[Freesurfer] Pial surface running into white surface

2018-05-15 Thread Kevin Aquino
External Email - Use Caution

Hi free surfer mailing list!

I am having a problem with some subjects where the pial surface is running
into the white surface (and terminating at some points terminating within
white matter). Apologies if the solution is in the mailing list (all I
could find is that this could be fixed with FS v6). The build stamp is:

freesurfer-Linux-centos6_x86_64-dev-20170915-

what kind of edits should I be doing?

I have added the necessary files to https://github.com/KevinAquino/errorPial
if you could be so kind to have a look!

[Freesurfer] Fixed effects fMRI {Disarmed}

2017-10-09 Thread Kevin Aquino
Hi all,

I would like to perform a fixed effects analysis on a small sample of
subjects with FS-fast -- where the time series from all subjects are
concatenated together and analysed in a large design matrix.

Is there an easy way to do this? I don't know if I'm looking in the wrong
place but I can't seem to find it.

Re: [Freesurfer] FS-FAST outputs is X.mat used? {Disarmed}

2017-08-16 Thread Kevin Aquino
Thanks for that Doug,

[I was hoping i could do the parametric modulation in the contrast weights
-- SPM style of doing this after the betas were fit].

Regarding the X.mat question, sorry I wasn't clear. I can see it has the
nuisance regressors and constant terms, but is that x.mat used to estimate
the betas?

In the beta estimation which scenario is happening?

1. concatenate all the model regressors onto one column, add the nuisance
regressors and constant terms into one big matrix (X.mat) to estimate the
beta values
2. create a matrix for each run separately and estimate the betas. Save
regression coefficients, compute contrasts and significances of contrasts.
The end (default) result is the average (i guess average of all the
estimated quantities).

>From the help message it looks like it is #2, and if thats the case then
X.mat looks like its a summary. I ask this because I would like to use a X
that looks something like below:
[image: Inline image 1],

which is essentially the scenario in #2, but the output of X.mat looks like
this:

[image: Inline image 2]
(the image hasn't been normalized so that is why there are blank spaces for
3 of the 6 nuisance regressors)

There are slight differences between the two (so it doesn't matter in the
long run) but I just want to know which one is being used. On a quick look
of selxag3-sess, the matlab files look like compiled mex files, so I can't
access them.


Thanks!

[Freesurfer] FS-FAST outputs is X.mat used? {Disarmed}

2017-08-15 Thread Kevin Aquino
Dear all,

I have a question regarding the output from selxavg3-sess. I noticed that
within an analysis there  is a X.mat that looks like a design matrix --
however is this used at any stage of the analysis?  The help message in
selxavg3-sess reads:

"This program will construct the design matrix for each run, fit the GLM,
save regression coefficients, compute contrasts and significances of
contrasts. The runs are combined together so the output is the average
across runs (some would call this a "second-level" analysis)."

so this looks like that x.mat is constructed and used for each run (and not
saved by default). This then looks like X.mat is not used in the analysis
-- it is just there for illustrative purposes? or have I misinterpreted the
help message.


If this is correct (i.e. X.mat in the output is not used) when making
contrasts using mkcontrast-sess, is there a way to parametrically modulate
each run? e.g. to model behavioural changes per run etc.

Hi Doug,

Thanks for that! with regards to your last point

Unfortunately, it does not help much. Much was made of the bug that Eklund,
et al, found in the alphasim program (the AFNI mc simulator), but even
after fixing it, the volume-based analyses still had very high false
positive rates. This is because the problem is that the smoothness in the
data is not Gaussian, so any method that assumes Gaussianity will be
inaccurate.


>From what I read, the MC simulations on the surface uses this Gaussian
assumption. Do you have any ideas (or something in the works) on how to
handle these issues on a single subject level? - since the permutation test
won't be applicable.

