mri_aparc2aseg: how to remove redundant output labels?
by Ellen Ji 03 Aug '20

03 Aug '20

External Email - Use Caution Dear experts, I am running mri_aparc2aseg using two annotations as input (one for each hemisphere), each with 159 labels, and wish to end up with a single output segmentation of 318 labels. However, when I run the below, this is not the case: mri_aparc2aseg \ --s subject1 \ --annot 500_sym.aparc \ --wmparc-dmax 2 \ --labelwm \ --hypo-as-wm \ --o subject1/mri/parcellation.nii.gz In fact, the output has 680 labels rather than 318 labels. A few questions. - How can I see what exactly the 680 label names are (how to extract from the .nii.gz output file)? Currently, I have just quantified it to be 680 by doing this in matlab: gunzip('parcellation.nii.gz') a = MRIread('parcellation.nii'); u = unique(a.vol(:)); length(u) % total number of labels - I believe the extra labels are from the Freesurfer LUT. How can I make sure they are not added when running mri_aparc2aseg? (such that only my annotation labels are included in the output) Thank you very much, Ellen ***** Ellen Ji, PhD Postdoctoral Research Fellow Psychiatric University Hospital University of Zürich ellen.ji(a)bli.uzh.ch homanlab.github.io/ellen/

Gray matter volume image per group
by Oana Georgiana Rus 03 Aug '20

03 Aug '20

External Email - Use Caution Dear Freesurfer Community, I want to have an image of the average gray matter Volume in each of my 3 groups, and I did not find a good way to do it. I easily obtained an image from the GM thickness and area by using make_average_subject in each of my 3 groups (young musicians, old musicians and old nonmusicians). Thereby in the surf subfolder I could find an image of these 2 measures. Could anybody give some helpful hint. I am using FreeSurfer 6.0 on an Ubuntu Machine.18.04.4 LTS. Best regards, Georgiana

Maintain consistency in build stamp patterns
by Billah, Tashrif 31 Jul '20

31 Jul '20

See the build stamp patterns: In versions < 6.0.0: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c In version 7.1.0: freesurfer-linux-centos7_x86_64-7.1.0-20200511-813297b The latter has "v" missing from the version string that makes it hard for my pipeline to detect FreeSurfer version. Can you include that in future releases? Also, it would help if you can have a VERSION.txt file with just version string in it such as 7.1.0. -Tashrif .

In my MRI scans freesurfer includes areas to the white matter, even though visual inspection concludes that the area should be grey matter. Is there a possibility to change the value at which freesurfer includes areas to the WM, which i can just change? For example freesurfer includes areas to the WM with intensity values below 85 and i want to change that. I'd be thankful for any feedback/links to guides.

Recon-all Soft Errors
by Elana Sarabin 30 Jul '20

30 Jul '20

External Email - Use Caution Hi Freesurfer experts, I am a first time user of FreeSurfer and I haven’t been able to find any threads for how to fix some of my problems. I have a very large dataset and as I am editing on freeview I am noticing that ½ or more of my participants have a large area missing in the brainmask.mgz file but the region is visible from the T1.file. In some participant scans the areas missing arent too big however other scans (the photo I attached) have a very large portion of the brain missing. I have tried quite a few things to fix this including re running recon-all, adding control points, and adjusting the wsthresh value, however, none have worked. Wondering if there is a way to fix this kind of error and if there is a way to prevent this from happening as I run recon-all on future participants. In addition, I have been duplicating my files before editing in order to always have the original files as a backup. With some participants when I duplicate the files their T1.mgz file ends up completely white (image attached). I have yet to see this in a none duplicated file however with some participants I can duplicate the files and have no issue. I have attached photos of both of my problems. Any suggestions for fixes would be greatly appreciated. Thanks, Elana

Creating .annot file for a mri_decimate downsampeld version of pial surface
by Donelson Berger 30 Jul '20

30 Jul '20

External Email - Use Caution Hello FreeSurfer Expert, I've run into a problem that I just can't seem to solve. After downsampling teh ?.pial surfaces using mri_decimate to 20,000 surfaces and 10,002 points, I don't know how to create .annot files for the new surfaces I created. I want to be able to tell which ROI each vertex is in for my new surface based off a parcellation. I've been trying to use mri_ca_label, mri_ca_train, and mris_sample_parc, but I can't seem to get anything to work. Do you have any suggestions? Thanks for your help, Donelson Graham Berger

overlapping/ superimposing regions of one analysis over another
by Sunil Khokhar 30 Jul '20

30 Jul '20

External Email - Use Caution Dear Experts, I have done a between group (2 groups) difference in whole brain voxel based cortical thickness using QDEC, which showed significant regional differences in certain clusters bilaterally in the brain. I also did a correlation between cortical thickness and behavioral scores separately in these two groups. Now, I want to superimpose regions (clusters) which showed positive and negative correlation on the results/ regions I obtained in my between group analysis. How can I do this? Thanks in advance!
