What it does
This tool merges columns together. Any number of valid columns can be merged in any order.
Example
Input dataset (five columns: c1, c2, c3, c4, and c5):
1 10 1000 gene1 chr 2 100 1500 gene2 chr
merging columns "c5,c1" will return:
1 10 1000 gene1 chr chr1 2 100 1500 gene2 chr chr2
Note that all original columns are preserved and the result of merge is added as the rightmost column.
