[BUG] fivettgen_hsvs_.py

[arkiev]

Description

When 5TTgen hsvs is executed, the task runs to completion. However, after the task finishes, the following error occurs.

How to reproduce

Here's the code for the task:

    wf.add(
            FivettGen_Hsvs(
                in_file=wf.FastSurfer_task.lzout.subjects_dir_output, 
                out_file="5TT_hsvs.mif",
                name="fTTgen_task",
                nocrop=True,
                sgm_amyg_hipp=True,
                nocleanup=True,
                white_stem=True
            )
        )

Note that the default fivettgen_hsvs_.py file was used here, with the exception being:

output_fields = [
    ("out_file", ImageOut, {"help_string": "The output 5TT image"}),
    (
        "scratch",
        Directory,
        {
            **"mandatory": False,**
            "help_string": "manually specify the path in which to generate the scratch directory."
        },
    ),
]

Screenshots