Re: [Freesurfer] mri_mcsim for individual subjects and references {Disarmed}

2017-05-15 Thread Kevin Aquino
Actually,

would would be preferable would be running a permutations test something
that you describe in:

http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg49846.html

is there an easy to run mri_glmfit-sim's permutation simulations on a
single subject?
I've run through the FS-FAST pipeline

mkanalysis-sess -fsd bold -surface self rh -fwhm 4.5 -event-related
-paradigm attn.par -nconditions 4 -spmhrf 0 -TR 1.9 -analysis
myanalysis -per-session
-refeventdur 450 -force -nuisreg moco.txt -1 -polyfit 0
mkcontrast-sess -analysis myanalysis -contrast attn -c 1 -a 2 -a 3 -c 4
selxavg3-sess -s SESSION -analysis self_attn_sm_reg.rh -no-preproc -fwhm

But mri_glmfit-sim is expecting the output from mri_glmfit

mri_glmfit-sim --glmdir . --perm 1000 3 pos --log ./selxavg3.log
>> ERROR: cannot find ./mri_glmfit.log

should I just run mri_glmfit with the appropriate flags, or is there a
mri_glmfit-sim version for data that has passed through selxavg3 ?

[Freesurfer] mri_mcsim for individual subjects and references {Disarmed}

2017-05-15 Thread Kevin Aquino
Hi all,

First of all, Freesurfer V6 is working like a dream, my 0.7 mm
segmentations are running really well and in comparisons to hi-resrecon in
5.3 and early beta, I'm having to do fewer manual corrections!


Now for my questions,

1. I'm running mri_mcsim in order to correct for multiple comparisons via
the FS-FAST stream. I'm wondering how many iterations are advised, and how
can one check for convergence in an automatic fashion.

I've run the simulations with 1000 and 10,000 iterations on a 1mm
segmentation with the FWHM simulations at 8mm. (i.e. using mri_mcsim --o .
--base mc-z --save-iter  --surf subject lh/rh --nreps 1 --fwhm 8) and I
can't see many differences between the two when correcting for multiple
comparisons (i.e. using cluster-sess -analysis  myanalysis -thresh 3 -cwp
.05 -s SESSION -sign pos).

2. I'm trying to find some references that detail the simulations and form
the corrections, does anyone have advice which list I can read/start off
with, as well as some key papers that use it (esp on a single subject
level). I really like this approach and It does look to circumvent (I
think...) a lot of the problems of cluster-wise corrections described with
Eklund et al. (Cluster failure paper).

Re: [Freesurfer] Re. display SPM results on inflated surface? {Disarmed}

2017-04-05 Thread Kevin Aquino
Hi Douglas,

I am wondering, where did you find the mini 152 T1 map? :)

Regarding this...
Would it be better to instead run recon-all on a higher-res MNI atlas? and
then run mri_vol2surf for that segmentation?

You can use mri_surf2surf with the -nsmooth flag but just remember to set
the target and source subject as the same subject,

[Freesurfer] Re-running recon-all in V6 {Disarmed}

2016-12-30 Thread Kevin Aquino
Hi all,

When V6 is released I'd want to re-run all my (10) subjects through
recon-all again (they were processed with v6 alpha). I'd like to keep all
my wm edits, mask and control points, is it as easy as just running
recon-all on the same folder again? They are 0.7mm so I'd like to keep all
the corrections.


Cheers!

Re: [Freesurfer] Processing 7T data

2016-10-06 Thread Kevin Aquino
Hi Damien,

I have tested using the HighResRecon vs Freesurfer beta on 0.7 mm^3 data
and have preferred the segmentations on the beta version.

[Freesurfer] Using freesurfer on a partial brain

2016-01-19 Thread Kevin Aquino
Dear Freesurfer list,

I was wondering if anyone here has used freesurfer on anatomical scans
acquired on a partial brain?

I realise that recon-all and many of the tools are suited for a full brain,
but I was wondering if anyone out there has had experience making the tools
work for this scenario? Not necessarily the parcellations and the full
set-up, but other tools such as segmentation, creating a white and pial
surface and topology fixes.

Re: [Freesurfer] high resolution data using recon-all

2015-10-12 Thread Kevin Aquino
Hi Falk,

Just to jump on this as well – does FS 6.0 make HiResRecon redundant?

– I've been using HiResRecon [working like a charm :) ] and wondering if FS
6.0 will cut the need for that workaround.

[Freesurfer] mris_surf2vol

2015-10-02 Thread Kevin Aquino
Hi all,

I am trying to "voxelize" the cortical surfaces generated in freesurfer and
I am a little stuck.

I have been using mris_surf2vol with the --mask option however this
generates a very speckled representation of the cortical surface on the
voxels. What I would prefer would be the level sets of the cortical surface
interpolated onto voxels, even if they are at a different resolution that
could be enough. Is this possible with any of the available commands?

I also went down the route of mris_volmask however, this generates the
cortical ribbon, which is something that I don't need.

For example, in the image attached:
