Reading Dasylab files at different time stamps simultaneously

[sam_Samuelson]

I have 4 pressure readings I would like to "sync up" by using the "read extract" options in the read data module. Is there a way to do this? i.e. waveform 1 capture 5-20s, waveform 2 capture 30-45s, etc...

The Read Extracts option looks at the time stamp to determine when to read the file. If all four files were acquired with identical sample rates, it should work as described in the Help. However, if the sample rates differed, it would extract more data. DASYLab is fussy about the data; for instance, the File Write wants its inputs to have the same amount of data. One way around this is to use the Signal Adaptation module. It will sync its inputs (1 - n) to the first input. I recommend the linear interpolation setting.
