that's correct the re-created time history is not unique. There are tools out there that can be used to reconstruct a time history using wavelets (see ref. NASA/TM 2008-215253). I am using one of them. I am simply looking for the possibility of a mcad sheet to do it rather than relying on a 1/3 party tool (it simply means that I can "control" the tool)
