Hi,
I'm afraid that FSL has never supported RGB and is unlikely to - sorry.
As this type stores three 8-bit values per voxel, that will also make it
very
difficult to convert to another type. The easiest way is probably to write
a header where the 4th dimension is 3 (or 3 * number of time points) and
the datatype is 8-bit (datatype 2). This would then allow it to be read
in, but
would require reshaping to get into another form if that's what you want,
which could be done using matlab.
Hope this helps in some way.
All the best,
Mark
