Linux Freesurfer脑数据分割

1. 安装见官网

https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall

注意每次使用之前都要设置环境变量

## bash
$> export FREESURFER_HOME=/usr/local/freesurfer
$> source $FREESURFER_HOME/SetUpFreeSurfer.sh

一劳永逸在/bashrc中设置也可以，我选择每次都设置，没有原因

2. 测试例程

$ cp $FREESURFER_HOME/subjects/sample-001.mgz .
$> mri_convert sample-001.mgz sample-001.nii.gz
