I have thought about ways of doing this in BioEra. One idea would be to have several edf filereaders. When the forst reaches end of file the second could start and send out its data. continue that loop until last file is read Another might be to find a way to load multiple files from a list of sort and have them process through. Any suggestions or comments Thanks George

And it generates edf/out.edf file which should be the concatenation of all those edf files (after you stop the design).
