Re: [Freesurfer] Intermediate stages of cortical inflation

yes, it's pretty much the same algorithm, and no you cannot preserve 
surface area as we are essentially mapping to the unit sphere (actually 
it's a sphere with r=100mm I think, but there is really no difference)

also enforce the surface area? Thanks.

 if it's just for visualization you ca use -i, but in general we just
 project and unfold on the sphere (and don't use -i which inflates and
 drives the surface to the sphere)

Re: [Freesurfer] Intermediate stages of cortical inflation

2014-04-10 Thread Xuelong Zhao
Thanks for pointing this binary out- I didn't realize the user could access it 
outside of recon-all.
I've
 had a look at the fswiki for mris_sphere and it doesn't seem to be 
complete. I used it in the following format but not sure if this is 
correct:

mris_sphere -n 160 -w 20 -scale 1 lh.orig lh.sphere_test

I
 want to check that the above command converts lh.org to a sphere in 160
 iterations, writes out every 20th iteration and ensures the area is 
preserved? 

Also, on the fswiki site:

mris_sphere [options] surface file patch file name output patch 
I'm
 not certain if output patch is synonymous with output surface? 
Also, what is the purpose of a patch file name? Thanks.

 yes, many of our binaries take the -w n flag to write out a snapshot of 
 the minimization every nth step, including mris_sphere

   you can use -w 1 to write out every step in the inflation process and
   choose what you want. If you want it to preserve surface area during
   inflation (as opposed to just at the end), also include -scale 1

[Freesurfer] Intermediate stages of cortical inflation

2014-04-08 Thread Xuelong Zhao
Hi, 

I would like to ask whether it is possible to display different levels of 
cortical inflation?

I have been using the command: mris_inflate 

but the -dist and -n flags do not seem to make that much difference. Also, if I 
use fsaverage lh.orig as the input file and using the default options for 
mris_Inflate I don't seem to be able to recover the lh.inflated surface. 

Are there any alternative commands to control the level of inflation? Thanks.
