Reconnection events along neutral lines form the photosphere to higher heights in the atmosphere are believed to be behind the formation of filament channels, the seeds of CMEs. A large number of cancellation events in coordination with SST (Halpha - looking for heating events such as Ellerman bombs) is needed to elucidate the physical processes behind the creation of filament channels.
