Dear Freesurfer community,
I obtained score matrices of surfaces after performing diffusion embedding
map on fMRI data.
I am now using the SurfStat toolbox(Matlab) in order to obtain p-value maps
to compare between two groups.
After obtaining the p-v

I have run my data through the longitudinal pipeline. I would like to

Thank you for your swift response as always, may I know how to convert the more

Hi!
Unfortunately, it turns out that downgrading glibc does not solve this
issue, neither with .14 nor with .15 versions.
Doug, we are calling mri_convert from a csh script, with the following
options:

Hi Loic
if you are on the fsaverage surface you can save the -log10(p) values
using save_mgh.m, then load them in freeview and threshold them or
whatever

Hi Mustafa
I believe I did:
mri_convert -it dicom IMAGE001 mprage.mgz
recon-all -i mprage.mgz -sd -s -all
you can give it any *single* image in the correct series (don't give it
more than one)
cheers

Hi Victor
the lh.white.{KH} are generated from the lh.white file, so I don't think
it can have skipped creating it. Was it deleted? Can you double check?

Thanks for your response. Is it also fine for fsaverage5 surface or I need

Hi Freesurfer experts
I am making an analysis in Freesurfer version 6 and I have a question about the
"refeventdur" in mkanalysis-sess command.
My stimulus duration is 16 seconds, but for a specific analysis, I only want to
include half of the stimulus duration (ex: the first 8 seconds only OR
No, you'll need to change your paradigm file to have two distinct 8 sec
events rather than one 16 sec event.

Your attachment says that none of the commands could be found. Make sure
you set up your environment correctly

They should be there. Can you send recon-all.log and conf2hires.log files?

Dear Freesurfers,
I am trying to obtain clusters of vertices whit a certain value over a
threshold inside a lesion mask projected to the surface, with the command:
mri_surfcluster --subject MS075_R01_07_R1year --hemi lh --in
lh.MS075_R01_07_R1year.subjspace.mgh --surf lh.pial --mask
lh.surf_m
How did you choose thresholds of 1 and 49.95? In general, you don't need
to set --thmax. If you input is a binary mask, then you should set
--thmin to somethiing below 1 (eg, 0.5)

I want to extract clusters within the cortical lesion mask in which the vertex
values are below 49.95
The values are in the file lh.MS075_R01_07_R1year.subjspace.mgh

You will not need to run the entire stream again. Did you run it in
high-res mode? If the volumes are conformed (eg, orig.mgz is 1mm,
252^3), then you do not need to do anything. Otherwise, you will need to
re-run only part of it using the patch and running
recon-all -s subject -segstats -parcs
When you look at the overlay in freeview and set the min thresh to 1, do
you see blobs?

And what about the mask? Display the mask in freeview at a threshold of 0.5

Hello Caspar,
So are you saying that if you run directly from the terminal in bash (or maybe
in csh with % sign as prompt)
