Thanks for the NDF files. I open M1685495718 in the Neuroplayer, check the Verbose button, and step through the first second. This second contains eight errors.The clock is jumping:
Clock Error: index=59 current=78 previous=51
Clock Error: index=102 current=105 previous=78
Clock Error: index=223 current=133 previous=106
Clock Error: index=440 current=162 previous=135
I check "Sequential" and then press "Reload" to calculate the length of the file by counting the number clock messages. There should be 128 clock messages per second. By this measurement, the file is exactly 3600.0 s long. The same is true for the other four files. And yet each file took roughly two hours to record.
Diagnosis: There are two processes downloading data from the same data receiver. Your Neurorecorder is getting only half the data, so it's taking two hours to get one hour's worth of clock messages.
Suggestion: Check to see if you have two independent processes reading from your data receiver. You may have two Neurorecorders running, or you may have a Receiver Instrument running as well as your Neurorecorder Tool.
Explanation: The Neurorecorder runs as a separate process, using its own Receiver Instrument to download data from your Octal Data Receiver. If you open a Receiver Instrument using the Instrument Menu in your original LWDAQ program, this second Receiver Instrument will be entirely independent of your Neurorecorder. If you use this second Receiver Instrument to view live data from your Octal Data Receiver, you will have two processes downloading data, and each process gets only half.
So, I think that's what's happening. Apologies for confusion caused by the upgrade to LWDAQ 10.5.5.
