通过Python3.5在Windows 10上使用BET时，“在主机上找不到命令‘打赌’”错误

Question

我需要在.nii图像上做大脑提取。我在Windows 10上使用Anaconda，并且有一个基于Python3.5.4的环境。在Nipype上，我从FSL中找到了BET，我遵循了代码：

mybet = fsl.BET()
mybet.inputs.in_file = 'example.nii'
mybet.inputs.out_file = 'example_bet.nii' 
result = mybet.run()

请注意，我希望输出文件example_bet.nii是由fsl.BET创建的，而不是被覆盖的图像。我只能找到基于Unix系统的解决方案，而且似乎需要在基于Unix的操作系统上安装FSL，这在Windows中没有虚拟机是不可能的。嗯，这是我得到的输出：

我需要切换到Linux，还是有办法绕过它？

您只能通过Docker、虚拟机或Linux下的Windows子系统在Windows上使用FSL。天真地运行是不可能的。
