changing interval MATLAB file

[FTI_Monkey]

Hi,

Apologies if this is an obvious question but I'm fairly new to Diadem and still learning!

I'm importing a MATLAB file, which is a accelerometer signal of a sine wave. The data is recorded at 8000Hz, so when it imports 1 second is equal to 8000 data points. I belive need to change the interval to 1/8000 to convert the X data to seconds, but I'm not sure on how to do this? Can someone point me in the right direction?

Thanks

Hi FTI,

It's hard to know for sure without seeing you data file, but it sounds like you would be best served to convert all your loaded data channels into waveform channels.  Here's a VBScript that does that for the particular cas of an 8000Hz sampling rate.

FOR Each Group In Data.Root.ChannelGroups
  FOR Each Channel In Group.Channels
    Call ChnWfPropSet(Channel, "Time", "s", 0, 1/8000)
  NEXT ' Channel
NEXT ' Group
