sddsdiff.c File Reference

Detailed Description

Compare two SDDS files for differences in definitions and data.

The program sddsdiff compares two SDDS (Self Describing Data Sets) files by analyzing their definitions (columns, parameters, arrays) and data, supporting various comparison criteria such as exact matches, numerical tolerances, and absolute differences. It provides detailed reports on discrepancies in definitions or data values.

Usage

sddsdiff <file1> <file2>
         [-compareCommon[=column|parameter|array]] 
         [-columns=<col1>[,<col2>...]]
         [-parameters=<par1>[,<par2>...]]
         [-arrays=<array1>[,<array2>...]] 
         [-tolerance=<value>] 
         [-precision=<integer>]
         [-format=float=<string>|double=<string>|longdouble=<string>|string=<string>] 
         [-exact] 
         [-absolute] 
         [-rowlabel=<column-name>[,nocomparison]] 
         [-ignoreUnits] 

Options

Option	Description
-compareCommon	Compare only common columns, parameters, or arrays.
-columns	Specify columns to compare.
-parameters	Specify parameters to compare.
-arrays	Specify arrays to compare.
-tolerance	Set numerical comparison tolerance.
-precision	Set the precision for numerical comparison.
-format	Specify the format for printing float, double, long double, or string data.
-exact	Compare values exactly (mutually exclusive with tolerance and precision).
-absolute	Compare absolute values.
-rowlabel	Use a column to label rows for comparison.
-ignoreUnits	Ignore units during the comparison.

Incompatibilities

• -exact is incompatible with:
  • -tolerance
  • -precision
