[Freesurfer] mri_glmfit-sim cluster correction threshold inquiry

External Email - Use Caution Hello, I am planning on running a correction for multiple comparisons, and I was hoping to use a vertex wise cluster forming threshold of 1.3, however after reading more when I ran the mri_glmfit-sim —help command it recommends using the

Is that point labeled as WM in the aseg? If so, then it is not a problem with matlab:) On 3/7/19 5:58 PM, Sparsh Jain wrote: > > External Email - Use Caution > > Thanks a lot! It worked. > While most of the labels were correct, the matlab script returned the > wrong location for one

Can you include the previous emails so we have context? On 3/7/19 6:16 PM, Sparsh Jain wrote: > > External Email - Use Caution > > Good evening. >  Thanks a lot for the help. It worked ! > While most of the labels were correct, the matlab script returned the > wrong location for one

Re: [Freesurfer] projfrac question

Can you try it again? this time use -projfrac 0.2 pf020  (ie, add "pf020" after 0.2). Then when you use mkanalysis-sesss, add -expkey pf020 to the command line. The pf020 will be included in the output file name to make it unique. This allows you to use a single project folder (ie, you don't

Re: [Freesurfer] regions of Yeo 17 networks in fast

You have to convert the annotation to a volume using mri_aparc2aseg (look at recon-all.log for an example, but note that you'll need to specify the output so that it does not overwrite). You'll then need to look in the output segmentation and see what the segmentation ids are On 3/7/19 4:13

Re: [Freesurfer] Accounting for family relation in FS

Sorry for the delay ... This looks like a fairly complicated design, and I'm not sure how to think about it. What do you actually want to test in the end? BTW, the FSGD file you have there will not work. The variables are for continuous variables (eg, age) and not discrete variables (eg, sex
