External Email - Use Caution Hello John, You might be able to tell from the log what directory recon-all was cd'd into when the creation of the soft link failed.  You could try to cd there as your userid (which I assume you used to run recon-all), and see if you can manually create any soft link there.  if you cannot do so, there could be a problem with the directory permissions.  The uersid running recon-all should have permission to read, write, and execute on subdirectories which typically means the permission on them is set to be 755. While do not officially support cuda, I would first check to see you have the cuda libraries installed on you system.  You could do a search under /usr to see if you have it, e.g. $ sudo find /usr -name "libcudart*" - or with the package tools, look to see if any nvidia or cuda packages are installed,  e.g., $ rpm -qa | grep -i nvid $ rpm -qa | grep -i cuda If you don't find a libcudart.so.5 installed, then I think you will need to install rev 7.5 of the cuda tools on your system as that should be the version with libcudart.so.5 - R. John Absher June 22, 2019 at 22:28 External Email - Use Caution Hi, I am testing a new installation of freesurfer. Two errors occurred, and I'm hoping someone can help me troubleshoot: First, recon-all exits with error indicating that it is unable to create a symbolic link: [GHS\026278@vmcntdsktp10 fs_sample1]$ tail /neuro_images_isilon/026278/fs_sample1/sample001/scripts/recon-all.log ICI = 216.7, FI = 1989.1, variation=32373.324 writing Gaussian curvature to ./lh.white.preaparc.K...done. writing mean curvature to ./lh.white.preaparc.H...done. rm -f lh.white.H ln -s lh.white.preaparc.H lh.white.H Linux vmcntdsktp10 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux recon-all -s sample001 exited with ERRORS at Sat Jun 22 17:10:41 EDT 2019 To report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting The error occurs in CentOS 7 running on a virtual machine environment, with the latest stable freesurfer release, 6.0.

question for preprocessing
by ping cao 23 Jun '19

23 Jun '19

External Email - Use Caution Dear expert， Thank you for reading! I want to do these four pre-processing steps: 1. Re-sampling each MR image to 256*256*256; 2. Using the N3 algorithm for intensity inhomogeneity correction; 3. Skull stripping; 4. Removing the cerebellum. Does " *recon-all"* do all the above 4 steps automatically? If so, which file is just finished with these four steps? If not, how can I do these steps? Your help is greatly appreciated. Best, ping

WARNING: no voxels in AR1 computation
by Francesca Pentimalli 22 Jun '19

22 Jun '19

External Email - Use Caution Dear FreeSurfer experts, I am trying to run *mri_glmfit *on a series of concatenated volumes. mri_glmfit --y $SUBJECTS_DIR/concat/new_glm_input.mgh --fsgd Qdec/qdec.fsgd --mask fsaverage/label_volume/mask.mgz --glmdir glm_output --C $SUBJECTS_DIR/qdec/Untitled/contrasts/lh-Avg-Intercept-volume.mat I am getting the following : WARNING: no voxels in AR1 computation. I am guessing that this is due to the results of the analysis, or is this potentially a problem with the specific contrast used? If so, what should be kept in mind while creating new contrasts?

External Email - Use Caution Hello, I'm trying to create label files of the aparc+aseg ROIs but cannot find the aseg annotations. The ?h.aparc.annot does not contain subcortical regions that exist in the aparc+aseg.mgz volume. Is there a way to apply mri_annotation2label to aseg labels? Thanks! Best regards, Sam

Within-subject vertexwise correlation
by Matthieu Vanhoutte 22 Jun '19

22 Jun '19

External Email - Use Caution Dear FS experts, I would like to compute within-subject correlation between two modalities based on vertexwise maps in fsaverage space. I wonder whether I have to smooth the normalized surface-based maps before computing vertexwise within-subject correlation? I have noted that smoothing surface maps before computing correlation increases the output correlation value. Thanks for your lights. Best, Matthieu
