How to Adjust the Sample Rate of the Data in DIAdem

How can I adjust the sample rate of the data in DIAdem to reduce the number of data points, or generate intermediate points in my data channel?

  1. Create a new time channel with desired sampling rate using the Generate Numeric Channel function located in ANALYSIS >> Channel Function palette.  
    Note: If you already have a channel loaded in DIAdem with the desired sample rate, this step can be skipped.
  2. Use the Linear Mapping function located in ANALYSIS >> Channel Function palette to resample the data according to the desired new time channel. 
  3. Select the Mapping Mode function to generate intermediate points with interpolation, or just delete extra samples that you don't need.

    As a result, DIAdem will generate a new channel with the resampled values.
