libs dependents for ''preproc-sess'' command
by Hang Zeng 11 Aug '19

11 Aug '19

External Email - Use Caution Dear Sir or Madam, I am running preproc-sess command on Linux Debian. The thing is it shows error msg like '3dvolreg.afni error while loading shares library :libXp.so.6. No such file or directory. After I installed the libXp.so.6, other lib like libpng is required. I am wondering what might be the causes, and how to fix it. If it is indeed the problem of libs, can I have a list of the dependent libraries for that command? Best regards, Zoe

CORRECTING DEFECT
by Balken, Brendan 09 Aug '19

09 Aug '19

External Email - Use Caution Hello! So I am attempting to use freesurfer's recon-all script but for one of our subjects I keep getting stuck at this point: "CORRECTING DEFECT 29 (vertices=19321, convex hull=4029, v0=32423) XL defect detected..." It has already corrected 28 defects, but they were much smaller. It has been running for about 48 hours on a very powerful machine and I'm wondering how long I should wait. Will it eventually move on? If no, what is my contingency plan for processing this? I'm using the output anatomy folder in brainstorm for source analysis. Any guidance or information would be greatly appreciated. Thanks a million! Brendan Here's what the lh and rh.inflated.nofix look like (is that the defect?): [cid:image001.png@01D54E9B.E7838030]

TRACULA - OrientLAS issue for a subject
by Daniel Callow 09 Aug '19

09 Aug '19

External Email - Use Caution Hello, I am running TRACULA on my data set and am having issues with one of my subjects. For this subject, I get the following error. INFO: input image orientation is LIS INFO: input image determinant is 18.4229 rdc_new: Undefined variable. rdc_new: Undefined variable. rdc_new: Undefined variable. ny_new: Undefined variable. I have attached the dcminfo.dat file of this subject. It seems like mri_info is having trouble either extracting or writing cdc, rdc, and sdc values from this subject's dcminfo.dat file? Any idea why this might be? I have looked through this subjects dcminfo.dat file and compared it to others but have been unable to identify the issue. I have also included the trac-all log for this subject. Some advice on what the issue might be would be greatly appreciated! *Daniel Callow* *PhD Student, Neuroscience and Cognitive Science* Exercise for Brain Health Lab University of Maryland, College Park *ddcc2442(a)gmail.com <ddcc2442(a)gmail.com>* 443-254-6298

Hippocampal subfields
by 郑凤莲 09 Aug '19

09 Aug '19

External Email - Use Caution Hi exports, I am using FS6.0 to segment hippocampus. I run "recon-all -s bert -hippocampal-subfields-T1" and it said "recon all bert finished without error". However, in mri directory, there is no l(r)h.hippoSfLabels-T1.v10.mgz file. And in tmp directory, there are two directories, "hippoSF_T1_v10_left" and "hippoSF_T1_v10_right". But in these two directories, the l(r)h.hippoSfLabels-T1.v10.mgz file is still not exsit. What's the matter? I need your help. Thanks very muxh in advance. Sincerely, Zheng

Avoiding or removing overlap when converting surface labels to volume
by Jacob Miller 08 Aug '19

08 Aug '19

External Email - Use Caution Hi Freesurfer team, I am transforming several adjacent surface labels into volume ROIs, using *mri_label2vol*. When doing so, there seems to be some possibly unavoidable overlap in a small number of voxels in the volume ROIs. Is there any way to avoid these labels from overlapping when transformed into the volume? I see that *mri_label2vol* takes an --annot flag, would this help in avoiding overlap in the outputs? Otherwise, I can remove the overlapping voxels int he nifti file outputs, but I was wondering if the algorithm had any options to do this as part of the surface-to-volume transform. Thanks so much!

TRACULA empty bbr maps after trac-all -prep
by Fred Sampedro 08 Aug '19

08 Aug '19

External Email - Use Caution Dear TRACULA experts, dear Anastasia, I've been successfully using TRACULA for a while with different DTI images from different scanners (siemens, philips...). Now I am working with GE DTI data and whereas the trac-all -prep command went well, and $subject/dmri/dtifit_FA.nii.gz and dtifit_MD.nii.gz look fine, $subject/dmri/mni/dtifit_FA.bbr.nii.gz and all mni-space maps are empty (see pictures attached). I also attach the trac-all.log file. and bvals/bvecs that were generated by trac-all directly from the dicom images. What could have gone wrong?
