About mri_vol2surf

External Email - Use Caution Hello everyone, I tried to follow your instruction about how to get the fresurfer stats in AAL ROIs. I have an image .nii with the labels of the AAL in the MNI space (i submit this image in the e-mail). Can I use this image in the mri_vol2surf? If so, i suppose that this image would be the input one, but i don't know what is registration file in the syntax of mri_vol2surf Sorry for the inconvenience, Alberto

Recon-all error
by Courtney Haswell 02 Dec '20

02 Dec '20

External Email - Use Caution I am trying to debug why all of our T1's are failing Freesurfer recon-all. It seems that most of the files are being created but it isn't getting to the stats steps to output those files. In the recon-all log it does say "recon-all -s 13265 exited with ERRORS." I looked in the recon-all.error file and the only thing in that is "CMD mris_sphere -q -seed 1234 ../surf/rh.inflated.nofix ../surf/rh.qsphere.nofix." Would this be the step where the error is happening? I have checked the T1 thoroughly and it is good quality. What is the best way to debug why this is happening with our scans?

We generally fix these with T2 or FLASH scans at the same resolution/geometry/readout as the T1. Otherwise they are pretty tough as the dura is close enough to the gray matter that you can?t see any space between them Cheers Bruce From: freesurfer-bounces(a)nmr.mgh.harvard.edu <freesurfer-bounces(a)nmr.mgh.harvard.edu> On Behalf Of LIN, Yezhe Sent: Monday, November 30, 2020 5:10 PM To: freesurfer <freesurfer(a)nmr.mgh.harvard.edu> Subject: [Freesurfer] Freesurfer skullstripping error         External Email - Use Caution Dear Freesurfer users, Hope this finds you well. I preprocessed our dataset with recon-all <subj> -s <subj> -all -qcache and found a number of our subjects had different levels of skullstrip errors. I tried fixing them by a couple of different approaches, such as -gcut and adjusted watershed threshold, but they both failed to fix the overlapping of dura mater (Fig1 and 2). I tried two methods on different subjects and received the same outcome. I wonder if you have any ideas to fix this error. At this point, for some who had less skullstripping, I can erase them manually and run -autorecon-pial or -make. But for the others with multiple locations of skullstripping (like Fig 3 and 4), do you have any ideas on how to approach to them at a systemic level? Also I found the skullstripping error in over half of our subjects, is it normal that we have a such proportion?

For this reason, I would not use #1. #2 is fine.You can apply your label in fsaverage space to the y.mgh used as input to mri_segstats specifying the label using --slabel and using --avgwf output and also use --accumulate; run it with --help for more info. This will create a text file of the areas or volumes (depending upon which y.mgh you input) all your subjects for that label.

At this point, for some who had less skullstripping, I can erase them manually and run -autorecon-pial or -make. But for the others with multiple locations of skullstripping (like Fig 3 and 4), do you have any ideas on how to approach to them at a systemic level? Also I found the skullstripping error in over half of our subjects, is it normal that we have a such proportion? ?

Freesurfer skullstripping error
by LIN, Yezhe 30 Nov '20

30 Nov '20

External Email - Use Caution Dear Freesurfer users, Hope this finds you well. I preprocessed our dataset with recon-all <subj> -s <subj> -all -qcache and found a number of our subjects had different levels of skullstrip errors. I tried fixing them by a couple of different approaches, such as -gcut and adjusted watershed threshold, but they both failed to fix the overlapping of dura mater (Fig1 and 2). I tried two methods on different subjects and received the same outcome. I wonder if you have any ideas to fix this error. At this point, for some who had less skullstripping, I can erase them manually and run -autorecon-pial or -make. But for the others with multiple locations of skullstripping (like Fig 3 and 4), do you have any ideas on how to approach to them at a systemic level? Also I found the skullstripping error in over half of our subjects, is it normal that we have a such proportion?

Re: [Freesurfer] arguments to use after pial edits

arguments to use after pial edits {Disarmed}
by Darko Komnenić 30 Nov '20

30 Nov '20

External Email - Use Caution Dear Freesurfer experts, I am using Human Connectone Project pipelines to calculate cortical myelin levels. These pipelines use Freesurfer 6. Since certain subjects' brain surfaces had some chunks and spikes sticking out, I edited the brainmask.mgz file for those subjects as described in this tutorial. https://secure-web.cisco.com/134OA5xpyRuAJ4raLibeAZDGkJ8VFvtiCm69m7hXhYD442… To get the myelin maps again, I got the instruction from the HCP mailing list that I should call again the FreeSurferPipeline script, but add the --existing-subject and --extra-reconall-arg flags. If I understood correctly, after --extra-reconall-arg flag, there should be an equal sign, and then keywords that specify which recon-all stages I want to run. Could you please tell me what those stages are, i.e. what keywords I should use after the equal sign? I want to keep the brainmask.mgz file that I edited, and then repeat all the steps that happen after braimask.mgz is generated. I was referred to the FS tutorials/wiki at the HCP mailing list, but I would like to double-check with someone here. Based on the tutorial link above, it seems this should be "-autorecon-pial -subjid pial_edits_before", but I'm not sure if this would be applicable in this case. Thanks in advance and I hope my question wasn't too confusing. Best, Darko

Sources Sought: Octave/MATLAB programmer {Disarmed}
by Anderson M. Winkler 30 Nov '20

30 Nov '20

External Email - Use Caution Dear all, The NIMH/NIH is looking for a skilled Octave/MATLAB programmer, with knowledge of multivariate statistics, to implement inference for canonical correlation analysis (CCA) using permutations, as described in the recent paper (https://secure-web.cisco.com/1OvbxEv9_JHQute8AUV1-CRpI494R210wv39uPXMnlrig7…) together with other features that have already been published and which are part of PALM, as described in the "Sources Sought" notice linked below: https://secure-web.cisco.com/1fHXlDSQEyeCMPT25xy9Gg_S11v-upDxypVxM2AtRSYwhk… Note: - The search is open to persons or businesses. - The search is not limited to US citizens or to vendors based in the US. - The prospective vendor must have a Data Universal Numbering System (DUNS) number and an NATO Commercial and Government Entity Code (NCAGE code). - The prospective vendor must have either a Social Security Number (SSN) or a Tax Identification Number (TIN). - This is not employment or scholarship, but provision of a specific service to the US government. Please, read thoroughly the Sources Sought page in the link above. If you have availability and capability to perform this potential requirement, please contact Mr. Thien Nguyen (thien.nguyen2(a)nih.gov, +1-301-827-0914). All the best, Anderson

Multiple regression analysis
by Marina Fernández 30 Nov '20

30 Nov '20

External Email - Use Caution Dear all, I am doing a multiple regression analysis with 3 covariates of interest. I know that for testing two-way and three-way interactions I must create new variables by multiplying the covariates of interest. As Freesurfer transforms continuous variables to z score before applying statistic, is it correct to transform to z score the result of the previous multiplication? I am asking this because the result of multiplying two z transformed variables would be different. Thanks a lot in advance. Marina
