    hi all professiond;)

    some times i think about the output format of SeaKeeper software.
    thats format are text and used of them was a little difficult( only a little:D )

    ok, so i try to fine some VBA code on Excell to change this format to a abular and sorted data for draw some usful graph.

    any body....?:!:

    I try to write a VBA macro for show the acceleration data from seakeeper data file:

    data file:

    but i hav'nt the MSI data to compose the MSI curve on the Accel. Graph.
    any body can help me????:( :?: :?:

    The MSI tab in the results window can be saved as text or copied and pasted into Excel. That should let you do it.
