1) I suppose it wouldn't be hard to read doubles, as long as you don't mind them being converted to floats internally - AFNI isn't much setup to deal with double-valued datasets.

2) Reading FIASCO formatted datasets is on my to-do list. I'm even thinking of doing it - or rather, delegating it to someone. But I don't know when that will be accomplished.
