Re: [Freesurfer] Very different results between 5.1.0 and 5.2.0

Looking at the image posted previously.

https://yalesurvey.qualtrics.com/SE/?SID=SV_ddwW7I9yMQuCtPn

I think it is pretty clear the 5.1 picture has better gray/white contrast.
It is a very subtle difference, but you can see it if you look at some
pieces of
wm that were missed by 5.2 in this image.

The 5.2 image has been smoothed, by a small degree, relative to 5.1.
Either prior to FS processing or by FS, it would seem.

Daniel,

Unfortunately, since I run all the individuals again with FreeSurfer 5.2, I
just saved from the 5.1 the info I was using for comparison between version
- the aseg stats.

I don't have cortical thickness information for 5.1 unless we run all the
cases again in 5.1

 rh_bankssts_thickness as an example of rh.aparc.thickness.

  While the correlation between the two versions of right-amygdala is r =

  Presumably I believe the correlation should be  .90 for a strong

Dear FreeSurfer Experts,

I ran FreeSurfer 5.1.0 and FreeSurfer 5.2.0 on identical set of 161
subjects, and I'm interested in rh_superior_temporal_sulcus_thickness in
particular.

Previously, the mean thickness is 2.24 mm in 5.1.0; now it is 3.28 mm in
5.2.0. They are significantly different, t(160) = 56.71.

The correlation between the two versions is r = .33

Is this something possible?? I can't see what went wrong in my
procedures.

Thanks!

 Subject: [Freesurfer] Very different results between 5.1.0 and 5.2.0
 
 Dear FreeSurfer Experts,
 
 I ran FreeSurfer 5.1.0 and FreeSurfer 5.2.0 on identical set of 161
 subjects, and I'm interested in rh_superior_temporal_sulcus_thickness in
 particular.
 
 Previously, the mean thickness is 2.24 mm in 5.1.0; now it is 3.28 mm in
 5.2.0. They are significantly different, t(160) = 56.71.
 
 The correlation between the two versions is r = .33
 
 Is this something possible?? I can't see what went wrong in my
 procedures.
 
 Thanks!
 Daniel

Re: [Freesurfer] Very different results between 5.1.0 and 5.2.0

2013-04-10 Thread Pedro Paulo de Magalhães Oliveira Junior
I have processed more that 600 brains with both versions in the last weeks
and the only difference I'm seeing between version 5.2.0 and 5.1, besides
the obvious new features, is processing time.

Version 5.2 is 10% faster than 5.1 in an Amazon EC2 instance.

Besides that there's no visible difference in terms of cortical thickness,
volumes, etc.

If you have access to computer resources to spare you can run recon-all of
both versions in some well known database of images and do a more formal
test.

 Dear FreeSurfer Experts and Users,

 Did anyone find similar things using FS 5.2 (please see my previous post

 I'm not interested in nitpicking but I feel this is a rather serious

 At the meantime I keep receiving Emails from people asking me this issue.

Hi PPJ,

Thanks! It looks interesting. I also found FS 5.2 is faster. Is there any 
chance you could also provide the cortical thickness of the 2009 atlas (e.g.,

I will take a look into the aseg.volume in my data too.

We're repeating our paired-analysis of thickness measures between 5.1

brain.finalsurfs.mgz file with the surfaces overlayed, and check the
intensity value of the voxels which appear to be non-cortical 'black
spaces', relative to neighboring gm voxels.  ignore the aseg.mgz gm
voxels, as those are not accurate (ie, dont load aseg.mgz when
inspecting surfaces, or at least turn if off when inspecting gm
regionsits still handy to see where hippocampus sits).

 Dear FreeSurfer Experts and Users,
 
 Did anyone find similar things using FS 5.2 (please see my previous post
 below)? That is, FS 5.2 is including more non-cortical black spaces
 within pial surfaces, compared to FS 5.1?
 
 I'm not interested in nitpicking but I feel this is a rather serious
 issue, so I would like to raise it again before it's completely forgotten.
 
 At the meantime I keep receiving Emails from people asking me this issue.
 
 Thanks!
 Daniel

Re: [Freesurfer] Very different results between 5.1.0 and 5.2.0

2013-03-19 Thread Yang, Daniel

Posting one of the brains.

https://yalesurvey.qualtrics.com/SE/?SID=SV_ddwW7I9yMQuCtPn


It seems to me that neither version is perfect; however, 5.2.0 is
capturing more black spaces in the region I'm looking at.

It's in the right hemisphere, TAL coordinate about ~ (44, -46, 20).

Given that the correlation between 5.1.0 and 5.2.0 is r = .33 in the
region I examined with my samples, it's not a systematic predictable
bias.

Any solution?

more correct, 5.1 or 5.2.

Subject: [Freesurfer] Very different results between 5.1.0 and 5.2.0

Dear FreeSurfer Experts,

I ran FreeSurfer 5.1.0 and FreeSurfer 5.2.0 on identical set of 161
subjects, and I'm interested in rh_superior_temporal_sulcus_thickness in
particular.

Previously, the mean thickness is 2.24 mm in 5.1.0; now it is 3.28 mm in
5.2.0. They are significantly different, t(160) = 56.71.

The correlation between the two versions is r = .33

Is this something possible?? I can't see what went wrong in my
procedures.

Thanks!
Daniel
