const neuro_recv::dish_state CsvReceiver::parse	(	const std::string &	s,
		bool	record_time
	)		`[private]`

Parses a single line in a CSV file and returns a new dish state.

The input string must be 61 comma-separated values. The first value is an index and is ignored. The remaining 60 values are voltages for each channel in the MEA.

Parameters:
