Scan sequences and parameters in hippocampus segmentation.
by Qin weiting 30 Dec '17

30 Dec '17

Dear FreeSurfer experts, I'm sorry that English is not my mother language. I have met some trouble in choosing the scan sequences and parameters of data collecting in hippocampus segmentation, I have read the MORPHOMETRY PROTOCOLS on FreeSurfer Wiki, but our lab only has GE Discovery MR 750W instead of Siemens MRI. How should the T1 and T2 scan sequences and parameters be designed on a GE MR 750W? Thank you very much！ Best, Qin weiting

skull strip / pial issues on many scans
by Michelle VanTieghem 30 Dec '17

30 Dec '17

Hi Douglas, I am not sure why my previous message (posted Dec 22) did not get posted. I have reported many problems with the skull stripping and resulting issues in freesurfer. To summarize: 1. For our structural scans, we have significant pial matter/dura matter remaining for > 50% of subjects or more (of a dataset of 350 scans). I have tested using freesurfer's gcut and other options, as well as AFNI skull strip, FSL with many options, and even ANTS. 2. We gave up on trying to use surfaces with this dataset, due to the sheer amount of manual intervention that would be needed to edit the brains. A colleague suggested that Freesurfer v 6 may work better than 5.3 , which we had been using. Do you think that would make sense? 3. The aseg almost always labels the remaining skull as gray matter, which then influences the icv and wbv measurements. 4. Recently we have decided to try the longitudinal pipeline. Another problem appears: if a cross-sectional scan does not have any pial matter (as in, it is one of the few that as successfully skull stripped - we call these the "clean" scans) but a template is made from multiple scans from this subject. If one of those other tp scans from this subject has any pial mater remaining, then the (a) the template will include all of the pial matter and (b) the longitudinal version of the "clean" scan now has extra pial matter that gets erroneously labeled as gray matter, or sometimes white matter. I have been trying to solve this for over a year, and I also sent data to freesurfer over the ftp on December 1st using the directions on the freesurfer wiki, if you want to take a look at a single representative scan with this skull strip issue. Thanks! Michelle -- Michelle VanTieghem PhD student in Psychology Developmental Affective Neuroscience Lab Columbia University mrv2115(a)columbia.edu

mri_glmfit-sim and Ftest
by Pauline Duret 29 Dec '17

29 Dec '17

Hi Freesurfer experts! I know we asked this question before, but maybe someone came back from holidays and know the answer! Does Hi Freesurfer experts. Does mri_glmfit-sim Monte-Carlo cluster size correction is also usable for F-test? The doc says that it synthesizes a z map (I assume from a normal distribution) for computing the voxel-wise thresholds and cluster size distribution. Maybe I am wrong with my stats but I wonder if it is ok to use this null-hypothesis to a F-distributed data such as results from a F-test. Thanks! Monte-Carlo cluster size correction is also usable for F-test? (When doing a 3-groups comparison and testing the effect of group on lGI). The doc says that it synthesizes a z map (I assume from a normal distribution) for computing the voxel-wise thresholds and cluster size distribution. Maybe I am wrong with my stats but I wonder if it is ok to use this null-hypothesis to a F-distributed data such as results from a F-test. Thanks so much!

Question about an error during recon-all process
by 박경일 28 Dec '17

28 Dec '17

Dear experts, I am sorry for asking again. I have some problems in running recon-all. Recon-all process was shut down with this error message ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0000, pval=0.0000 < threshold=0.0050) Manual Talairach alignment may be necessary, or include the -notal-check flag to skip this test, making sure the -notal-check flag follows -all or -autorecon1 in the command string." I guess this is because of low resolution or small size of images. is it right? Thank you so much for you help in advance. FYI, log file is attached. Kyung

bbregister error -- Human Connectome Project Data
by Lana Ruck 28 Dec '17

28 Dec '17

Hello, I am currently starting a project with the minimally pre-processed rfMRI from the Human Connectome Project, but I need to do some additional processing first. This includes smoothing at 6mm FWHM and projection onto the fsaverage4 surface. I have smoothed the pre-processed rfMRI data using mri_convert (and have also converted the provided brain-extracted anatomical), but I am having issues registering the smoothed rfMRI volumes, and I understand that I need these register.dat files for mri_vol2surf. I have tried bbregister --init-fsl; bbregister --init-spm; and manual registration using tkregister2. All of them give me the same error--I think it is a path error looking for a subject-specific brain mask (see detailed console errors below). After reading through others' problems with bbregister, I made sure I am running the updated versions of bb- and fsl-register, below: fslregister,v 1.40 2016/02/12 21:43:15 zkaufman bbregister,v 1.75 2016/05/10 20:02:28 greve freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c I also made sure these files had the edits recommended to others, so I don't think this is an previously-addressed issue. That // in all my errors suggests to me that this is a path problem with my HCP data? I am new to FreeSurfer, but I would think that the HCP-pre-determined path organization should be compatible with FSL and FreeSurfer, since their pipelines use both. Is this a compatibility issue with FreeSurfer 6.0? Anyways, I would prefer to use bbregister --init-fsl, but do not know how to point it to the right directory for a brainmask. There is no information provided in any of the --help menus or Wiki pages regarding how to specify brain masks for registration, and the HCP pre-processed data provides multiple 'mask.nii.gz' files that I suppose are not being recognized by bbregister (perhaps because they are not .mgz? I tried converting one to mgz and also got an error from mghWrite). Either way, I have 4 rfMRI runs per subject and over 40 subjects to process, so any advice on this error would be greatly appreciated. Thanks in advance!

Re: [Freesurfer] FreeSurfer recon-all issue

Dear Shadia, There are 2 spots in recon-all where symbolic link is created. The first you can overcome by: find following line in your recon-all: set cmd2 = (ln -s $hemi.white.preaparc.$suffix $hemi.white.$suffix) and replace it by set cmd2 = (cp $hemi.white.preaparc.$suffix $hemi.white.$suffix) The second you overcome by copying the directory $FREESURFER_HOME/subjects/fsaverage and all its contents of to your $SUBJECTS_DIR. Then rerun recon-all on your subject.

Hello, I chose comment out the set bvecfile, bvallist, bvalfile fromt the design script. >From my understanding those variable above are not needed if we have a proper DICOM. All my subjects ran without error, but, How can I confirm that my DICOM version is compatible wtih tracula, How do I know the gradient tables are being read from the DICOM correctly? Thanks so much, Joseph
