What do the values of datatype in fslhd and fslcreatehd mean?

The datatype values refer to codes used in the Analyze format to specify the type of data stored in the image. The valid values supported by FSL are:

• 2 = unsigned char [8 bit]
• 4 = short int [16 bit]
• 8 = int [32 bit]
• 16 = float [32 bit]
• 64 = double [64 bit]

Also, there is limited support (mainly in prelude, fugue and fslcomplex) for:

• 32 = complex [64 bit as 2 by 32 bit floats]
