Hi Hannah,

If the option to keep the data in double precision (menu File > Memory option) is unchecked then the data will be in double precision. If this is not the case, then I do not know. Maybe submit a bug report so we can investigate further.
Best wishes,

>> Arno, if you advocate keeping the data in single precision you may want to note that the pop_loadset function converts the data to double if two files do exist (fdt/set). This still seems inconsistent to me, I apologize in advance if I am wrong.
