FSL
安装
FSL目前只支持PYTHON 2.X .
安装说明:https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FslInstallation/Linux
完整版下载地址:http://neuro.debian.net/install_pkg.html?p=fsl-complete
在linux下的安装非常简单, 只需要打开终端, 输入 sudo python2 fslinstaller.py 即可完成安装.安装后需要重新登录当前用户,或者重启一下系统, 更新系统环境变量.
检查是否安装成功, 就需要在终端输入
echo $FSLDIR
flirt -version
echo $FSLDIR 检查安装路径; flirt -version检查FSL版本.
功能
FSL可以对各种核磁数据进行处理. 核磁数据类型和FSL命令的关系如下:
- 功能核磁共振: FEAT, MELODIC, FABBER, BASIL, VERBENA
- 结构核磁共振: BET, FAST, FIRST, FLIRT & FNIRT, FSLVBM, SIENA & SIENAX, MIST, BIANCA, MSM, fsl_anat
- 弥散核磁共振: FDT, TBSS, eddy, topup
- GLM / 统计: GLM general advice, Randomise, Cluster, FDR, Dual Regression, Mm, FLOBS
- 通用 : FSLeyes, FSLView, Fslutils, Atlases, Atlasquery, SUSAN, FUGUE, MCFLIRT, Miscvis, POSSUM, BayCEST
