   * ``experiment`` - e.g. number and type of acquisitions
   * ``metadata`` - e.g. channel information including name
 
+This data is imported into the ND2reader object when a file is opened. However, to inspect the data yourself, you can use the method ``readMetadata``:
 
+``` matlab
+attrib = readMetadata(obj, 'attributes');  %Returns metadata in a JSON string
+attrib = jsondecode(attrib);  %Convert JSON to struct
+```
+
+## File attributes
+
+The file attributes contain information necessary to initialize pointers to the picture. The attributes contains the following fields:
 
+* ```bitsPerComponentInMemory`` - Number of bits to hold each component (channel)
+* ```bitsPerComponentInMemory`` - Number of bits to hold each component (channel)
