Hi,

This all looks fine, and there is no problem with the data type.
What can be a problem sometimes (though I can't tell if it is in this case or not) is the presence of NaN values in the image.  FSL is not happy with these values, though they can be easily removed.  Just run:

fslmaths Pid_FUNC -nan Pid_FUNC_nonan

and then try again with the new file (Pid_FUNC_nonan).

Hopefully that will fix the problem.
If not please email back but provide more details about exactly what you have run and more information from the error (e.g., the log file).

All the best,
        Mark
