window环境下关于fMRI的nii文件的预处理的批量代码

配套fMRI预处理使用。之前预处理忘记删前十秒的文件（为什么要删掉？因为前十秒的文件不稳定），于是59个文件夹不仅要保留删除前十秒还没预处理的文件，还要在每个文件夹里删掉大概一共700个左右的各个预处理步骤遗留下的文件。后面问了chatGPT，写了window脚本挺好用的，省了不少事，这里记录一下，分享一下。

 文件地址：https://github.com/zhoushusheng/fMRI_preprocessing

操作步骤：

1. 将脚本复制到记事本中，并保存为 .bat 文件（如 delete_first_ten_files_by_pattern.bat）。
2. 双击 .bat 文件运行，脚本将将执行相应的功能。

delete_non_fMRI_nii.bat

@echo off
setlocal enabledelayedexpansion

for /l %%i in (1,1,35) do (
    if %%i lss 10 (
        set "folder=sbj0%%i"
    ) else (
        set "folder=sbj%%i"
    )

    set "target_dir=B:\fMRI\preprocessing_exclude_10s\CN\!folder!\fMRI"
    
    if exist "!target_dir!" (
        cd /d "!target_dir!"
        
        if exist *.nii (
            echo Processing folder: !target_dir!
            for %%f in (*.nii) do (
                set "filename=%%~nf"
                echo Checking file: %%f

                REM Check if filename starts with "s" followed by exactly 3 digits and an underscore
                if "!filename:~0,1!"=="s" (
                    set "next_three=!filename:~1,3!"
                    set "underscore=!filename:~4,1!"

                    if "!underscore!"=="_" (
                        echo Keeping file: %%f
                    ) else (
                        echo Deleting file: %%f
                        del "%%f"
                    )
                ) else (
                    echo Deleting file: %%f
                    del "%%f"
                )
            )
        ) else (
            echo No .nii files found in !target_dir!
        )
    ) else (
        echo Directory "!target_dir!" does not exist!
    )
)

endlocal

delete_non_MRI_nii.bat 除了fMRI的，MRI里的也要，要不然fMRI预处理读取结构体的时候会报错，因为之前coregister的时候生成了多个..nii在MRI里头。

@echo off
setlocal enabledelayedexpansion

for /l %%i in (1,1,35) do (
    if %%i lss 10 (
        set "folder=sbj0%%i"
    ) else (
        set "folder=sbj%%i"
    )

    set "target_dir=B:\fMRI\preprocessing_exclude_10s\CN\\!folder!\MRI"
    
    if exist "!target_dir!" (
        cd /d "!target_dir!"
        
        if exist *.nii (
            echo Deleting files in !target_dir!
            for %%f in (*.nii *.mat) do (
                set "filename=%%~nf"
                if /i "!filename:~0,1!" neq "s" (
                    echo Deleting file: %%f
                    del "%%f"
                )
            )
        ) else (
            echo No .nii files found in !target_dir!
        )
    ) else (
        echo Directory "!target_dir!" does not exist!
    )
)

endlocal
