description: sddscollapse reads data pages from an SDDS file and writes a new SDDS
file containing a single data page. This data page contains only the values of the parameters
from the original file, with each parameter forming a column of the tabular data. In spite
of the simplicity of the command line, this is an extremely useful program. A typical use
might involve processing a multipage file using sddsprocess to, for example, obtain statistical
analyses of columns for each page; the results of such analyses are placed in parameters. Using
sddscollapse on this file would produce columns of statistical analyses, with one row for
each page. One might then further analyze the data using sddsprocess. One could also use
sddscombine to combine several collapsed, processed data sets into a single file, which puts
one formally back in the same position as when one started. In this fashion, multi-level data
analysis and collation is possible. This is done with some magnetic measurements at APS.
files: inputFile is the name of an SDDS data set to be collapsed. outputFile is the result. Note
that outputFile will not contain any information on the arrays or columns that are in
inputFile.
switches:
-pipe[=input][,output] — The standard SDDS Toolkit pipe option.
-noWarnings — Suppresses warnings about file overwrites.
