TIFF library warning problem while reading the image data and meta data of a .tiff file?

I was trying to have a look at the Image data and Meta data from my TIFF files. I followed the steps mentioned in the Mathworks help section of Importing Images Documentation http://de.mathworks.com/help/matlab/import_export/importing-images.html#br_c8to-1.

The following is the result when i tried to create a Tiff object for a single .tiff file:

>> Im_tiff = Tiff(filename, 'r')

Warning: TIFF library warning - 'TIFFReadDirectory: Unknown field with tag 37000 (0x9088) encountered.'

Warning: TIFF library warning - 'TIFFReadDirectory: Unknown field with tag 37005 (0x908d) encountered.'

Warning: TIFF library warning - 'TIFFReadDirectory: Unknown field with tag 37006 (0x908e) encountered.'

Warning: TIFF library warning - 'TIFFReadDirectory: Unknown field with tag 37010 (0x9092) encountered.'

Im_tiff =

                  TIFF File: 'C:\PROJEKTE\FFG_USEML\Zeilenkamera\2013_11\00_Dirty Small\unknown\20131113_025243_00040.tiff'
                       Mode: 'r'
    Current Image Directory: 1
           Number Of Strips: 1
                SubFileType: Tiff.SubFileType.Default
                Photometric: Tiff.Photometric.MinIsBlack
                ImageLength: 93
                 ImageWidth: 184
               RowsPerStrip: 4294967295
              BitsPerSample: 8
                Compression: Tiff.Compression.LZW
               SampleFormat: Tiff.SampleFormat.UInt
            SamplesPerPixel: 1
        PlanarConfiguration: Tiff.PlanarConfiguration.Chunky
                Orientation: Tiff.Orientation.TopLeft

The objective for me is to access the data which is included in the tagID 37006 (0x908e). Therefore, I was trying to figure out the reason behind the occurrence of such warnings in the first place. Currently, i don't have an idea where to start.

If anyone has encountered the above mentioned problem before, please give me your suggestions.
