How to adjust Time zero

[Giova]

Hello,

I've a data file with a time history from -1 sec. to 4 sec.

Is it possible to modify the time zero in such a way to have the T=0 at the beginning of a certain event?

Thanks

Hi Giova,

Sure.  First you need to find the row/time that the event occurs, then you need to subtract that time value from all the values in the time channel. You can use the ChnFind() function to find the row, then the ChD() command to find the time value for that row, then the ChnLinScale() function to subtract that time value to zero the time access at that point.
