Hi Devon, I looked into this some more, and there's not much I can do to change rtrace without breaking other tools, unfortunately.
I just tweaked dctimestep so that it doesn't insert a leading tab on the first record, bringing its output in line with that of rcollate. Not sure if this is any help. The reason I don't actually output columns on a single line with gendaymtx is that most text editors will choke on a 130 KByte line, although you can get that easily with something like "rcollate -oc 8760" if you want it. Passing to dctimestep (if that's your plan) is faster with the gendaymtx "-of" option, anyway, since you avoid the back-and-forth between ASCII and float representations that takes so much time.
