Dear Mark, Just to make sure we’re on the same page: I’ll say that two images are in the same voxel space when they have the same size (in voxels, e.g., 256x256x256) and the same vox2ras matrix - the one that maps voxel coordinates to RAS (physical) coordinates. The subfield segmentation is indeed in the same RAS coordinates as your native T1, but not in the same voxel space. One option that you have is to convert your subfield mask to the voxel space of the T1, with the option –rl (“reslice like”) of mri_convert: For probabilistic masks: mri_convert subfield_prob.mgz subfield_prob_T1voxelSpace.mgz -rl norm.mgz -odt float For discrete masks or segmentations, you can use a similar command, but with nearest neighbor interpolation: mri_convert subfield_mask.mgz subfield_mask_T1voxelSpace.mgz -rl norm.mgz -odt float -rt nearest I hope this helps!

I am just getting my feet wet with running my subjects through the Freesurfer processing stream, so the following question night be a bit trivial (I hope): I have run qvlSegmentHippocampal subfields on one of my subjects, and it completed just fine with what seem to be the appropriate outputs in the subject’s mri folder. I have another 100 subjects to run, but want to make sure I can accomplish what I would like to on this subject first. The images which I see are sub-images, i.e. these have fewer voxels compared to the original image, but in the native T1 space resolution (= 1 mm3). I would now like to register the subfields in the native space (my DTI/NODDI maps are already registered into this space), to obtain mean values within each subfield. How can I transform these sub-field images back into the native T1 space, or is there a method within Freesurfer to perform the math (e.g. similar to fslmaths)?

Non-parametric correlation between FC and neuropsychological/volumetric outcomes
by stdp82＠virgilio.it 08 May '18

08 May '18

Hi list, which the best way to perform a whole-brain correlation of the FC assessed by FS-FAST with the volumetic or neuropsychological outcomes? Please note that my question is specifically addressed to those factors (neuropsycholgical scores or volume of seed) did not show a normal distribution and that cannot be trasformed. Thanks Kind regards Stefano

N3 kernel decrease
by Rebecca Ray 07 May '18

07 May '18

External Email - Use Caution Hello, I am working on T1 images from multi-sites. One site in particular is producing T1s that have small to large areas of temporal cortex being excluded from segmentation. It seems that there may be an issue with inhomogeneity of the bias field and subsequent over correction. I have 2 scans from each person and the 2nd scan is worse. The second scan from one subject refuses to finish the freesurfer pipeline. It seems to boom out right before segmentation. I was told to decrease the bias field correction smoothing kernel but have not found where to do that on the Wiki. How do I add that syntax? Thanks. Rebecca
