Use —interval=undef to get all data.

Calculate the averages of 1-minute data from a lab data set. Use the “–mean” switch to da.export to have it output unweighted means from the statistics calculation when available. When it's not available (no averaging done) it will output the conventional values instead.

da.generate.edited --profile=aerosol_native `query.run 2` |da.select --include="Ba[BGR]_A1[145]" |da.avg --interval=undef |da.export --mean |transpose

Calculate segment averages for a lab experiment (example bash script). Note that this scirpt doesn't call da.avg, but it is included here because it generates averaged data.
