Thank you very much for the very helpful reply!
This is what I mean with averaging. I am recording a signal reflecting spiking behavior. I need high sampling rates to make sure I capture the spikes, for e.g. 1kHz.
Because this implies very large files over long recording periods, I would be interested in two options:
1) An automated manner of saving files of a fixed size throughout my acquisition. So: record at 1kHz for 10 hours, but save consecutive files every some Megabytes.
2) As a compromise, it could be OK to log at 1Hz (capture the interesting peaks) and then, instead of saving at 1kHz, save only the average of every 100 samples (which corresponds to compressed files)
Is there a way to try these two options on the Waveforms software?
with best regards, Eleni
