Flexcom supports two different schemes for laying out the data in the RAO file (assuming you are not importing RAO data directly from a third party software such as WAMIT®), namely the MCS layout and the Line layout. This former is the standard layout traditionally used by Flexcom. The Line layout is a more recent addition to the software, and it represents a more general layout that, for example, simplifies copying and pasting RAO data from spreadsheet programs.
