question about voxel size
by Dorsa Haji Ghaffari 19 Jul '16

19 Jul '16

Hi, I have a T1 weighted MRI which I want to segment using Freesurfer. The voxel sizes are 0.48*0.48*0.48. I read that the ideal voxel size for freesurfer is 1mm^3. Is there any manual adjustments that I can make to get good results with my 0.48 voxel size images? Thank you Dorsa Ghaffari

vtk to mgz file
by Abbie McNulty 19 Jul '16

19 Jul '16

So we were able to figure out how to segment the different parts of the brain using the bert sample, but have run into another problem. I would like to save each segmentation so that I can import it into matlab and create a matrix in order to create a mesh. The volume segment saves a as a .vtk file, which I don't know how to read into matlab. How can I save it as or convert it to a .mgz file so that I can import it into matlab? Thanks!

mriBuildVoronoiDiagramFloat - argument out of domain
by Uquillas, Federico D'Oleire 19 Jul '16

19 Jul '16

Dear fellow Freesurfer users, I have 4 jobs that have failed with the following after submitting -recon–all –autorecon2 –autorecon3 for skullstip edits, and control points: mriBuildVoronoiDiagramFloat Incorrect input type(s): Numerical argument out of domain. Wondering what this means? I’m attaching one of these log files as all 4 exited with the same. Thank you for any input you may be able to provide. Best, Fred

recon-all exited with erros
by Salem Hannoun 19 Jul '16

19 Jul '16

Hi I’m trying to run free surfer on a set of T1 images. I tried to do it on one patient first before running it on the whole dataset. I ran the recon-all with the -all option I had an error message one minute after it has been launched. It stopped at the mri_nu_correct.mni. Could you please advise on how to fix this error? Please find below the log file Thank you for you help Best regards Salem _____________________________________________ Fri Jul 15 10:20:05 EEST 2016 /usr/local/freesurfer/subjects/AZH

3 analyses questions
by Caroline Beelen 19 Jul '16

19 Jul '16

Dear FS team, I would like to correct for multiple comparisons after I run command-line GLM analysis on aparc.stats tables (my ROI's are few regions from DK-atlas). I tried to do the Monte Carlo simulation but get an error that a masking-file is missing. In general, how could I correct for multiple comparisons when using aparcstats2tables in GLM? Alternatively I performed the analysis in Qdec (excluding a nuisance factor to be able to do so). I tried to implement few ROI's from DK-atlas, one at a time, such as left fusiform area. However, when running the analysis it seems to take into account the whole area of the brain and investigates its correlation with a particular selected ROI (i.e. left fusiform area). Would this kind of analysis give me the same results as when only performing stats on this particular region? Actually, for my analysis I'm only interested in few regions of DK-atlas and, if possible, would like to perform it on only these regions, leaving out all of the rest (I'm correcting for ICV anyways). In that case I would also have to correct for fewer multiple comparisons... How could I achieve this in Qdec and/or command-line GLM? Thanks in advance for your help. Regards, Caroline

Re: [Freesurfer] question about voxel size

Hi Dorsa, well visual inspection is always a good indicator. Also you could have a look at the QA Tools (https://surfer.nmr.mgh.harvard.edu/fswiki/QATools) I haven’t tested them though. Other than that, I wouldn’t know of any objective method to validate your results. Probably someone else can jump in on that. Best, Falk P.S. Be sure to also reply to the list also.

I was actually able to get results using my high resolution images without changing their resolution. Is there any way to validate my results to see if I have good results?

With FreeSurfer v6 this workaround will not be necessary anymore, as the processing pipeline has been updated. If you want to, you could also try out a recent developer build. However, it is still under development.

I read that the ideal voxel size for freesurfer is 1mm^3. Is there any manual adjustments that I can make to get good results with my 0.48 voxel size images? Thank you Dorsa Ghaffari

Bug in Freesurfer Installation

Hello freesurfer developers, I installed FreeSurfer on my computer today using the instructions found here: https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall. After installation, I proceed to the “test your FreeSurfer Installation” section. Upon trying the first test, I ran the following and code and received the following error.

T2 vs. T2-FLAIR update
by Michelle T Kassel 19 Jul '16

19 Jul '16

Hello, I am beginning a new study and would like to determine the optimal T2 acquisition parameters for improved pial surface results from FreeSurfer. I am wondering if there is a difference in using a T2 or T2-FLAIR. I have found a discussion post from 2014 which provided useful information (https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2014-July/039580.html) however, it seems from reading the post that newer developments were underway, and I was wondering if I could get an updated answer to the question: is there any difference from freesurfer's perspective of using T2-space or T2-space-flair? Thank you for your help! Michelle
