tpipe: Performs pipeline processing on a table
tpipe performs all kinds of general purpose manipulations
which take one table as input.
It is extremely flexible, and can do the following things
The basic operation of
tpipe is that it reads an
input table, performs zero or more processing steps on it,
and then does something with the output. There are therefore
three classes of things you need to tell it when it runs:
cmdparameters, or the name of a file containing the steps using the
scriptparameter. The steps that you can perform are described in Section 6.1.
omodeparameter. By default,
omode=out, in which case the table is written to a new table file in a format determined by
ofmt. However, you can do other things with the result such as calculate the per-column statistics (
omode=stats), view only the table and column metadata (
omode=meta), display it directly in TOPCAT (
The parameters mentioned above are listed in detail in the next section.
