Freeview volume measurements on newly created VOIs
by Kim, Jisoo,M.D. 14 Nov '18

14 Nov '18

Hello Freesurfer developers, I am trying to get volume measurements (mm^3) on VOIs (volume of interest) that I created on Freeview. All I can do is to export the VOI as an .mgz file. Do you know of an easy way to get the stats in .txt or any other formats? 1) Freesurfer version: freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c 2) OS: MacOS Sierra Thank you very much. Best, Jisoo

aparc table multiple comparisons
by Ralf Veit 14 Nov '18

14 Nov '18

External Email - Use Caution Dear list members, I run mri_glmfit using the aparc stats tables as input and I got a sig.table.dat file with -log10(p-values) for each ROI and contrast. Are the p-values already corrected for multiple comparisons? If not, what do I have to do in order to get corrected p-values (using aparc stats file as input).

co-registration between slab of DTI image
by Yixin Ma 14 Nov '18

14 Nov '18

External Email - Use Caution Hi Freesurfer experts, I'm writing to ask about coregistration between a thin oblique coronal slab of DTI image ( only 15 slices) and a cubic 1x1x1 voxel size anatomical image (volume size is 256x256x256), with additional whole brain low-resolution DTI to assist registration. The codes I use are as attached: I have few concerns: 1) the input oblique coronal slab of DWI image does not have header information, should it be better if I input the DWI slab in RAS coordinates (axial volume)? 2) Should I zero-fill the DWI slab to match the volume of T1.mgz? I already did that because it won't start to calculate the cost function between the thin DWI slab and anatomical image if I don't zero-fill. However, I feel like the cost function cannot make sense of the fact that the zeros are already outside the region of interest. 3) Should I use --init-fsl /--init-spm in this case? Neither of these two worked. Is there a better optimization function recommended? I have been using fsl flirt function 2 step registration (from DWI slab to whole brain DWI; From whole brain DWI to whole brain anatomical image) to do the registration. But I don't think it's the best way. For freesurfer bbregister, I have been trying to change things here and there, but the co-registration does not work well. Do you suggest to look at any parameter particularly based on this scenario? Thank you for your help, Yixin Note that isoDWI111_256_axial.nii is the slab of DWI image EPI_iso111_256_axial.nii is the whole brain DWI image [The freesurfer reconstruction is performed before all these] bbregister --s 30426 --mov isoDWI111_256_axial.nii --*int* EPI_iso111_256_axial.nii --init-fsl --reg xform_freesurfer.dat --dti tkregister2 --reg xform_freesurfer.dat --mov isoDWI111_axial.nii mri_vol2vol --reg xform_freesurfer.dat --mov isoDWI111_axial.nii --fstarg --o isoDWI111-*in*-anat.mgh mri_convert isoDWI111-*in*-anat.mgh isoDWI111_reg.nii

MRISalloc
by Chris Petty 14 Nov '18

External Email - Use Caution I’ve tried processing a healthy brain through v6.0.0 and _dev versions only to get hung at this step in each of the versions. The brain looks normal. I’ve tried adjusting the skull strip and using control points in a location that the brain was not found correctly, but it always stops at this exact step. I’ve tried processing with the RAW data as well has HCP preprocessed anatomicals. Any insight into this error? Is this some sort of convoluted memory error?

Questions on ApplyMorph of electrodes coordinates to a common template
by Liu, Feng 14 Nov '18

14 Nov '18

Dear freesurfer users, I have a problem regarding to how to map the electrode coordinates to a common template. After running mri_cvs_register, I got a cvs subfolder, and then I run applyMorph --template /autofs/cluster/freesurfer/centos7_x86_64/dev/subjects/cvs_avg35_inMNI152/mri/orig.mgz --transform $SUBJECTS_DIR/$subid/cvs/combined_tocvs_avg35_inMNI152_elreg_aseg.tm3d point_list $SUBJECTS_DIR/$subid/cvs/coord_xyz.txt $SUBJECTS_DIR/$subid/cvs/transformed_coord.txt linear where coord_xyz.txt contains all the original coordinates information, but after that I did a visualization using freeview, and the transformed coordinates looks outside of the brain. Anyone knows how to fix this problem? Or what is the cause of this problem. The original RAS coordinates align well for the brain of each subject. I searched a lot of email archives, but didn't find a good answer. Thanks. Best regards, Feng [cid:1b19e3e7-51a7-4abb-afdb-c81cb9adc99e]

External Email - Use Caution Dear colleagues, 2PhD and 1 post-doc positions are available at my group, University of Lausanne, Switzerland. The positions are funded for 4 years (with annual contract renew) by the Swiss National Science Foundation grant. Ideally starting on January 2019 but this can be adapted. Briefly we look for the following profiles: 1 post-doc: versatile both in MRI physics/sequence programming and image processing, dedicated to the development of MR sequences aimed at quantitative T1 and T2 mapping of the fetal brain. 2 PhD thesis: (i) the development machine learning segmentation methods for the fetal brain analysis and their integration to a joint segmentation-super-resolution reconstruction of T2-weighted and T2 quantitative images of the fetal brain. (ii) the development of an image processing pipeline for the super-resolution reconstruction of diffusion fetal brain MRI, including the exploration of new acquisition schemes on phantom data. Details of the project and profiles are attached. For more information please contact Dr. Meritxell Bach Cuadra (meritxell.bachcuadra(a)unil.ch) Best regards, Meritxell Bach Cuadra

Improving skull stripping - Need help
by Rosalia Dacosta Aguayo 14 Nov '18

14 Nov '18

External Email - Use Caution Dear FreeSurfer team, In order to improve the skull stripping for some of the participants of the sample, I replaced the brainmask.mgz generated in FreeSurfer by the betted image generated from FSL, and I run recon-all again. The problem is that, again, FreeSurfer generated again another brainmask without saving my brainmask and now, I have, again, a bad skull stripped image. Any help with this would be greatly appreciated. Best regards, Rosalia
