Re: [Freesurfer] LGI value extraction

That is really LGI. aparcstats2table just defaults to "thickness". But you should double check that the value you see in lh.aparc_lgi.stats is the same as in result_lgi_lh.txt On 9/29/2020 12:38 PM, 祝菲 wrote: External Email - Use Caution Dear expert, I have used freesurfer v6.0 to

Re: [Freesurfer] preproc-sess - motion correction problem

I'm guessing that AFNI can't do MC on a 2d "volume" (MC is inherently a 3D operation). You can try turning off MC in preproc-sess with -nomc On 9/25/2020 11:56 AM, Nasr, Shahin,Ph.D. wrote: Hi Surfers,      I have faced an issue with preproc-sess and I appreciate your help.  I have a single

Not subcortical volume, you'll need VBM for that On 9/28/2020 7:01 PM, Zeng, Qi wrote: External Email - Use Caution Hi, Is it possible to use Freesurfer to extract global voxel-wise cortical thickness and subcortical volume? Thank you so much! Best, Qi

Dont use --trgicoorder. Also, smooth the input, not the output (ie, use --fwhm not --fwhm-trg). Don't use projfrac there (which will fix the --sval-xyz error). Your 2nd command looks the same as the first On 9/27/20 10:30 PM, 谢娆 wrote: External Email - Use Caution Hi, To begin
