I tried using the file generated by the code above in'vibriton data'. After clicking sevral buttons I reached a screen that says the data file should have two columns: time and acceleration. And after experimenting, I found that it 'vibraitondata' looks for an array in memory, rather than a file on disk. Therefore I am changing the last line of hte code I posted above, from
Then I make selections in 'vibrationdata': Under "Signal Analysis Functions", I select "Time History" and "Acceleration" and "ISO Generic VC, 2631, 10816'. Then I click the button "Begin Signal Analysis". A new window pops up. In that window, I select "ISO 2631 Human Vibration". Then I click "Analyze". A new window pops up. In that window, I enter Input Array Name=data1 (because I have alrady created that array with my script), Unit=G, Mean Removal=Yes, start time=0 sec, end time=60 sec, Weight='Wk, Z-axis, seat', Segment Duration=10 sec, Percent Overlap=50. Then I click the button "Calculate". Three figures pop up see below, and a window pops up that says "Results written to command window.". I click the "OK" button in that window and it disappears.
I had the same result as you ("Warning: nnn>500000") when I left start time, end time, and duation fields blank, and then I clicked "Calculate".
