[Freesurfer] How to threshold an input mutli-volume?

2009-07-07 Thread 李猛
Hi, all.
Can mri_threshold  threshold an input mutli-volume file? With a seven
volumes NIFTI file, all voxels other than in the first volume are set to
zero. In addition, the help for mri_threshold options is very limited. There
is nothing about the options.

Usage: mri_threshold [options] in vol thresh out_vol
This program will threshold an input volume

Where do I get more detailed  description?
Best Regards.

I guess it would be pretty easy to fix to work on multi-frame images. 
What hardware/software platform are you using?

Thank you in advance for your help.
We installed the freesurfer on a ubuntu 8.04 i686 machine.
