关于我尝试读取 .FIT 文件时的异常

我有一个包含 .FIT 文件的文件夹，我有这个代码来读取它们：

private static void readFitFile() {

    try {
        List<File> filesdebuglder = Files.walk(Paths.get(LOCAL_EXPANDED_DATA_PATH))
                                         .filter(Files::isRegularFile)
                                         .map(Path::toFile)
                                         .collect(Collectors.toList());
        System.out.println("There are " + filesdebuglder.size() + " .FIT files in folder " + LOCAL_EXPANDED_DATA_PATH);

        for (File afile : filesdebuglder) {
            System.out.println("Doing something cool with file " + afile.getName() + " ...");
            Fits fitsFile = new Fits(afile);
            ImageHDU imageHDU = (ImageHDU) fitsFile.readHDU();
            StandardImageTiler tiler = imageHDU.getTiler();
            // The exception happens with getCompleteImage() method
            float[][][][] tmp = (float[][][][]) tiler.getCompleteImage();
            System.out.println("tmp is " + tmp);
            float[][] imgData = tmp[0][0];
            System.out.println("imgData is " + imgData );


        }

    } catch (FitsException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch(ClassCastException e) {
        e.printStackTrace();
    }

}

我得到这个输出：

There are 409 .FIT files in folder resources/wetransfer-39ab61
Doing something cool with file RN20130622_1x1_SIN FILTRO_000102206.REDUCED.FIT ...

我正在使用最新的库依赖项，并且可以使用 GIMP 打开 FIT 文件。

    <dependency>
        <groupId>gov.nasa.gsfc.heasarc</groupId>
        <artifactId>nom-tam-fits</artifactId>
        <version>${nom-tam-fits.version}</version>
    </dependency>

<properties>
    <nom-tam-fits.version>1.15.2</nom-tam-fits.version>
</properties>

我正在尝试读取带有 .FIT 文件的文件夹并训练使用 deeplearning4j 来训练模型来识别这些文件的内容，但由于异常，我无法读取任何文件。我做错了什么？

编辑。这是正确的代码：

private static void readFitFile() {

    try {
        List<File> filesdebuglder = Files.walk(Paths.get(LOCAL_EXPANDED_DATA_PATH))
                                         .filter(Files::isRegularFile)
                                         // .filter(line -> line.getName(0).toString().contains(".FIT"))
                                         .map(Path::toFile)
                                         .collect(Collectors.toList());
        System.out.println("There are " + filesdebuglder.size() + " .FIT files in folder " + LOCAL_EXPANDED_DATA_PATH);
        int count = 1;
        for (File afile : filesdebuglder) {
            System.out.println("Doing something cool with file " + afile.getName() + " ...");
            Fits fitsFile = new Fits(afile);
            ImageHDU imageHDU = (ImageHDU) fitsFile.readHDU();
            StandardImageTiler tiler = imageHDU.getTiler();
            short[][] tmp = (short[][] ) tiler.getCompleteImage();
            System.out.println("tmp is " + tmp);
            short imgData = tmp[0][0];
            System.out.println("imgData is " + imgData );

            count ++;
            System.out.println("Done with the file " + afile.getName() + " ... " + count);
            fitsFile.close();

        }

    } catch (FitsException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch(ClassCastException e) {
        e.printStackTrace();
    }

}
