What incorrect in the version 2 of MapM file is which fiber has which object in it. It would be good if plate-mapper only keeps committed files. Uncommitted MapM files should not used, so they are better not been copied to host2. I think the data are probably good too. But need to use version 1 MapM files to figure out which fiber has which target's spectrum. -kaike On Oct 27, 2008, at 9:36 AM, Stephen Kent wrote: > Kaike, > > I don't think there is a problem with the database.
