Re: [Freesurfer] number of vertices

do you mean of one of the surfaces derived from the image? If so, you can use mris_euler_numer or mris_info cheers Bruce On Wed, 22 May 2019, Sam W. wrote: External Email - Use Caution Hi, How can I check how many vertices an image of my subject has? Best regards, Sam

mris_info lh.orig will do it On 5/21/2019 6:45 PM, Sam W. wrote: External Email - Use Caution Hi, How can I check how many vertices an image of my subject has? Best regards, Sam ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu

Thanks! That number helps. Just want to get an approx. number in general. Best, Daniel -- Daniel Yang, Ph.D. Yale Child Study Center E-mail: daniel.yj.y...@yale.edu On 2/29/16, 11:52 AM, "freesurfer-boun...@nmr.mgh.harvard.edu on behalf of Bruce Fischl" wrote: >it's usually a bit less tha

it's usually a bit less than that - aroudn 140K or so Bruce On Mon, 29 Feb 2016, Yang, Daniel wrote: > Hi Bruce, > > Is it okay to say that it is approximately 160,000 vertices per > hemisphere? I found the answer from a paper > (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3824100/pdf/fnhum-07-0

[Freesurfer] number of vertices

Dear FreeSurfer experts, Can you please indicate the number of vertices FreeSurfer use in each hemisphere to reconstruct the brain (e.g., cortical thickness)? Is there a fixed number or an approx. number? Many thanks, Daniel -- Daniel Yang, Ph.D. Yale Child Study Center E-mail: daniel.yj.y...@

Re: [Freesurfer] number of vertices

Hi Bruce, Is it okay to say that it is approximately 160,000 vertices per hemisphere? I found the answer from a paper (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3824100/pdf/fnhum-07-00722.pdf ). Best, Daniel -- Daniel Yang, Ph.D. Yale Child Study Center E-mail: daniel.yj.y...@yale.edu On

Re: [Freesurfer] number of vertices

Hi Daniel the number of vertices will vary depending on the surface area and geometry of the white matter for each hemisphere. cheers Bruce On Mon, 29 Feb 2016, Yang, Daniel wrote: Dear FreeSurfer experts, Can you please indicate the number of vertices FreeSurfer use in each hemisphere t

Re: [Freesurfer] number of vertices per hemisphere using mri_glmfit

If you do: $>mris_calc stats the first line reported back will be the number of vertices. So, if you want to know how many vertices on the left hemisphere: $>mris_calc lh.thickness stats and look at the Size[ XXX ] where XX will be number of vertices. Stefan Brauns wrote: > Hi

Re: [Freesurfer] number of vertices per hemisphere using mri_glmfit

usually around 140k/hemi. If you make a label and save it as a label file it will have 1 line/vertex On Tue, 19 Jan 2010, Stefan Brauns wrote: > Hi there, > > I am running surface based analysis of cortical thickness using FreeSurfer. > Sometimes I constrain the analysis to certain regions of t

Re: [Freesurfer] number of vertices per hemisphere using mri_glmfit

In the mri_glmfit.log file, there is a "SearchSpace" this will be in mm2 for surfaces and mm3 for vols. There will also be a mask.mgh file. You can run mri_segstats on this to give you the number of elements that are == 1. doug Stefan Brauns wrote: > Hi there, > > I am running surface based an

[Freesurfer] number of vertices per hemisphere using mri_glmfit

Hi there, I am running surface based analysis of cortical thickness using FreeSurfer. Sometimes I constrain the analysis to certain regions of the brain, e.g. only frontal lobes. I would like to find out how many vertices per hemisphere are analysed with the mri_glmfit I am running. Is there a pos
