bilateral seed to whole brain connectivity analysis
by Nasiriavanaki, Zahra,M.D. 10 Aug '21

10 Aug '21

Dear Experts, I have functional ROIs on the left and right hemispheres, and I’m trying to do a bilateral seed to whole brain connectivity analysis. My question is: in order to make a bilateral seed, shall I manually average the .dat files (output of fcseed-sess) from left hemi and right hemi to make a bilateral seed (see below)? fcseed-config -segid 1 -seg lh.mgz -fcname lh.dat -fsd rest -rlf restruns -mean -cfg lh.config fcseed-sess -s . -d . -cfg lh.config fcseed-config -segid 1 -seg rh.mgz -fcname rh.dat -fsd rest -rlf restruns -mean -cfg rh.config fcseed-sess -s . -d . -cfg rh.config bilateral.dat= (lh.dat+rh.dat)/2 OR should I use the left and right ROIs in fcseed-config at the same time, so the out put of fcseed-sess be the bilateral seed? Please see below commands: fcseed-config -segid 1 -seg lh.mgz -segid 1 -seg rh.mgz -fcname bi.dat -fsd rest -rlf restruns -mean -cfg bi.config fcseed-sess -s . -d . -cfg bi.config I appreciate your responses. Thanks, Mona Zahra (Mona) Nasiriavanaki, M.D. Postdoctoral Research Fellow Department of Psychiatry | MGH/HMS 149 13th Street, 149-2615 Boston, MA, USA, 02129

External Email - Use Caution fyi ---------- Forwarded message --------- From: Christopher Markiewicz <markiewicz(a)stanford.edu> Date: Mon, Aug 9, 2021 at 5:01 PM Subject: [Neuroimaging] [Nibabel] Discourse category for Surface API discussions To: neuroimaging(a)python.org <neuroimaging(a)python.org> Hi all, I'm starting to work on the Surface API portion of the Nibabel grant. I've created a category on the Discourse here: https://secure-web.cisco.com/1fZyTqmwozZU5Qoa2utEX0kDdW_8B7XIMEFga96aHR-Yct… And I've started some initial notes here mostly laying out the problem: https://secure-web.cisco.com/1qQtCe4EJSW0O7Z_CBMnNittP03bU4FYzr1xy2YZOTw_oa… The next steps are going to be to identify use cases for people working with surface data, which will also involve finding people who I may not know about, so please forward this on to people who might be interested in joining the discussion. -- Christopher J.

dwi_orig_las issue trac-all -prep in FS 7.2
by juergen.haenggi＠upd.unibe.ch 09 Aug '21

09 Aug '21

External Email - Use Caution Dear TRACULA experts I use the newest version of TRACULA (FS 7.2, official release) and face the same problem as already reported by another user https://secure-web.cisco.com/1X5AHUcHXClyJtmxIDuq0cEQ7oR9Y81XGrojDN0ZsSnvYn… As suggested by the answer to the above link, this other user did not use an official release of FS, and no explicit solution was mentioned in this link. I used an official version, but got the same error. BTW, if using TRACULA in FS 7.1.1, this error did not occur. The error that occurs is the following (log and config file attached): error: niiRead(): error opening file /Volumes/Datenspeicher/01_IPS/04_C_DTI_TRACULA/01_TRACULA_Results_NIFTI_FS720/IPS_CO_007/dmri/dwi_orig_las.nii.gz As described by the other user, the file is initially created, but then renamed to dwi.nii.gz and therefore not present in the dmri directory. BTW, my data is already in LAS orientation. The error only occurs if using NIFTI files but not if using the DICOM files. Actually, I could use DICOMs, but I faced the problem that dTE could not be found in the DICOM header and/or b0info.dat file, respectively, (see error below) because only one TE is present in the DICOM header of the phase image as suggested by the meta data in the OSIRIX DICOM viewer, and therefore I would rather use NIFTI files and define dTE in the config file as it has been suggested that this is possible in TRACULA in FS 7.2. writing to /Volumes/Datenspeicher/01_IPS/04_C_DTI_TRACULA/00_TRACULA_Results_DICOMs_FS720/IPS_CO_007/dmri/b0pha.nii.gz... mri_probedicom --i /Volumes/Datenspeicher/01_IPS/04_C_DTI_TRACULA/00_TRACULA_Prepared_DICOMs_FS720/IPS_CO_007/Phase/33163229.dcm > /Volumes/Datenspeicher/01_IPS/04_C_DTI_TRACULA/00_TRACULA_Results_DICOMs_FS720/IPS_CO_007/dmri/b0info.dat ERROR: Need dTE for field map /Volumes/Datenspeicher/01_IPS/04_C_DTI_TRACULA/00_TRACULA_Prepared_DICOMs_FS720/IPS_CO_007/Phase/33163229.dcm However, if I try to use DICOM files and "set dTE = 2.46“ in the config file, the same error occurred as when not setting dTE in the config file. Thanks in advance for any advice Best regards Jürgen

Creating an Freesurfer .annot file from an MNI coordinate region of interest
by Paul Dhami 05 Aug '21

05 Aug '21

External Email - Use Caution Dear FS community, My ultimate goal is to do a seed of interest connectivity analysis. Accordingly, I have MNI coordinates for a seed (e.g., left DLPFC). However, for the softwares I am using (CONN toolbox and Brainstorm), I need a .annot file which has the surface region of interest label I want to use as the seed. My problem is I do not know how to create an .annot file from MNI coordinates of my seed/region of interest. Can I create an .annot or label file with Freesurfer centered around an MNI coordinate, or would I first need to create a volume ROI using another software? Any directions as to how I can do this would be greatly appreciated. Best Wishes, Paul
