nq2ring is a MiniSEED data file feeding program for Earthworm. The utility was written for the No Cal Seis Net NetQuakes project by Jim Luetgert.
nq2ring is designed as a multi-threaded program. The main thread loops polling the input directory, for new MiniSEED data files arriving from the NetQuakes server. Once data arrives, the data is converted into an earthworm trace buffer and shipped off to the earthworm transport ring.
