DataView can read CED files in the native Spike 2 (smr) and Signal (cfs) format.

For Signal files the data have to be recorded with a single sample rate. If the files contain multi-sweep data, the sweeps are concatenated one after another, and the start of each sweep is indicated by an event. The experimental elapsed-time is available through the event parameters.

For Spike 2 files, different data channels can be recorded with different timebase settings, and there can be gaps in the record. Both waveform and event-only files can be displayed (the latter with a dummy data trace).
