[Freesurfer] Fwd: freeview error

2013-12-30 Thread rujing cha

Hi Bruce and others,
Thanks Bruce. I had installed the centos6.5 x86_64 in my computer, and
setup the freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0.tar.gz,
and I setup the nvidia drivers completely. Then I tried to run this
command:
freeview -f
$SUBJECTS_DIR/fsaverage/surf/lh.inflated:overlay=lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/mc-z.negative.sig.cluster.mgh:overlay_threshold=2,5:annot=lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/mc-z.negative.sig.ocn.annot
. It did present the underlay(lh.inflated),overlay and annot, but it
suspended when I click the button "configure overlay". Then freeview
were suspended. The CPU ran "100%",and memory ran "23%". There was
nothing to do but terminated it manually in the command console by
"ctrl + c".
I want to know why I cannot configure overlay. Is it a poor graphic
card or CPU or memory? My graphic card is "NVIDIA GeForce 8600 GT",
and CPU is "Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz 2.40GHz", and
RAM is 2.00G.
Thanks Bruce and others.
All the best.

Re: [Freesurfer] mri_mask output problem

2013-12-30 Thread Caspar M. Schwiedrzik

Hi Doug,
thanks for your input. I turns out that there is some problem when
converting minc to NIFTI with float. I got a hold of the original minc file
and converted it to NIFTI with minc2nii using integer, and now the values
are in a reasonable range and the skull stripping works.
Thanks!
Caspar

Re: [Freesurfer] mri_mask output problem

2013-12-30 Thread Douglas Greve



That should not be a problem. Certainly it should not cause everything 
to go to 1s and 0s. What version of FS are you using? And you say the 
same thing happens with FSL? Try using mri_convert to convert the 
nonbinary image to another nifti file and see if you get 1s and 0s. If 
not, then try that file as input. You can also try fscalc, something like


fscalc input.nii mul mask.nii -o output.nii

should accomplish the same thing
