Issue running nipype.interfaces.spm

[nmossazg12]

Hi, I am experiencing issues running nipype.interfaces.spm in my windows machine. I get "This docstring was not generated by Nipype! " error message when I run the following command. Any assistance to resolve this issue would be appreciated. Thank you!

Actual behavior

>>import nipype.interfaces.spm as spm^M
>>est = spm.EstimateContrast()

'stty' is not recognized as an internal or external command,
operable program or batch file.

The above exception was the direct cause of the following exception:

Execution environment

python version 3.9.16
nipype version 1.8.4

Nipype is not supported on Windows. You may be able to use the Windows Subsystem for Linux to get it working, however. I don't know, though.
