Hi Janine, I drove the question you sent to the ldm-users email list into our inquiry tracking system since I didn't see anyone chime in with comments... re: > I have been saving ACARS data off the LDM and just recently realized > that I left off the -overwrite. So, this resulted in multiple times being written into a single output file, or did it result in multiple copies of the same reports being written? What was your LDM pattern-action file action that FILEd the messages? re: > Is there a way to read these files and extract the good data from the end? Yes, if you have a program that understands the structure of the products that were written into the file. re: > Or is my only option to repopulate my archive from the MADIS archive? I don't think that this should be needed. Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
