Mri Convert Bruker MGRE files dicom to nii error
by Mateo Jean 28 Apr '22

28 Apr '22

External Email - Use Caution Hello FreeSurfer Developers I hope i don't spam, if anyone has a clue... I need to convert 512 dicom files from Bruker into .nii . I firstly add .dcm to my Bruker multi gradient echo phase files then enter the following command : mri_convert MRIm001.dcm phaseMGE.nii Here is the first message : reading from MRIm001.dcm... Starting DICOMRead2() dcmfile = /mnt/c/Users/Sahadatou/Documents/Stage_JEAN_2022/data/fantomes/tests/bug_test2/MRIm001.dcm dcmdir = /mnt/c/Users/Sahadatou/Documents/Stage_JEAN_2022/data/fantomes/tests/bug_test2 ERROR: don't know how to get DWI parameters from --Bruker BioSpin MRI GmbH -- ERROR: GetDICOMInfo(): dcmGetDWIParams() 1 DICOM File: /mnt/c/Users/Sahadatou/Documents/Stage_JEAN_2022/data/fantomes/tests/bug_test2/MRIm001.dcm break /home/rd521/space_freesurfer/build/docker_ubuntu18/trunk/rd521-7.2.0/utils/DICOMRead.cpp:4930 Ref Series No = 4 Found 514 files, checking for dicoms ERROR: don't know how to get DWI parameters from --Bruker BioSpin MRI GmbH -- ERROR: GetDICOMInfo(): dcmGetDWIParams() 1 DICOM File: /mnt/c/Users/Sahadatou/Documents/Stage_JEAN_2022/data/fantomes/tests/bug_test2/MRIm001.dcm break /home/rd521/space_freesurfer/build/docker_ubuntu18/trunk/rd521-7.2.0/utils/DICOMRead.cpp:4930 ERROR: don't know how to get DWI parameters from --Bruker BioSpin MRI GmbH -- ERROR: GetDICOMInfo(): dcmGetDWIParams() 1 Then 508 error messages like the three last lines appear. It ends with : First Sorting Computing Slice Direction Vs: 0 0 1 Vs: 0 0 1 Second Sorting IsDWI = 0, IsPhilipsDWI = 0 Counting frames nframes = 8 nslices = 63 ndcmfiles = 508 ERROR: the number of frames * number of slices does not equal the number of dicom files. I did a test with only 448 files (I just copy-paste the first 448 files = 7 TE * 64 slices) and I obtained the same error messages but the nifti files are created and seem usable (quick test with Fiji). Here are the last lines : First Sorting Computing Slice Direction Vs: 0 0 1 Vs: 0 0 1 Second Sorting IsDWI = 1, IsPhilipsDWI = 0 Counting frames nframes = 7 nslices = 64 ndcmfiles = 448 INFO: rescale not needed PE Dir = COL (dicom read) Loading pixel data TR=50.00, TE=3.10, TI=0.00, flip angle=15.00 i_ras = (-1, -0, 0) j_ras = (-0, -1, 0) k_ras = (-0, -0, 1) writing to phaseMGR.nii... Saving bvals and bvecs I'm pretty new with mri convert and I don't understand why it stops converting to nii with 512 files (8 TE) but not 448 files for Brucker files.

Cortical depth at each cortical voxel
by Fotiadis, Panagiotis 28 Apr '22

28 Apr '22

External Email - Use Caution Hi FS experts, I was wondering whether there was a way to assign each cortical voxel within the T1w (volumetric) scan an index corresponding to its “cortical depth.” I have essentially taken the cortical ribbon .mgz file, assigned each cortical voxel a voxel ID, and wanted to associate each ID with its corresponding cortical depth. I would normally use the *h.sulc files but I didn’t think this would properly translate here since it’s a volumetric analysis. Thank you in advance for your time and help!

Re: [Freesurfer] recon-all error
by Huang, Yujing 27 Apr '22

Hi Rebecca, I’m trying to get more information to determine how it core dumped. 1. Can you confirm that you are running Freesurfer 6.0? 2. From which directory, did you run recon-all and dcmunpack? 3. Can you try dcmunpack by passing it full path to dicom directory? Thanks.

I have used the original dicom files in the recon-all using the command below. Command: recon-all -s 1003156_dicom -i 2008-11-13_GE_001910/13.39_-_PACE/Ax_3D_512x256/002/I.001 -all Error message: /Applications/freesurfer_v6/bin/mri_convert: line 3: 8196 Segmentation fault: 11 mri_convert.bin "$@" The recon-all.log is also attached. I’ve also explored using dcmunpack and obtain the following result: Command: dcmunpack -src 2008-11-13_GE_001910/13.39_-_PACE/Ax_3D_512x256 Message: cat: /tmp/dcmdir-all.89439: No such file or directory Found 0 unique series: Patient: Undefined variable. Do you have any idea what might be the problem? Freesurfer version: freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c Platform: Mac OS X 10.13.3 Recon-all.log: attached.
