Selection, Lines, Differences, Datasets
Subtracts an entire dataset from another dataset.
This tool subtracts an entire dataset from another dataset. The subtraction can be restricted to user defined columns for tab-delimited files.
You can restrict the subtraction to specified columns only if the input files are tab-delimited.
Blank and comment lines are skipped. They are not included in the output.
Duplicate lines are eliminated from both datasets. If any duplicate lines were eliminated, the number is displayed in the resulting history item.
If begin column is specified but end column is not: end column will be set to begin column automatically (and vice versa).
An empty dataset is output if both input files are identical or if you didn't selected the input files in the right order.
The begin column must be less than or equal to the end column. If it is not, begin column is switched with end column.
The output dataset contains the lines of the second input file which are not in the first input file.
Usage Example: identifying the differences between two datasets.
Restrict subtraction between 'begin column': c1
and 'end column': c4
