Did you know . . . The OmniPlex Records Various Types of Data Simultaneously?

The interactive data acquisition software for the OmniPlex Neural Data Acquisition Systems, known as PlexControl, offers users a convenient interface capable of quickly and conveniently selecting from a variety of different data types available for recording. For example, a researcher is able to record such diverse sources as “Continuous Wideband,” “Continuous Spike,” “Field Potential,” and “Spike.”For the sake of simplicity, a source can be defined as the channels of data produced by a hardware or software device. In order for a specific source to be captured into a .PLX or .PL2 file, it first must be enabled in the PlexControl interface. It is useful to note that more than one source may be selected for the same channel at the same time.
To do so, open the “Properties Spreadsheet” tab in PlexControl. Ensure that the boxes under the desired “Rec” (Recording) sources are checked. Then, to ensure that a specific channel within a source is recorded, the “Enabled” checkbox must be checked as well. It is imperative that the box is checked for every channel of every source of data that is expected in the recorded file. It can be frustrating for a researcher to record a significant amount of data, only to learn that he or she has recorded data from unintended sources, or that the desired data never even showed up in the recording only because the configuration was not selected properly pre-recording.
Another friendly suggestion would be to record a very short sample file for verification. This can go a long way to ensuring that a long recording will contain all the desired data. We encourage researchers to be vigilant of this process before recording.
As always, if you have any questions or would like to discuss anything further, please feel free to email support@plexon.com and somebody from the team will be glad to get back to you.
