These scripts may be useful handling CarpetIOASCII data:
Carpet2ygraph.pl A perl script to convert to a format suitable for the xgraph or ygraph packages of P. Walker and D. Pollney.
mergeCarpetIOScalar.pl A perl script to remove duplicate datasets from file(s).
The first script resides in CarpetIOASCII/src/utils and was meant primarily to convert 1D data, since the CarpetIOScalar data format is easily readable also by ygraph. Anyway, this script converts also scalar data files to the original 2-column ygraph format. Usage: Carpet2ygraphCat.pl Inputfile.
The second script can be used to merge CarpetIOScalar output written before and after recovery. It reads one or
more files in CarpetIOScalar format and writes their contents to STDOUT, eliminating duplicate datasets (all
but the last occurance are discarded), which may be created when a run died abruptly without checkpointing at
the last output itaration and is recovered from a previous checkpoint. Usage: mergeCarpetIOScalar.pl list
of files.
Example 1: mergeCarpetIOScalar.pl alp.norm1.asc > alp.norm1.asc.merged.
Example 2: mergeCarpetIOScalar.pl alp.norm1.asc.firstCHKPT alp.norm1.asc.secondCHKPT >
alp.norm1.asc.merged.

This section lists all the variables which are assigned storage by thorn Carpet/CarpetIOScalar. Storage can either last for the duration of the run (Always means that if this thorn is activated storage will be assigned, Conditional means that if this thorn is activated storage will be assigned for the duration of the run if some condition is met), or can be turned on for the duration of a schedule function.
