Detailed Description

Remove parts of a hierarchical data structure.

Parameters

selection - desired parts to be deleted (syntax explained in Selecting data)

Synopsis

Examples

# Delete dataset[i] groups 2...10 
rack volume.h5 --delete dataset2:10 -o volume-modified.h5
 
# Delete data[i] groups 3...20
rack volume.h5 --delete data3:20 -o volume-modified.h5
 
# Delete data[i] groups 3...20, in dataset[i] groups 2...10
rack volume.h5 --delete dataset2:10/data3:20 -o volume-modified.h5
 
# Delete independently dataset[i] and data[i] groups with two commands
rack volume.h5 --delete dataset2:6 --delete data2:5 -o volume-modified.h5
 
# Delete data[i] groups containing VRAD
rack volume.h5 --delete quantity=VRAD -o volume-modified.h5
 
# Delete data[i] groups containing VRAD in 1.0 degree sweeps and above
rack volume.h5 --delete elangle=1.0:90,quantity=VRAD -o volume-modified.h5
 
# Delete dual-PRF measurement data - leaving dataset groups
rack volume.h5 --delete prf=DOUBLE -o volume-modified.h5
 
# Delete dual-PRF measurement data - also dataset groups
rack volume.h5 --delete dataset:,prf=DOUBLE -o volume-modified.h5
 
# Delete actual data arrays
rack volume.h5 --delete data -o volume-modified.h5
 
# Delete quality[i] groups 
rack volume.h5 --delete quality: -o volume-modified.h5
 

Notice that –elangle applies to volume data only, and essentially selects dataset groups. Similarly, quantity selects data (and quality) groups. If selection parameters of both levels are issued in the same command, implicit AND function applies in selection.
