  ImageSeries:
    name: ImageSeries
    description: General image data that is common between acquisition and stimulus
      time series. Sometimes the image data is stored in the file in a raw format
      while other times it will be stored as a series of external image files in the
      host file system. The data field will either be binary data, if the data is
      stored in the NWB file, or empty, if the data is stored in an external image
      stack. [frame][x][y] or [frame][x][y][z].
    is_a: TimeSeries

        required: false
      external_file:
        name: external_file
        description: Paths to one or more external file(s). The field is only present
          if format='external'. This is only relevant if the image series is stored
          in the file system as one or more image file(s). This field should NOT be
          used if the image is stored in another NWB file and that file is linked
          to this file.
        multivalued: true
        range: text
        required: false
      format:
        name: format
        description: Format of image. If this is 'external', then the attribute 'external_file'
          contains the path information to the image files. If this is 'raw', then
          the raw (single-channel) binary data is stored in the 'data' dataset. If
          this attribute is not present, then the default format='raw' case is assumed.

  ImageMaskSeries:
    name: ImageMaskSeries
    description: An alpha mask that is applied to a presented visual stimulus. The
      'data' array contains an array of mask values that are applied to the displayed
      image. Mask values are stored as RGBA. Mask can vary with time. The timestamps
      array indicates the starting time of a mask, and that mask pattern continues
      until it's explicitly changed.

  OpticalSeries:
    name: OpticalSeries
    description: Image data that is presented or recorded. A stimulus template movie
      will be stored only as an image. When the image is presented as stimulus, additional
      data is required, such as field of view (e.g., how much of the visual field
      the image covers, or how what is the area of the target being imaged). If the
      OpticalSeries represents acquired imaging data, orientation is also important.

      orientation:
        name: orientation
        description: Description of image relative to some reference frame (e.g.,
          which way is up). Must also specify frame of reference.

  IndexSeries:
    name: IndexSeries
    description: Stores indices to image frames stored in an ImageSeries. The purpose
      of the IndexSeries is to allow a static image stack to be stored in an Images
      object, and the images in the stack to be referenced out-of-order. This can
      be for the display of individual images, or of movie segments (as a movie is
      simply a series of images). The data field stores the index of the frame in
      the referenced Images object, and the timestamps array indicates when that image
      was displayed.
