[Radiance-general] dctimestep error

[Germán Molina Larrain]

Yes.... smx files are huge. You could think on, instead of storing them,
just piping it to dctimestep, so you save storage.

gendaymtx -m 4 WEATHER.wea | dctimestep V T D > results

Maybe you can try deleting the -n option in dctimestep...?

You can allways use RMTXOP program as well.

Kind regards
