different results for the same configuration after initialization #536

Open neurochen opened 1 year ago

A bug for the GUI was observed on Windows 10. When adding the acquisition board plugin into the data flow for the first time, it shows the correct voltages. But when we load the same configuration next time, it often resulted in a visualization of the filtered high-frequency band responses even though the filter is set for low-frequency LFP components. Could you please take a look at it? Thanks.

Please see below for the configuration file. filter_bug.log

Was there any change to the acquisition board after the GUI was closed (e.g. headstages added or taken away)? It's possible that this caused the Bandpass Filter to classify this as a new data stream and re-initialize with the default settings.

If the acquisition board was in the same state, it would be helpful to know how reproducible this is. Does it happen every time you re-load this signal chain, or only sometimes?
