ERROR : Base home directory does not exist within the container: /brain#
用沙盒模式创建镜像，然后以交互方式进入镜像后创建/brain目录。之后将沙盒格式的镜像打包为.img文件即可。
# 创建沙盒镜像
singularity build --sandbox centos7 docker://centos:7
# 以交互方式打开镜像
singularity shell --writable centos7/
Singularity: Invoking an interactive shell within container...
# 镜像内创建缺失目录
Singularity centos7:~/envs> mkdir /brain
Singularity centos7:~/envs> exit
# 重新打包镜像
singularity build centos7.img centos7/ERROR : Home directory is not owned by calling user: /usr/local/singularity-2.5.2#
报错命令：singularity shell smriprep.simg
解决方法：添加–home xxx参数，这里必须是绝对路径。例如：singularity shell –home /babri/sangf/Desktop/test/ smriprep.simg
